  • Microlicia coronata (Melastomataceae), a new ericoid species from the
           Serra das Almas, Bahia, Brazil

    • Free pre-print version: Loading...

      Abstract: Abstract: Microlicia coronata is described as a new species from Pico das Almas, Bahia, Brazil. It is morphologically similar to species of the Chaetostoma clade of Microlicia s.l., but can be recognized by its leaves lacking a keel (vs. keeled), bicolored, rostrate anthers (vs. yellow and apically attenuate), the ovary apex crowned with five bluntly triangular erect lobes 0.5–0.75 mm long on mature capsules (vs. ovary apex rounded), and the mature capsules not reaching the apex of the hypanthium (vs. exceeding the apex). Line drawings and a distribution map are provided for the new species, which is little-collected and apparently rare.

  • Taxonomic studies in the Miconieae (Melastomataceae): XV. Revision of
           Miconia sect. Menendezia

    • Free pre-print version: Loading...

      Abstract: Abstract A new section, Miconia sect. Menendezia, is recognized, characterized, and assessed phylogenetically. The section includes three species: M. angustifolia, M. biflora, and M. urbanii. All three have fruits with constricted hypanthia, and traditionally were included within an extremely non-monophyletic Tetrazygia. The monophyly of the section is supported by molecular analyses and morphology (i.e., calyx teeth flattened parallel to the associated lobe and equaling to much longer than the calyx lobes, and possibly also hypanthium constricted and calyx tube regularly tearing between the lobes). In addition, the inflorescence branches are flattened, although this condition is only poorly developed in M. angustifolia. Miconia urbanii (incl. M. stahlii) and M. biflora are morphologically distinctive (i.e., as evidenced by their strongly flattened inflorescence axes, flowers with an elongate hypanthium and calyx lobes, large petals that are undulate on one side, and fully inferior, slightly to strongly 4-lobed ovary) and these characters are likely synapomorphic for the putative M. urbanii + M. biflora clade, which was recognized as the genus Menendezia by N. L. Britton. Species descriptions, nomenclatural information, specimen citations, and eco-geographical characterization for each of the three species are presented, along with an identification key. Section Menendezia is well supported as a subclade within the Caribbean clade of Miconia, a morphologically heterogeneous clade of ca. 160 species (out of a total of some 1900 species in the genus). Finally, the names Calycogonium biflorum, Tetrazygia angustifolia, T. stahlii, and T. urbanii are lectotypified.

  • An updated synopsis of Aristolochia (Aristolochiaceae) in Guatemala

    • Free pre-print version: Loading...

      Abstract: Abstract The taxonomy, nomenclature and chorology of the species of Aristolochia (Aristolochiaceae) present in Guatemala are updated and discussed with respect to their current infrageneric classification. Specimens of Aristolochia deposited in 46 herbaria were examined for the present research, including specimens collected by the authors. A key to the infrageneric groups and species (17 of which are illustrated by photographs) is included. A total of 20 species are here reported for Guatemala, one of which (A. belizensis) is a new record for Guatemala. The presence of A. cordiflora in Guatemala is discussed. Aristolochia belizensis, A. salvadorensis, A. schippii and A. surinamensis recently placed under the synonymy of A. ovalifolia, A. arborea, A. leuconeura and A. trilobata, respectively, are reinstated as distinct species. Seven lectotypes (for A. aurantiaca, A. glaziovii, A. odoratissima, A. odoratissima var. grandiflora, A. ovalifolia, A. petenensis, and A. sericea) and one neotype (for A. arborea) are here designated. The species of Aristolochia from Guatemala belong to two of the three monophyletic subgenera, namely subgenus Siphisia (7 spp.) and subgenus Aristolochia (13 spp.). The latter belong to subsection Hexandrae (12 spp.) and subsection Pentandrae (1 sp.); the locality of the sole pentandrous species (A. pentandra) in Guatemala corresponds to the southernmost range extension of the entire subsection in Central America.

  • Remarks on aerophores and the relationship between sterome and stomata in
           ferns

    • Free pre-print version: Loading...

      Abstract: Abstract Nearly all ferns support their stems and leaf axes with a sheath of hypodermal sclerenchyma called sterome. The sheath consists of compact fibers with few or no intercellular spaces. Although solving the need for mechanical support, the sterome presents a problem: it blocks air that has diffused through the stomata from diffusing farther into the plant where it is needed for photosynthesis and respiration. In most ferns, the blockage is overcome by means of aerophores, which typically appear as light-colored lines flanking the leaf axes, with one line on either side. Each aerophore bears stomata and overlies a parenchymatous gap in the sterome. The gap contains intercellular spaces that facilitate the diffusion of air inward after it has passed through the stomata. Only rarely do stomata occur off the aerophore on areas of adjacent epidermis overlying the hypodermal sterome. In such locations, stomata would be useless because air diffusing through them would be blocked. In some ferns, aerophores also occur on rhizomes in association with decurrent leaf bases. Developmentally, aerophores arise from the marginal meristem. As such, they mark the boundary between the adaxial and abaxial surfaces of the leaf. Phylogenetically, aerophores constitute a synapomorphy for the clade consisting of the Cyatheales and Polypodiales. Within this clade, aerophores have become variously modified, including their complete loss, reduction to a single row of stomata, co-option as nectaries, and enlargement as peg-like structures at the pinna bases of mucilaginous leaves. Aerophores are absent in the Marattiaceae, which bear a different type of aerating structure here termed a porophore. These are scattered over the leaf axes, appearing as many pale, short longitudinal streaks, with each streak bearing a central pore.

  • Two new species of Microlicia (Melastomataceae) from Goiás state,
           Brazil

    • Free pre-print version: Loading...

      Abstract: Abstract Microlicia attenuata and M. versianeae, endemic to the state of Goiás, Brazil, are described, illustrated, and the preliminary conservation status for both species is provided. Microlicia attenuata differs from putative relatives in having few stalked glands in the branches, and sessile, golden glands sparsely distributed on the abaxial surface of the leaf blades, hypanthia, and sepals, while the adaxial surface is glabrous. In addition, it has lanceolate or obovate-lanceolate leaf blades that are semi-amplexicaul at the base, white petals, and yellow stamens, with polysporangiate anthers. Microlicia versianeae can be recognized by a pale-greenish hypanthium (when dry), white petals, dimorphic, concolorous, yellow stamens, and polysporangiate anthers. The branches, leaves, hypanthia, and sepals are covered only by sessile, golden glands. The leaves are imbricate, with the blade narrowly-lanceolate, discolorous, and revolute at the margin.

           de Janeiro State, Brazil

    • Free pre-print version: Loading...

      Abstract: Abstract During recent field expeditions to forest remnants in the state of Rio de Janeiro, Brazil, a distinctive Eugenia species was collected and is here proposed as a new taxon. This study is based on literature and herbarium and field collections. The conservation status was assessed based on the IUCN Red List categories and criteria. The map of occurrence records was built through QGIS Desktop software using shapefiles from open-source databases. The newly described Eugenia bragae is currently known only from the Atlantic Forest in the state of Rio de Janeiro, Brazil. It is here assigned to Eugenia subg. Pseudeugenia and compared with E. culicina. We also provide a table comparing the new taxon with E. altissima and E. laruotteana.

  • A critical review of type specimens for Polygala species (Polygalaceae)
           collected during the Malaspina Expedition of 1789–1794

    • Free pre-print version: Loading...

      Abstract: Abstract The names of sixteen species of Polygala (Polygalaceae) collected by Luis Née and Thaddeus Haenke during the Malaspina Expedition of 1789–1794 were published mostly by C. L. Willdenow in Species Plantarum (1802) and by C. Presl in Reliquiae Haenkeanae (1835). Resale and/or redistribution of a large part of the collected specimens to various herbaria had hindered proper application of these names. Based on a thorough study of the original material, manuscripts, and pertinent literature, a critical review of the type collections for Polygala acuminata Willd., P. coridifolia C.Presl, P. gnidioides Willd., P. linarifolia Willd., P. minutiflora C.Presl, P. mucronata Willd., P. myrtilloides Willd., P. neaei DC., P. pavonii Chodat, P. polifolia C.Presl, P. quadrangula C.Presl, P. ramosissima Cav., P. sulcata Willd., P. tenella Willd., P. thesioides Willd., and P. velutina C.Presl is here presented. Lectotypes are designed for P. acuminata Willd., P. coridifolia C.Presl, P. linarifolia Willd., P. minutiflora C.Presl, P. mucronata Willd., P. myrtilloides Willd., P. neaei DC., P. quadrangula C.Presl, P. ramosissima Cav., P. tenella Willd., P. thesioides Willd., and P. velutina C.Presl, and two names are synonymized, P. coridifolia C.Presl (= P. aspalatha L.) and P. quadrangula C.Presl (= P. mexicana Moc. ex Cav.). Also, an erroneous lectotype designation for P. gnidioides Willd. by Bernardi is corrected to a lectotype designated by Rankin Rodríguez and Greuter, an erroneous lectotype designation for P. pavonii Chodat is corrected to a first step neotype and a second step neotype designated, and an erroneous neotype designation for P. tenella Willd. is corrected to a lectotype.

  • The fern genus Saccoloma (Saccolomataceae) in Brazil, including new
           species and new combinations

    • Free pre-print version: Loading...

      Abstract: Abstract: Saccoloma is a medium-sized genus of ferns with taxonomic uncertainties and pending nomenclatural clarifications. Within the last 150 years, only four names have constantly been used for the Brazilian species. After a bibliographic review and analyses of ca. 270 collections, I present an updated taxonomic revision for those species. Here, nine species are recognized, of which four occur in Amazonia, four in the Atlantic Forest, and one in the Cerrado (= Brazilian savanna). They are: S. chartaceum, S. hieronymi, S. inaequale s.str., and S. membranaceum from Amazonia; S. catharinae, S. distans, S. elegans, and S. nigrescens from the Atlantic Forest; and S. matto-grossense, from the Cerrado. I present a key to species, descriptions, illustrations, maps of distribution, complete type information, nomenclatural clarifications, and full synonymy regarding Brazilian names. The name S. nigrescens (Mett.) A.Rojas, recently applied to plants from Costa Rica to Bolivia, is shown to be based on erroneous basionym and type information; Saccoloma nigrescens(Kunze) A.Rojas is the correct authorship, and it applies to a species endemic to the Atlantic Forest. Saccoloma hieronymi should be used for plants from Costa Rica to Bolivia. In total, 16 spp. are currently recognized for the Neotropics, and 24 worldwide (plus four varieties). I also present a preliminary, maximum likelihood, phylogenetic analysis using three chloroplast genes (atpB, rbcL, and rps4) to test the monophyly of Saccoloma and Orthiopteris. In the phylogeny, the 1-pinnateS. chartaceum (= Saccoloma s.str.) is nested among the 2–4-pinnate species of the genus, to which the name Orthiopteris has sometimes been applied. Orthiopteris could be applied, if desired, solely to the Old World species of the genus, which form a clade that is sister to the New World species. The following names are lectotypified: Davallia distans, D. inaequalis, D. nigrescens, Microlepia nigricans, S. elegans (second step lectotypification), and S. elegans var. costaricense.

  • A new species of Myriopus (Heliotropiaceae) from Brazil

    • Free pre-print version: Loading...

      Abstract: Abstract Myriopus eulinae (Heliotropiaceae), a new species from northeastern Brazil and associated with the Caatinga, Atlantic Forest, and Caatinga-Cerrado transition phytogeographic domain, is described and illustrated. The species can be morphologically recognized by its discolored leaf blade, lax inflorescences, and strigose to hirsute fruits. We discuss its habitat, flowering and fruiting, taxonomic affinities, distribution, and conservation status.

  • Taxonomic notes on Iochrominae (Solanaceae: Physalideae) from Brazil

    • Free pre-print version: Loading...

      Abstract: Abstract The subtribe Iochrominae (Solanaceae) is represented in Brazil by two species, both with broad morphological variation. No study focusing on this subtribe has been published for the country to date. Therefore, the aim of this study is to provide a taxonomic treatment for the Iochrominae occurring in Brazil. Iochroma arborescens is widely distributed across eastern Brazil, with a few collections reported from the Central-West region of the country; whereas Vassobia breviflora occurs in the subtropical zone of the country, mainly in the South region, but also with a few records from the Southeast region. Complete descriptions, illustrations, and distribution maps for the two species are presented here. Five lectotypes are also designated.

  • Taxonomic novelties of Ronnbergia (Bromeliaceae: Bromelioideae) from
           Colombia

    • Free pre-print version: Loading...

      Abstract: Abstract Three new species of Ronnbergia (Bromeliaceae: Bromelioideae) and two new records of the same genus for Colombia are described. The three new species correspond to (1) Ronnbergia igneosepala from the slopes of the Western Cordillera in Nariño (Colombia), which is unique by its orange floral bracts and sepals; (2) R. robusta from the Pacific Littoral of Colombia, which can be easily recognized by its involucrate peduncle bracts that only cover 1/3 of the inflorescence, green to dull-purple sepals and long sepal mucros; and (3) R. veitchioides, a species from the isolated mountain peak of Cerro del Torrá (Chocó) that can be identified by its serrulate, purple, reflexed floral bracts, and long sepals. We report the occurrence of R. campanulata in the department of Cauca, almost 800 km apart from the already known populations in the Cordillera del Condor of southern Ecuador. Moreover, we register R. aciculosa in Colombia and provide a short discussion on the differentiation of this species from R. tonduzii.

  • Leucoagaricus taniae sp. nov. (Agaricaceae), a sand-dwelling mushroom from
           Brazil

    • Free pre-print version: Loading...

      Abstract: Abstract: Leucoagaricus taniae (Agaricaceae) is described as new to science. It was found growing in sand at Armação beach on Santa Catarina Island in Southern Brazil covered by sand among Canavalia rosea (Fabaceae) and Cyperus pedunculatus (Cyperaceae). The new species has a cream white pileus that is up to 50 mm in diameter and exudes golden drops when fresh. The stipe is up to 60 mm height, with rhizomorphs at the end of the volvate base. Photographs of fresh basidiomes in situ and illustrations of the main micromorphological features are presented. A molecular-phylogenetic analysis that includes the species is also presented.
