Petals strap-shaped, truncate, or slightly notched at the apex. 
Filaments not winged, but the shorter ones with 2 long setaceous 
processes at the base. Pod sub-orbicular, notched at “the apex ; 
style not exceeding the depth of the notch; valves convex in the 
centre, depressed all round the margin, without a dorsal nerve.

down, and having long woolly hairs at the summit remaining until

each with a pair of appendages resembling barren filaments spring-
