Plant of the Month — March 2014
Acacia cyclocarpa is most closely related to A. trachycarpa which is common in the Pilbara region c. 1,000 km south-west of A. cyclocarpa. It is distinguished from A. trachycarpa by its low sprawling growth form, broader pods and larger seeds.
A. cyclocarpa is a Priority Three taxon originally listed under the name A. sp. Pitta Creek (M.D. Barrett 1840).
The specific epithet is derived from the Greek kyklos (Latin cyclus), a circle or ring, and karpos, a fruit, in allusion to the pods which are prominently curved into an open circle or coil. The suggested common name is “Ring-pod Minni Ritchi”. A. cyclocarpa was described by Bruce Maslin, Matthew Barrett and Russell Barrett in our journal Nuytsia, from which much of this text is transcribed. This paper includes detailed taxonomic of a further 12 newly described taxa from the north-western Kimberley area of Western Australia.
