A New Species of Tupistra (Asparagaceae) from Laos

Abstract

Tupistra laotica N. Tanaka, a new species from Laos, is diagnosed, described and illustrated. It is unique in having a remarkably long slender peduncle and small broadly campanulate flowers with deltoid tepals and a patelliform or cupulate stigma. Diagnostic differences from two other congeners, T. stoliczkana Kurz and T. muricata (Gagnep.) N. Tanaka, are noted.
