Heteropogon allionii (Poaceae: Panicoideae) is generally considered as conspecific with H. contortus. Critical studies revealed H. allionii as very distinct taxon which can easily be distinguished from its closely similar taxon, H. contortus by a combination of characters. Hence, H. allionii is reinstated here. A detailed description, illustration and photoplate of both the taxa are provided for easy identification.

Dispersal units, technically seeds, fruits and infructescences equipped with wings for their longdistance dispersal are called winged diaspores. The diversity of flowering plants in South India is noteworthy, and they create a wide range of diaspore morphologies, as evident in their dispersal methods. The present study was carried out to prepare a list of woody angiosperms (both native and introduced) in South India, producing winged diaspores and to analyse their morphological variations, wing formation, and their significance in dispersal. Information from field studies and available literature resulted in a list of 186 species (of which 40 are introduced) which produce winged diaspores, distributed among 26 families in South India. The wings in these diaspores develop from the integument, ovary, perianth whorls or bracts. With a variety of morphology and flight behaviours, they are generally adapted to dispersal by wind, with the exception of a few that are adapted to dispersal by water. The study shows that wings of the diaspores are significant to their survival and distribution.

A taxonomic account on the small grass genus Pseudanthistiria (Hack.) Hook.f. with two species: P. umbellata (Hack.) Hook.f. and P. heteroclita (Roxb.) Hook.f. is provided. Pseudanthistiria burmanica Hook.f. is reduced to the synonymy of P. umbellata. Detailed descriptions, illustrations, conservation status, and a taxonomic key for the identification of the species are provided. Lectotypes for three names, Anthistiria heteroclita Roxb., Pseudanthistiria burmanica Hook.f. and P. hispida Hook.f. are designated.

The grass genus Iseilema Andersson (1856: 250) comprises ca. 20 species distributed all over the world (Clayton & Renvoize 1986, Watson & Dallwitz 1992). Among them, 5 species are known to occur in India (Bor 1960). While studying the genus, we could notice that some species have neither holotype available nor lectotype designated. Lectotypes for three names in the genus are designated here from the available original material following article 9.3 and article 9.12 of the Shenzhen Code (Turland et al. 2017).
