Widely spread throughout Africa and India, 
This is a weed that has been divided into numerous species, the corolla varying 
much in size and colour, The pollen is oblong-ellipsoid, banded, with 2 stopples, 
and is correctly figured by Lindau in his picture cited.. The description of the 
pellen of the genus Asystasia by me in Dyer, Fl. Trop. Afr. v. 130, is taken 
from other species there included in the genus, and is not correct for A. 
coromandeliana, 
2. A. natalensis (C. B. Clarke) ; branches quadrangular, pubescent ; 
upper internodes 33 in. long; stem-leaves 2 by 4 in. oblong- 
_ lanceolate, obtuse, subsessile ; inflorescence as of A. coromandeliana, 
but much more densely pubescent ; corolla + in. long, rather slender ; 
stamens 4, fertile, subsimilar; anthers oblong, at equal height, 
muticous; pollen subglobose, bands not reaching the pole, stopples 
large ; capsule 4-seeded, on a solid stalk, densely pubescent. 
Eastern Reeion: Natal; without precise locality, Gerrard, 1680! 
The leaves of A. coromandeliana when subsessile are ovate; the present plant 
has Poe pan of Mackaya (not of A. coromandeliana), but the stopples (I believe) 
are 2 only. 
3. A. stenosiphon (C. B. Clarke); nearly glabrous, except the 
corolla ; leaves 21 by 3 in., elongate-triangular, widest close to the 
truncate (sometimes subcordate) base ; petioles 0-1 in. long ; inflores- 
cence, bracts, and calyx nearly as of A. curomandeliana - corolla 1 in. 
in total length ; tube linear, hardly rs in, in diam., funnel-shaped in
