A new genus of Orchidaceae (Polystachyinae), <em>Isochilostachya</em>, is described. It is morphologically similar to <em>Polystachya </em>Hook. but is distinct by the narrower, grass-like leaves arranged in the upper part of the stem, long and acuminate floral bracts and sepals, and long clavate or capitate hairs densely arranged on the lip. A comprehensive description of the new genus is provided. A list of examined specimens and information about distribution, habitat, and altitude for each species are presented. A position of the members of the new genus in the cladogram recently obtained from molecular analyses of Polystachyinae is briefly discussed. A taxonomic key to Polystachyinae is included. Eleven new combinations on species level are validated. Eight lectotypes are designated. Most of the species of <em>Isochilostachya</em> are endemic to particular mountains of the Eastern Arc (Eastern Afromontane hotspot) in north-east Tanzania therefore a brief discussion about their restricted distribution is provided.

A taxonomic revision of Flemingia subg. Rhynchosioides based on morphology and molecular information (matK and ITS) is presented. The subgenus comprises six herbaceous taxa (F. gracilis, F. mukerjeeana, F. nilgheriensis, F. rollae, F. tuberosa and F. vestita). All species except F. vestita are endemic to India. Morphological evidence and molecular phylogeny revealed that the subgenus is monophyletic. Nevertheless, the systematic position of F. tuberosa remains unclear on account of its unique ecology and inflorescence. A new species, F. mukerjeeana, is described and four binomials, namely F. gracilis, F. nilgheriensis, F. tuberosa and F. vestita have been lectotypified. Furthermore, all species have been described, illustrated and their ecology discussed. A taxonomic key including the recently described species from Thailand, F. sirindhorniae, is also provided for easy identification.

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.

Previous morphological and molecular studies indicate that the genus Leiothrix is a monophyletic and well supported clade in Eriocaulaceae. A taxonomic revision of the genus for the Flora Neotropica is in progress, but with the Flora do Brasil 2020 project now in its final stages, this synopsis became necessary to present an updated list of accepted species, their synonyms and typifications. Protologues and types of 122 previously published names have been reviewed. The genus now includes 39 species and six varieties, adding up to 42 taxa endemic to Brazil, occurring especially in the Espinhaço Range in Minas Gerais and Bahia States. One species extends from Brazil to other countries of northern South America and one species and one variety are found only in Venezuela. In this paper I propose 34 new synonyms, five new combinations, three changes of status, one neotype and 49 lectotypes.

Based on field work and herbarium studies, a taxonomic revision of the genus Orbilia in the Canary Islands was carried out. Eighteen species of the genus are recognized in the present study. Eight of these are new records for the archipelago (Orbilia cejpii, O. euonymi, O. flavida, O. flavidorosella, O. hesperidea, O. scolecospora, O. vinosa and O. vitalbae). Three of them are here described in detail (O. cejpii, O. flavida and O. vitalbae), because they were not reported again since their first publication. Corrections and clarifications about the identity of four previously reported species (O. alnea, O. auricolor, O. delicatula and O. epipora) are provided, being renamed to O. eucalypti, O. tenuissima, O. xanthostigma, and O. dryadum, respectively, the last one being a new combination for O. alnea var. dryadum. Two species with a rather short original diagnoses reported for the Canary Islands are redescribed in detail (O. corculispora and O. gambelii), and those being endemic for the archipelago are illustrated and briefly discussed (Orbilia adenocarpi, O. asomatica, O. pisciformis and O. succulenticola). A key for the identification of these species, a discussion about closely related taxa, notes on their global distribution, and ecological data are provided.

The formicine ant genus Prenolepis is here revised for the first time. Thirteen extant species are recognized of which four are described as new. A key for the worker caste is provided, and the worker of each species is imaged, with males and queens imaged in species where they are known. Worker-based characters were used to construct a species-level phylogeny of Prenolepis. Both maximum parsimony and Bayesian inference methods were used for the phylogenetic analyses. A morphological diagnosis for the genus is provided, with a discussion of useful morphological characters for separating Prenolepis from other genera in the Prenolepis genus-group. Major taxonomic changes are proposed. The new species are: P. darlena, P. fustinoda, P. mediops, and P. shanialena. Prenolepis jerdoni subopaca is elevated to full species. Three species are excluded from Prenolepis and transferred to Nylanderia and Paratrechina as new combinations: N. emmae, N. flaviabdominis, and P. umbra. Two species are excluded from Paratrechina and transferred to Nylanderia and Paraparatrechina as new combinations: N. guanyin and P. kongming. One species, Z. darlingtoni, is excluded from Nylanderia and transferred to Zatania as a new combination. Several synonyms are proposed: Prenolepis sphingthoraxa = Nylanderia flaviabdominis; P. imparis arizonica, P. imparis colimana, P. imparis coloradensis, and P. imparis veracruzensis = P. imparis; P. melanogaster carinifrons and P. nigriflagella = P. melanogaster; P. longiventris and P. magnocula = P. naoroji; and P. septemdenta = Nylanderia opisopthalmia.

The lichen family Teloschistaceae from the Galapagos is revised. Most of the species belong to the Caloplacoideae, two to Teloschistoideae and a few to Xanthorioideae, three subfamilies not validly published, which is remedied here. Four different datasets were analyzed using Bayesian inference. For the bulk of the species, a combined dataset of nrITS, nrLSU and mrSSU was analyzed. Additionally, three analyses were performed using nrITS to further investigate phylogenetic relationships within and between species in each subfamily, and in the genera Xanthomendoza and Squamulea. Four new genera are described: Lacrima, Oceanoplaca, Phaeoplaca, Sucioplaca. Twenty-four species are reported, of which ten are new to science: Caloplaca nigra, Lacrima galapagoensis, Oceanoplaca chemoisidiosa, O. sideritoides, Phaeoplaca tortuca, Squamulea chelonia, S. humboldtiana, S. osseophila, S. oceanica, and Xanthomendoza leoncita. Several new combinations are proposed and three species of Xanthomendoza are reduced to synonymy. Several new combinations and species placed into synonymy do not occur in the Galapagos, but are treated as a consequence of our taxonomic revision. Morphology, anatomy, secondary chemistry, distribution and molecular phylogenetic affiliation are presented for each species and a key is provided. Eight different chemical patterns are quantitatively described based on HPLC analyses. The new genus Lacrima includes L. galapagoensis, a species without vegetative propagules, and two densely isidiate species, L. epiphora and L. aphanotripta that are morphologically similar to ‘Caloplaca’ wrightii. The only species of Galapagos Teloschistaceae that contains xanthones is placed into Huneckia. Oceanoplaca includes two species with the new anthraquinone isidiosin, O. isidiosa and O. chemoisidiosa, while a third species, O. sideritoides, does not contain this secondary metabolite. Phaeoplaca camptidia has previously been reported from Galapagos, but our phylogenetic analysis suggests that it is a new species, here named P. tortuca. An isolated position is occupied by ‘Caloplaca’ diplacia, which we place in it its own monotypic genus Sucioplaca. Some Galapagos Teloschistaceae can be considered a ‘residue’ of unresolved Caloplaca s.l., i.e. the corticolous C. floridana is possibly related to the saxicolous C. nigra, while C. cupulifera can currently not be placed. Squamulea remains particularly problematic and includes S. phyllidizans, that is nested among otherwise unresolved Squamulea species. Based on molecular data, S. phyllidizans is close to ‘Huriella’. ‘Huriella’ flakusii, described from Peru, is confirmed to occur in the Galapagos and the genus is reduced to synonymy with Squamulea. The Squamulea squamosa/subsoluta group remains largely unresolved, but the new species S. chelonia, S. humboldtiana, S. oceanica, and S. osseophila are phylogenetically distinct. Foliose Teloschistaceae are represented only by one species, described as Xanthomendoza leoncita, while the only fruticose species, Teloschistes chrysophthalmus and T. flavicans, are cosmopolitan.
