Abstract 
Forster, P.I. Correction and further notes to ‘Studies on the Australian Asclepiadaceae. I. Brachystelma Simms in 
Australia. Nuytsia 7(2): 123-124 (1990). It is noted that the name Brachystelma glabriflorum (F. Mucll.) Schltr. has priority 
over B . microstemma Schltr. for the single species occurring in Australia, New Guinea and Indonesia. A corrected 
synonymy for this taxon is provided. 
The name Brachystelma Sims is now conserved over Microstemma R. Br. (Brummit 1988). 
The earliest available name in Brachystelma lor ihe single species that occurs in Australia, New 
Guinea and Indonesia is B. glabriflorum (F. Muell.) Schltr. and not B. microstemma Schltr. as 
earlier reported (Forster 1988). B. glabriflorum is based on Microstemma glabriflorum F. Muell. 
from 1858 which has priority over/?, microstemma from 1914. 
The type of Brachystelma papuanum Schltr. is not extant at B and was presumably destroyed in 
World War II. 
The corrected synonymy is given below.
