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.

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.

The taxonomic status of the taxa known to belong to Centaurea sect. Cynaroides and its close relatives was revised on the basis of herbarium specimens from the authors’ expeditions and other collections. It is established that Boissier is the correct author for C. sect. Cynaroides, and C. regia is designated as a lectotype of this section. Thirty seven species are recognised in the section. Three new species (C. kamalnejadii, C. mozaffarianii, and C. zarrei), four new subspecies (C. amadanensis subsp. ranjbarii, C. cataonica subsp. syriaca, C. gigantea subsp. rechingeri, and C. kurdica subsp. ciliata) and two varieties (C. regia var. longispinosa and C. regia var. purpurea) are described. Two subspecies are reduced to the variety rank, and two varieties are elevated to the subspecies rank. Centaurea sect. Paraphysis is reduced as a synonym of C. sect. Cynaroides. Centaurea onopordifolia is transferred from C. sect. Cynaroides to a new section, i.e. C. sect. Cardueae. Three lectotypes are designated, six lectotypes from previous lectotypifications are rejected and the author names for six species are corrected. The recognized taxa, the relevant synonyms, type details, examined specimen lists, full descriptions and a taxonomic key are provided for this section. Distribution maps are provided for each sections, species, subspecies and varieties. Images of the type specimens of all taxa and also photos of the species in its natural habitat and related fields are provided. Five chromosome counts (2n = 18) are reported for C. amadanensis subsp. amadanensis, C. amadanensis subsp. gymnoclada, C. nemecii, C. regia var. regia, and C. regia var. purpurea. Biogeographical distribution and ecology of taxa of C. sect. Cynaroides are presented and discussed. In addition, cytotaxonomy, homoploidy and evolution of C. sect. Cynaroides are illustrated and discussed. Finally, the pollination of C. sect. Cynaroides is illustrated, and also images of the pollinators of some species of the section are provided.

The taxonomy, rarity, and conservation status of Allium  L. is revised for the Canadian prairie provinces, based on analyses of herbarium specimens and fieldwork. Five species are recognized: Allium schoenoprasum  L., A. geyeri S. Watson var. tenerum M.E. Jones, A. textile A. Nelson & J.F. Macbride, A. cernuum Roth, and A. stellatum Ker Gawler. Distribution maps and a key to species are provided, as well as complete descriptions of the species examined, including new illustrations, information on nomenclatural types, synonymies, and chromosomal and ecological data. A lectotype is designated for A. geyeri var. tenerum. In this study, A. geyeri var. geyeri reported from Alberta and Saskatchewan and ranked in these provinces as having rarity levels S2 and S1, respectively, by the Nature Conservancy, is excluded from the Canadian flora and the rare list of these provinces because it was misidentified from a herbarium specimen of A. textile. Allium tricoccum Solander in W. Aiton is regarded as a non-native species to Manitoba. The rarity and conservation status of Allium in the Canadian prairie provinces is as follows: (i) A. schoenoprasum, listed as S2 in Saskatchewan, is rare in Manitoba, although its rarity status has not been formally assessed in the province; (ii) A. geyeri var. tenerum is the rarest Allium taxon, with distribution restricted to the Waterton Lakes National Park areas of Alberta, and is currently listed as S2; and (iii) A. cernuum was re-evaluated and a rarity level of S1S2 was recommended for the species in Saskatchewan, particularly in its southwestern distributional habitat.

Several taxonomic treatments of Styrax (Styracaceae) exist in regional floras of Asia, but the Asian species of the genus have not been comprehensively revised since 1907. A treatment of the Asian taxa of S. series Cyrta with imbricate floral aestivation was accomplished in 2003. To complete the taxonomic revision of S. series Cyrta, we conducted a taxonomic revision of the species of the series with valvate aestivation of the corolla lobes. Our revision comprises 11 species with a combined distribution from eastern India through southern China and Malesia, Melanesia, and Micronesia, although the group is absent from the Philippines. We resurrected S. bracteolatus, S. rubifolius, and S. warburgii as species to be recognized, and we corrected the misapplication of S. finlaysonianus, previously used for a species in S. series Benzoin. Styrax finlaysonianus and S. warburgii are segregated from the broader concept of S. agrestis recognized in prior treatments. The circumscriptions of the heretofore poorly delimited species S. confusus, S. faberi, and S. fortunei are clarified and their possible introgressants discussed. We observed unique combinations of characters in some problematic specimens whose taxonomic status remains unresolved because only single specimens with either flowers or fruits were available; at least some of these may represent undescribed species. Lectotypes are designated for Cyrta agrestis, S. argyi, S. bracteolatus, S. calvescens, S. casearifolius, S. confusus var. microphyllus, S. dasyanthus, S. dasyanthus var. cinerascens, S. faberi, S. finlaysonianus, S. formosanus, S. fortunei, S. fukienensis, S. henryi, S. henryi var. microcalyx, S. iopilinus, S. philadelphoides, S. rostratus, S. rubifolius, S. serrulatus var. agrestis, and S. virgatus. A neotype is designated for S. warburgii. Keys, descriptions, distribution maps, and conservation assessments are provided for all species. Styrax agrestis, S. bracteolatus, and S. rubifolius are rare endemics of conservation concern, with highly restricted distributions.

Abstract—Rogiera (Guettardeae, Rubiaceae) is a Neotropical genus distributed from Mexico to northern South America that includes shrubs, treelets, or trees, which were previously treated in the taxonomically controversial and confused Rondeletia complex. Rogiera can be recognized among other Rubiaceae by the combination of multiflowered inflorescences, heterostylous flowers, quincuncial corolla aestivation, a hairy ring at the corolla mouth, and capsular fruits with loculicidal dehiscence. Despite the recent taxonomic circumscription of Rogiera there is not a comprehensive taxonomic treatment to it. Moreover, regional floristic treatments disagree on the species circumscriptions, with discrepancies in the number of species of Rogiera from 11 to 20. Based on molecular and morphological evidence studied on field and herbarium specimens, we present a taxonomic revision of Rogiera. We recognize ten species; Mexico is the center of diversity with nine species, four of them endemic. An identification key, descriptions, distribution maps, nomenclatural history, phenological data, and illustrations of all the species in the genus are provided for the first time. Several names required lecto- or epitypifications designated here.

A taxonomic revision of Desplatsia Bocq. (Malvaceae s. lat. Juss., subfamily Grewioideae Hochr., tribe Grewieae Endl.) based on about 800 herbarium specimens is presented. Desplatsia is a genus of trees and shrubs found in tropical West and Central Africa and is characterized by subulately divided stipules, the absence of an androgynophore, stamens that are fused to a tube at the base, and large and distinctive fruits that are dispersed by elephants. Four species are recognized (D. subericarpa Bocq., D. chrysochlamys (Mildbr. & Burret) Mildbr. & Burret, D. dewevrei (De Wild. & T.Durand) Burret and D. mildbraedii Burret) and 12 species names are placed into synonymy, two of which have been put into synonymy for the first time: D. floribunda Burret syn. nov. and D. trillesiana (Pierre ex De Wild.) Pierre ex A.Chev. syn. nov. All four species are widely distributed and their conservation status is assessed as Least Concern (LC). A key to the species, full species descriptions, illustrations, a specimen citation list and distribution maps are provided.

The present revision focuses on the enigmatic Southwest Asian genus Aethionema in Iran based on taxonomic literature, fieldwork, and study of over 400 herbarium specimens. As a result of the present study, A. diastrophis and A. transhyrcanum are newly found for Iran. The former is morphologically closer to A. membranaceum and A. kopetdaghi rather than to A. spinosum, under which it was previously synonymized. Aethionema edentulum and A. levandowskyi are placed in the synonymy of A. membranaceum and A. grandiflorum, respectively. The genus is represented in Iran by 16 species, of which six are endemic. Detailed descriptions, distribution maps, IUCN conservation status assessments, and illustrations of the species are provided. The lectotypes of A. cordatum, A. elongatum, A. fimbriatum, A. grandiflorum, A. koenigii, A. moricandianum, A. pallidiflorum, A. pulchellum, A. recurvum, A. schelkownikowii, A. sintenisii, A. spinosum, A. stenopterum, A. umbellatum, A. virgatum, A. woronowii, Lepidium intricatum, and Moriera gracilis are designated.

A taxonomic revision and nomenclatural update for Paspalum sect. Pectinata is presented. This section comprises seven species distributed from southern Mexico to Peru, Bolivia and southern Brazil, and is characterized by having linear to lanceolate blades, inflorescences subdigitate or conjugate with a winged rachis, and upper glume and lower lemma 3–7-nerved. We include 16 names and propose lectotypes for Paspalum aspidiotes, P. contractum, P. cordatum, P. lanciflorum and P. pectinatum. Also, after examination of herbarium specimens, a new synonym for Paspalum reticulinerve is proposed. The revision was based on a review of the relevant literature, study of types and materials from 43 herbaria. Descriptions, distribution maps, illustrations and comments are presented for each species, and a key to all species is included.
