A taxonomic revision is presented for the genus Chorizema Labill. The circumscription is enlarged slightly to include three species formerly in Oxylobium Andrews. Of the 26 taxa recognised, three species and one subspecies are described as new: C. circinale, C. retrorsum, C. ulotropis, and C. aciculare subsp. loxum respectively. Three new intergeneric combinations are made: C. carinatum, C. obtusifolium, C. spathulatum; one new infrageneric combination is made: C. racemosum; and three names are reinstated: C. humile, C. nanum, and C. rhynchotropis. A key, descriptions, illustrations and distribution maps and notes are provided for all taxa. Lectotypes are chosen where necessary. Relationships between species are analysed cladistically and, on this basis, a new infrageneric classification including three sections, of which two are new (Parviflores and Hirtistylis), is constructed.

In the present study, we presented a taxonomic revision of the genus Sorbaria (Sorbarieae; Amygdaloideae) with a new infrageneric classification. Moreover, we extensively reviewed various data for Sorbaria species, including previous anatomical, micromorphological, and palynological data. The new sectional classification was based on morphological, micromorphological, and palynological evidence, with two sections: sect. Sorbaria aut. and sect. Kirilowiana J.-H. Song & S.-P. Hong (sect. nov.). Overall, four species and five varieties (including two nomenclatural novelties) were recognized: S. sorbifolia (Linnaeus) A. Braun var. sorbifolia, S. sorbifolia var. glandulifolia J.-H. Song & S.-P. Hong, S. sorbifolia var. stellipila Maximowicz, S. pallasii (G. Don) Pojarkova, S. tomentosa (Lindley) Rehder var. tomentosa, S. tomentosa var. angustifolia (Wenzig) Rahn., S. kirilowii (Regel & Tiling) Maximowicz var. kirilowii, S. kirilowii var. arborea (C.K. Schneider) J.-H. Song & S.-P. Hong (comb. & stat. nov.), and S. kirilowii var. dubia (C.K. Schneider) J.-H. Song & S.-P. Hong (comb. nov.). Some illustrations and syntype were designated as the lectotype for several names. The classification was based on a comprehensive morphological examination of herbarium specimens, including field observations and observations of types, micromorphological, and palynological characteristics. In addition, we provided an identification key, diagnostic characteristics, full descriptions, comprehensive nomenclatural treatments and taxonomic notes (including complete synonymy), and distribution maps of Sorbaria species.

Biological Aspects

A taxonomic revision of Calytrix Labill., an Australian endemic genus of Myrtaceae, tribe Chamelaucieae, is presented. Lhotskya Schauer is reduced to a synonym of Calytrix. Seventy-two species are recognized of which the following 22 are described as new: C. amethystina, C. carinata, C. chrysantha, C. divergens, C. duplistipulata, C. eneabbensis, C. erosipetala, C. formosa, C. gurulmundensis, C. gypsophila, C. habrantha, C. islensis, C. microcoma, C. parvivallis, C. paucicostata, C. platycheiridia, C. praecipua, C. rupestris, C. similis, C. truncatifolia, C. verruculosa and C. warburtonensis. Two species comprise two subspecies each, of which one, C. simplex subsp. suboppositifolia, is also described as new. Other than autonyms the following new names result from the transfer of Calycothrix and Lhotskya species to Calytrix, and/ or changes in taxonomic rank: C, acuttfolia, C, breviseta subsp. stipulosa, C. brownii, C. drummondii, C. glaberrima, C. harvestiana, C. merrelliana, C. nematoclada, C. purpurea, C. smeatoniana and C. sylvana. Distinctive features of the morphology are discussed. A new term, cheiridium, is proposed for an apparently adaptive structure formed from the peduncle and persistent, connate bracteoles. Other biological aspects that are discussed briefly include floral biology, fruit and dispersal, and geography. An informal infrageneric classification, based largely upon floral features, is outlined. New taxa are illustrated. Distribution maps are provided for all taxa.

Homalolepis Turcz. is a neotropical, monophyletic genus, recently reestablished as a segregate from Simaba Aubl., based on molecular and morphological grounds. As here defined, Homalolepis comprises 28 species, mainly distributed in tropical South America, with one species extending to Central America. Most species occur within the Cerrado and Atlantic forest domains in Brazil and only a few species occur in the Caatinga and Amazonian domains or in other countries. Most of the species are narrow endemics, and two (H. suaveolens and H. maiana) are presumably extinct. The present revision treatment is primarily based on the examination of about 1300 specimens from 58 herbaria. Natural populations of 20 species were also studied. Extensive field work improved the representativeness of collections of several species which were poorly known until now, and it was critical for achieving accurate species circumscriptions, especially for some species complexes present in the genus. Twenty-three species were transferred from Simaba to Homalolepis, seven names lectotypified, an epitype designated, seven new species described, and one reestablished. The infrageneric classification is reevaluated, with an updated morphological circumscription of two traditional sections. This revision provides the taxonomic data on nomenclatural types, including synonymies, morphological descriptions, etymology of species names, common names and uses, illustrations and photos, and brief discussions on phenology, taxonomy and nomenclature. Distribution maps are provided for each species, along with biogeographical and ecological comments.

Respective Species

The South American genus Panca Evans, 1955 and its respective species are revised. Previous to this study, the genus included solely its type species, Lerodea subpunctuli Hayward, 1934, until Panca moseri Dolibaina, Carneiro & O. Mielke, 2017 was described recently. However, as a result of a broader morphological study including closely related genera, we here propose that Panca assembles 12 species, most of which inhabit open environments such as the Cerrado biome and the natural grasslands of the Atlantic Forest biome. Eight species formerly included among other genera of Moncina are here combined with Panca: Panca satyr (Evans, 1955) comb. nov., Panca tobiasi (Mielke, 1992) comb. nov., Panca trogon (Evans, 1955) comb. nov., Panca steinhauseri (Dolibaina & A. Warren, 2015) comb. nov., Panca acroleuca (Plötz, 1884) comb. nov., and Panca mirnae (O. Mielke, Dolibaina, Carneiro & A. Warren, 2015) comb. nov. (all formerly in Artines Godman, 1901), Panca paulo (Bell, 1932) comb. nov. (formerly in Eutocus Godman, 1901), and Panca mictra (Evans, 1955) comb. nov. (formerly in Vidius Evans, 1955). Additionally, two new species are described from Brazil: Panca puri Medeiros, O. Mielke & Casagrande sp. nov. (from Pará, Pernambuco, Minas Gerais, Rio de Janeiro and Paraná) and Panca xavante Medeiros, O. Mielke & Dolibaina sp. nov. (from Mato Grosso, Goiás, Distrito Federal and Minas Gerais). A neotype for Apaustus acroleuca Plötz, 1884 is designated. Illustrations of the male and female genitalia and distribution maps are presented for all the species of Panca and an identification key is provided for both sexes.

AbstractThe conservation status of threatened taxa may be obfuscated by the detection of cryptic species complexes, in both vertebrate and invertebrate species. African dwarf crocodiles (Osteolaemusspp.) are hunted throughout their range but their conservation status is unknown. Few population assessments have been carried out and there has been a taxonomic revision of the number of species in the genus. The similar morphologies ofOsteolaemus tetraspisandOsteolaemus osbornipose a challenge for conservation in Cameroon, where they are still managed as a single species. Nocturnal spotlight surveys were conducted in three regions during August–November 2010 and December 2011–February 2012 to provide population assessments ofO. tetraspisandO. osborniand raise awareness of the two species in Cameroon. The mean encounter rates ofO. tetraspisandO. osborniwere 1.02 ± SD 1.34 (65 individuals in 39 surveys) and 0.61 ± SD 0.38 (three in four surveys) crocodiles per km, respectively. TheO. tetraspispopulation comprised juveniles predominantly and had a male-biased sex ratio. The fewO. osbornidetected comprised both adults and juveniles. Both species are threatened in Cameroon, based on low encounter rates, young population structures and the threats of habitat loss and hunting pressure. This study provides distribution maps and serves as a baseline to quantify population trends and inform conservation strategies.

ABSTRACT The taxonomic revision of Amorimia (Malpighiaceae) is presented, including typifications, and descriptions for all accepted species. The genus is endemic to Seasonally Dry Tropical Forests and Rainforests of South America, and its species can be distinguished by morphological details of leaves, indumenta, inflorescences, flowers, and fruits. This study includes an identification key for the subgenera and species of Amorimia, illustrations, distribution maps, conservation risk assessments, and comments on ecology, nomenclature, and taxonomy for all species. Additionally, I provide a key to differentiate Amorimia from the remaining genera of the Malpighioid clade.

A taxonomic revision of the Brazilian species of Encyclia is presented, based on analysis of roughly 1,400 herbarium specimens, including types. Thirty-nine species and one variety are listed for Brazil; we indicate 101 synonyms, of which eight are newly proposed. Lectotypes are chosen for five names (E. chironii, E. dutrae, E. paraënsis, E. tripartita and Epidendrum capartianum), including accepted names and synonyms. Two names are indicated as invalid (E. randii var. rondoniensis and E. vazzoleri), one name as a nomen nudum (E. guesneliana) and another as superfluous (Epidendrum pabstii). The occurrence of E. auyantepuiensis and E. thienii is confirmed for Brazil, and new occurrences are documented of E. fimbriata in Minas Gerais (in addition to Bahia) and E. linearifolioides in Maranhão and possibly Paraná (in addition to Matto Grosso and Tocatins States and Bolivia and Paraguay). All species are described and illustrated, and distribution maps are included. For both varieties of E. patens, nomenclatural and taxonomic notes are provided.

Family Tecophilaeaceae subfam. Tecophilaeoideae is revised for the Flora of southern Africa region, with the inclusion of the tropical Walleria mackenzii J.Kirk for completeness. The genera Cyanella Royen ex L. (9 spp.), Eremiolirion J.C.Manning F.Forest (1 sp.) and Walleria J.Kirk (3 spp.) are treated, with keys to the genera, species and subspecies; and full descriptions and distribution maps. A formal infrageneric classification is proposed for Cyanella, in which sect. Trigella (Salisb.) Pax K.Hoffm. is revived for the species with a 3 + 3 arrangement of stamens. The new species, C. marlothii J.C.Manning Goldblatt, is described from the Richtersveld; and C. pentheri Zahlbr. is resuscitated from the synonomy of C. hyacinthioides Royen ex L. Pink-flowered plants of normally yellow-flowered C. lutea have a separate geographical distribution and are recognized as subsp. rosea (Eckl. ex Baker) J.C.Manning Goldblatt.
