XXVII. N. G. Darwinia. Calyx 5 clentatus, corolla 
papilionacea, carina unicalcarata, calcar subula- 
turn, staminib. 10 diadelphis, ieguminibus longis- 
simis linearis angustis planis poiyspermis, semi*- 
nibus oblongis.—-Obs. This genus differs from 
Indigofera by not having a double spur, nor a 
round pod. I dedicate it to the celebrated Dar¬ 
win, who ought to have already received such an 
honour from his countrymen ; but should any 
genus have lately and previously been named 
after him, unknown to me, then I propose to 
substitute thereto the name of Motioplectra.
