Lectotypification of names in the genus Eragrostis Wolf (Poaceae)
In the present work 3 names within the genus Eragrostis viz, Eragrostis coarctata, E. plana and E. superba have been typified. Lectotypification has been performed for E. coarctata and Second-step lectotypification has been done for the names E. plana and E. superba. For lectotypification, rules and recommendations proposed by the International Code of Nomenclature for algae, fungi and plants (ICN), have been strictly followed. The selection of lectotypes are explained and the images of selected lectotypes are provided
Typification and taxonomic notes on species of Muhlenbergia Schreb. (Poaceae, Muhlenbergiinae) in India
The present paper deals with typification for two names in the genus Muhlenbergia i.e. M. duthieana and M. himalayensis. Furthermore, taxonomy of all Indian species for the same has been provided along with taxonomic key for correct identification
Notes on the typification of three names in the genus Arundinella Raddi (Poaceae)
In the present study, lectotypes for three names in the genus Arundinella Raddi are designated. Lectotypification of A. intricata and second-step lectotypification of A. laxiflora and A. mesophylla has been done. Additionally, the geographic distribution of endemic species, A. mesophylla is also provided
An update on the taxonomy of Calamagrostis nagarum (Bor) G.Singh and its allies (Poaceae, Agrostidinae): morphometrics and micro-morphology
Calamagrostis nagarum, previously considered to be a poorly known species, has been reassessed taxonomically. It is a member of C. lahulensis-C. scabrescens complex and may be segregated by morphological characters such as the presence of pilose hairs on adaxial surface of leaf blades, spreading panicle branches, filiform awn and nerve prolongation of lemma. Besides, the micromorphology of adaxial surface of leaf blades, dorsal surface of glume and lemma differentiates Calamagrostis nagarum from its allies, C. lahulensis and C. scabrescens. It is known from Nagaland and Uttarakhand, India, and Bhutan. In this study, we have provided an emended description of the species, a discussion of its habitat and distribution, and taxonomic notes along with field photographs and photo plates for its correct identification. In addition, we also lectotypify the names C. lahulensis and C. scabrescens
