Var. hebecarpa. Capsule villous. —W. Australia ? Herb. Hooker. 
the short diagnosis given is insufficient to distinguish it either from O. multiflorus or 
O. Muelleri, Benth. A small slender species, the stems rarely 
1 ft. high, glabrous or slightly woolly towards the base. Leaves 
shorter than the stems, 1 to 14 lines broad, woolly on the keel and. 
inner margin when young. Spikes 2 to 4 on the stem, all pedunculate 
or the lower one sessile, resembling those of O. multiflorus in the brown 
scarious apices of the bracts, but rather smaller. Flowers usually 3 or 
4inthe spike. Capsule obtuse, not longer than the bracts.
