A New Species

Comolia abaetensis, an endemic new species from the Abaeté and Itapuã sand dunes, Bahia, Brazil, is described and illustrated. Additionally, field images and a geographic distribution map of the new species are provided, together with morphological and leaf anatomy comparisons among the most similar congeners, and a dichotomous key to the species that occur in Brazil. Comolia abaetensis is morphologically similar to C. ovalifolia, but differs from the latter by the following combination of characteristics: glabrous (rarely with sparse trichomes)internodes and hirsute nodes, glabrous leaf blades or rarely with sparse eglandular trichomes, abaxial surface predominantly red with green nuances, glabrous pedicels, cupuliform hypanthium, and filaments of the antesepalous stamens that are 5–6 mm long. Specimens of C. abaetensis have been confused with and/or tentatively determined as C. berberifolia. However, these two species are readily distinguished by the size of the leaves, the length of the trichomes and filaments, and the color of the abaxial foliar surfaces. Comparisons between the leaf anatomy ofC. abaetensis and C. ovalifolia are provided and the occurrence of emergences and hydathodes are here reported for the genus for the first time. Finally, we informally recommend a conservation status of Critically Endangered [CR B1ab (iv) + 2ab (iv)] for C. abaetensis.

A New Species

A synopsis of the genus Cnidoscolus is presented for the midwestern region of Brazil, which resulted from the analysis of about 1,200 specimens from 62 national and foreign herbaria, including type collections. Observations of populations in field were also made. Nine species are recognized, one of which, C. mcvaughii, is new to science. It is described and illustrated, and comments about its geographic distribution, morphological relationships, systematic position, phenology, and conservation status are provided, as well as images and a map. The other species are contrasted by a dichotomous key. Also, distributional information, maps, conservation evaluations, images and morphologically diagnoses are included. Eight synonymizations, one lectotypification, a neotypifcation, and the re-establishment of C. neglectus are proposed.

A New Species

The species of Centris of the hyptidis group are revised. The group, composed by C. hyptidis Ducke, C. hyptidoides Roig-Alsina, and C. thelyopsis n. sp., exhibits unique morphological characters within the genus, like foreand midtrochanters with a laminar expansion at the base, and elaiospathes strongly modified. An updated catalog, and floral and distributional records are provided for each species, as well as an identification key and a distribution map. The male of C. hyptidoides is described for the first time and a modern diagnosis for C. hyptidis is presented. A new species, C. thelyopsis n. sp., is described from Goiás State, in central Brazil. It can be easily distinguished from the two previously known species by its predominant orange pilosity, including that of the hind legs and metasoma.

A revisional taxonomic study of Adesmia subg. Adesmia ser. Bicolores has unveiled a new species from southern Brazil. Adesmia miottoae is described and illustrated here. Its geographic distribution, phenology, conservation status and morphological similarities with its closest relatives, Adesmia punctata and A. incana, are presented. The species is distinguished by glandular trichomes covering all the aerial parts of the plant, except the corolla. These trichomes are shorter than those of Adesmia punctata. Additionally, a detailed anatomical description of the leaflet blade is provided.

A New Species

Abstract—Merostachys delicatula, a new species recorded thus far only from the montane Atlantic forest of southern Bahia, is described and illustrated here. Comments on its taxonomy, distribution, habitat, and phenology are presented. Among the narrow-leaved congeners occurring in Bahia, the new species is most similar to M. leptophylla. It is distinguished by having internodes glabrous to scabrous (vs. glabrous in M. leptophylla); internodes with an infranodal band of trichomes (vs. absent); culm leaf sheaths abaxially scabrous (vs. glabrous); upper glumes 1.2‐2.1 mm wide (vs. 3.5‐4 mm); anthecia dull (vs. shiny); lemmas 1.5‐2.7 mm wide, abaxially pubescent (vs. ca. 4 mm, glabrous); and paleas 1.2‐2.3 mm wide (vs. ca. 4 mm). We also provide an assessment of the conservation status of the new species and a geographic distribution map for both species.

A New Species

A new species of Lippia endemic to the Brazilian Atlantic Forest is described and illustrated. Lippia diversifolia is currently known from the inselbergs of Espírito Santo and Rio de Janeiro and is characterized by markedly tetragonal branches, of which the opposed sides are densely strigose and the other glabrescent, with indument alternating in the subsequent internode, leaf blade cartaceous to coriaceous, adaxial surface strigose, abaxial surface tomentose or strigose, peduncle 3.5–9 cm long, bracts strigose with apex acute, inconspicuous calyx, and white sessile glands along the whole plant. We provide field photographs, distribution map, conservation status and a table with the main characters that distinguish it from Lippia rubella, which is a morphologically similar species.

Solanum mellobarretoi, a new species of Solanum subg. Leptostemonum (Solanaceae), is described and illustrated. It is endemic to Brazil and restricted to the southern Espinhaço Range in the State of Minas Gerais, southeastern Brazil. Solanum mellobarretoi is morphologically related to S. leptostachys Dunal, from which it differs by its irregularly lobed lanceolate to ovate-lanceolate leaves, irregularly lobed, ovate to lanceolate calyx lobes, larger flowers, and pentagonal rotate corolla with cuspidate lobes. Although known in other groups of Solanum, the explosive seed dispersal mechanism found in this species is described here for the first time for the spiny solanums. The affinities with S. leptostachys, geographic distribution, ecology and conservation status of S. mellobarretoi are discussed.

The new species Oiovelia shepardi is described based on macropterous specimens from the departments of La Guajira and Antioquia in northwestern Colombia, and is compared to its presumed closest relative. The female of Paravelia cunhai Rodrigues & Moreira, 2016 and the male of P. polhemusi Rodrigues, Moreira, Nieser, Chen & Melo, 2014 are described for the first time. The specimens of the two species of Paravelia Breddin were collected in waters inside caves in the State of Pará, northern Brazil. Further, the micropterous form of Steinovelia vinnula (Drake, 1951) is described, compared with S. virgata (White, 1879), and new distributional records are provided. Illustrations and a geographic distribution map of all species treated here are presented.

A New Species

Polystachya orophila, a new species of Orchidaceae, is described based on specimens collected during the baseline study of the Guinean Nimba Mountains for the environmental impact assessment for a proposed mining project. While material belonging to this species was mentioned as early as 1920 by Chevalier, it has historically been confused with P. microbambusa, from which it differs by its typically Polystachya-like clustered pseudobulbs, placing it in P. sect. Polystachya, whereas P. microbambusa has pseudobulbs successively growing on top of one another, forming developed and persistent stems, and is the sole representative of P. sect. Dimorphocaules. The complex taxonomic and nomenclatural history of P. microbambusa is also clarified. For both taxa we provide a morphological description as well as information on distribution, habitat, and phenology, an IUCN conservation status assessment using the Red List criteria, and a distribution map, along with a dichotomous key that also includes the most similar members of P. sect. Polystachya.

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.
