New or Noteworthy Plant Collections from Myanmar (2) Aponogeton lakhonensis, Cryptocoryne cruddasiana, C. crispatula var. balansae and Stichoneuron membranaceum

Abstract

In the course of floristic research of Myanmar, some noteworthy monocots; Aponogeton lakhonensis A. Camus (Aponogetonaceae), Cryptocoryne cruddasiana Prain, C. crispatula Engler var. balansae (Gagnep.) N. Jacobsen (Araceae), Stichoneuron membranaceum Hook. f. (Stemonaceae), were collected. Of these Cryptocoryne cruddasiana, endemic to upper Myanmar, was recollected in Kachin State (the northernmost state in the country) after an interval of more than half a century. Other taxa are new to the flora of Myanmar. These materials may also be significant in clarifying the floristic elements of Myanmar and their relationship with those of neighboring regions.
