XVI. ASYSTASIA, Blume. 
Bracts small, or in A. Schimperi large ; bracteoles minute or 0, or 
in A. Schimperi longer than the calyx. Calyx small, divided to the 
base ; segments 5, equal, linear. Corolla curved, one-sided but not 
(or most obscurely) 2-lipped ; tube long, at the base linear or narrow- 
cylindric, in the upper half much inflated (except in A. stenosiphon) ; 
segments 5, not very unequal; anticous wholly outside in the bud. 
Stamens 4, perfect, subsimilar ; anther-cells oblong or linear, at equal 
height or one a little lower than the other, muticous or minutely 
tailed at the base; pollen oblong or subglobose, with longitudinal 
smooth bands or grooves which reach (or nearly reach) the poles, 
stopples 2 or 3. Ovary with 2 ovules in each cell; stigmas 2, very 
small, subequal, oblong. Capsule 4-seeded at the top on a long solid 
stalk, flattened laterally; seeds flattened, wrinkled or tubereled, 
without hygroscopic hairs. 
Herbs ‘or shrubs; leaves entire, often wavy or irregularly toothed on the 
margin ; inflorescence various. 
Species 35, in the warmer parts of the Old World. 
’ The genus is here defined by the corolla not contorted nor 2-lipped, the 
4 perfect stamens, the capsule 4-seeded at the top. Mackaya is kept separate, 
for convenience, as having only 2 fertile stamens. Lindau has put Mackaya in a 
separate tribe on pollen characters only. The structure of the pollen appears to 
me essentially the same in Asystasia and in Mackaya, the question whether the 
sinooth longitudinal bands reach the pole or not is (for me) not essential, nor 
always easy to see. Moreover, in A. natalensis, A. stenosiphon and others, the 
pollen is that of Mackaya rather than of A. coromandeliana.
