A taxonomic revision of the genus Podagrostis (Griseb.) Scribn. & Merr. is presented, including two new combinations: P. meridensis (Luces) A. M. Molina & Rúgolo and P. novogaliciana (McVaugh) A. M. Molina & Rúgolo. Podagrostis bacillata (Hack.) Sylvester & Soreng constitutes a new report for Colombia. Information regarding synonymy, geographical distribution, habitat, iconography, and vernacular names is provided along with complete illustrations and a list of additional specimens examined. A key for the identification of the species is included as well as a comparative table based on macro- and micromorphological data. The anatomical character of Trichodium net on lemma epidermis, as well as its diagnostic value, is discussed in species of Podagrostis and most related genera (e.g., Agrostis L., Chaetotropis Kunth, and Polypogon Desf., among others).

The genus Morinda L. (Rubiaceae) has been revised for its species diversity in the flora of Bangladesh. The genus is represented by five species, viz., M. angustifolia Roxb., M. citrifolia L., M. persicaefolia Ham., M. pubescens Smith and M. umbellata L. Of these, M. pubescens Smith is a new record for Bangladesh. A key to the species with vernacular names, descriptions, illustrations, photographs, ecology, uses, geographical distribution and status of occurrence in the flora is provided.

This taxonomic revision of the continental African species of Monanthotaxis (Annonaceae) includes 79 species and one variety. Thirteen new species (M. aestuaria, M. bidaultii, M. confusa, M. glabra, M. hexamera, M. mcphersonii, M. quasilanceolata, M. sterilis, M. submontana, M. suffruticosa, M. ursus, M. vulcanica and M. wieringae) are described and 5 new combinations (M. biglandulosa, M. kenyensis, M. ochroleuca, M. pynaertii and M. seretii) are made. The genus Monanthotaxis consists of lianas or lianescent shrubs. It occurs throughout forests in tropical Africa and the highest species diversity is found in the Western Central African rain forests. A key for flowering material is provided, just like a synoptic key including 45 characters. Topics included in the revision are the history of the taxonomy of Monanthotaxis, morphology, leaf anatomy, floral biology, distribution and habitat, phylogeny and finally ethnobotany and phytochemistry. Each species is fully described including synonymy, notes on distribution, habitat & ecology, vernacular names, uses and a preliminary IUCN conservation status. Distribution maps are provided for all species, illustrations for 48 species and photographs of 22 species. An index of exsiccatae and an index of the scientific names are included at the end.

A taxonomic monograph of a re-circumscribed Leandra sect. Leandra is presented. The new circumscription is based on a previous phylogenetic hypothesis, and diagnostic morphological characters are discussed. Four new combinations to Leandra are proposed, one from Clidemia (L. capilliflora) and three from Ossaea (L. capitata, L. cogniauxii and L. loligomorpha). Additionally, eight species are treated as synonyms for the first time, and 15 lectotypes are designated. A review of the 17 recognized species, including descriptions, synonymy, illustrations and distribution maps, is provided. This work also includes an overview of general morphology, leaf and flower anatomy, phenology and geographical distribution. Species with a history of taxonomic problems and/or with distinctive morphotypes are further investigated with morphometrics tools.

Dissochaeta is a plant genus of woody climbers, classified in the tribe Dissochaeteae (Melastomataceae). The taxonomic history of the genus is complicated and includes some allied genera like Dalenia, Diplectria, Macrolenes and Omphalopus. Most of them are already regarded as synonyms of Dissochaeta except for Macrolenes which is considered a separate genus here as well. Dissochaeta is characterised by its scrambling habit, interpetiolar outgrowths, 4-merous flowers, dimorphic stamens and berry-like fruits. A taxonomic revision of Dissochaeta is presented, which includes references, a complete list of synonyms, detailed morphological descriptions of the species and an identification key, as well as information on the distribution, habitat and ecology, vernacular names, notes and lists of examined specimens. Fifty four species and two varieties of Dissochaeta are recognised. We designate several lectotypes, propose eleven new combinations and we describe one new species and one new variety.

This taxonomic revision of Ontario Crataegus (Rosaceae) indicates the presence of 39 good species in 14 series in the province. This appears to represent about one-third of the taxa of North American Crataegus. Additionally, six "little-known" species are briefly described. The reasons for taxonomic difficulty in Crataegus in eastern North America are fully discussed and attention is drawn to the care with which specimens must be collected and the characteristics known to be of diagnostic value. A key to and descriptions of the series are provided. A key to species is followed by descriptions of each. Line drawings of 25 species at anthesis are provided to indicate the range of variation in Ontario Crataegus and to underline discriminating features. This is the only pictorial record of this detail for Ontario Crataegus. Thirty-two colour figures emphasize the differences among fruiting Crataegus, which have hitherto caused much confusion to collectors. Thirty-five species are mapped for their Ontario distribution and exemplar specimens are cited for all taxa. Seven new combinations have been made. Our species concepts are not consistent because of the range of variation patterns found in the genus, from ordinary sexual outbreeders through polytypic forms with various cytotypes to situations where hybrid swarms may be suspected. The taxonomic situation is known to be complicated by apomixis and polyploidy.

Within Astraea Klotzsch (1841: 194), Astraea lobata (Linnaeus 1753: 1005) Klotzsch (1841: 194) may be considered the most taxonomically complex species due to its wide geographical distribution and the several varieties that have been proposed for this species by Müller Argoviensis (1866, 1874). In his concept, Müller Argoviensis (1866) united under Croton lobatus Linnaeus (1753: 1005) plants with 3–5-partite leaves almost as long as the petioles, subulate stipules, the bracts not well developed and ovaries with varied indumentum. In De Candolles’s Prodromus, Müller Argoviensis (1866) recognized eight varieties, maintaining this concept in the Flora Brasiliensis (Müller Argoviensis 1874) with few modifications. Morphological characters and geographical distribution support the recognition of some of these varieties as species distinct from A. lobata. As part of an undergoing taxonomic revision of Astraea, these distinct taxa must be validly published for further studies on this genus. Therefore, in this note we propose these novelties with commentaries about morphology and geographic distribution, along with photos to illustrate them and lectotypifications when necessary.

The Neotropical genus Himantigera James in James & McFadden, 1982, is revised. Two new species are described and illustrated—H. amauroptera nov. sp. (Costa Rica, Panama, Colombia), and H. xanthopoda nov. sp. (Mexico, Nicaragua, Costa Rica). Three species are transferred from Himantigera to Sargus Fabricius, 1798—S. dichrous (Schiner, 1868) comb. nov., S. flavoniger Lindner, 1928 comb. rev. and S. fulvithorax (Bigot, 1879) comb. nov. One species is transferred to Microchrysa Loew, 1855—M. splendens (Schiner, 1868) comb. nov. Himantigera jamesi Lindner, 1969 syn. nov. is proposed as a junior synonym of H. superba Lindner, 1949. The type species H. silvestris McFadden, 1982, as well as H. nigrifemorata Macquart, 1847 and H. superba Lindner, are herein redescribed and illustrated. Photographs of the type specimens of these three species are provided. Two unnamed species of Himantigera (sp. A and sp. B) are also described given that they have slight differences, but because we had only one specimen of each species, we did not officially describe them. This updates the total number of extant Himantigera from eight sensu Woodley (2001) to seven species. The species Merosargus apicalis Lindner, 1935, although never referred to the genus Himantigera or Himantoloba McFadden 1970, is also transferred to the genus Sargus. A key to all species of Himantigera and a map expanding geographical distribution of the genus are also presented, with the first records of the genus for Nicaragua, Colombia, Venezuela, Trinidad and Tobago, Ecuador and Bolivia.
