Abstract

Shepherd, K.A., Bennett, E.M., Wilkins, C.F. and Sage, L.W. Lasiopetalum pterocarpum (Malvaceaes.l.: Lasiopetaleae), a new and rare species from south-west Western Australia. Nuytsia 16(1): 175–181(2006). Lasiopetalum pterocarpum E.M. Benn. & K.A. Sheph. sp. nov. is described and illustrated. Thedistinct winged fruit, for which L. pterocarpum is named, is unique within Lasiopetaleae. Lasiopetalumpterocarpum is allied to L. floribundum, which shares a similar habit, large ovate leaves and loosedichasial inflorescences. It can be readily distinguished from L. floribundum by its discolorous andstrongly-lobed leaves, the absence of glandular hairs on the peduncles, and its larger seeds. This speciesis known from only one population south of Perth and is classified as critically endangered.
