 reticulated on both surfaces, bracts laciniated acutely. 



MOTTLMEIN, on limestone rocks ; Parish. 



Boot tuberous. Leaf solitary, radical, 3 by 2 in., acute not acuminate, hardly 

 serrate, equal at the base, peltate or the auricles only overlapping ; petiole 2-4 in. 

 Peduncle 3 in. with about 10 small flowers ; bracts \ in., persistent, divided to near 

 the base or sharply serrate. MALE: sepals ^elliptic; petals 2, narrow- oblong; 

 stamens about 25, much monadelphous, antn^Pr obovoid, connective not produced. 

 FEMALE: perianth very nearly as in the male; styles 3, combined half-way up, 

 stigmas lunate. Capsule 3-celled, f by in. including the wings, styles persistent, 

 wings 2 short 1 longer, upper margin of each horizontal, dehiscing by all three faces. 

 Seeds short-ellipsoid. 



23. B. moulmeinensis, C. B. Clarke-, stemless, very pubescent 

 throughout, leaves ovate serrate, bracts incise-serrate or laciniate. 



MOULMEIN ; T. Lobb No. 380. 



Closely resembling JB. subperfoliata. The specimens which are in bud differ in 

 pubescence and in the leaf being slightly cordate (not at all peltate), serrate, almost 

 lobed, and not prominently reticulate on either surface. 



24. B. fall ax, A. DC. Prodr. xv. pt. i. 329 ; glabrous or nearly so, leaves 

 elliptic acuminate angular toothed very unequal at the base, capsule equally 3- 

 winged wings narrow their upper margins shortly horizontal. Diploclinium 

 Lindleyanum, Wight Ic. t. 1817. 



South DECCAN PENINSULA ; COUKTALLUM and MALABAR ; Wight. 



The branch figured by Wight is 8 in. long with a peduncle from a lower axil and 

 A. DC. conjectures the plant may be suffrutescent. Leaves 4 by 2 in. ; petiole 1 in. ; 

 stipules oblong, deciduous. Peduncle many times dichotomous, many -flowered, shorter 

 than the leaf; bracts numerous, minute ; flowers medium-sized. MALE: sepals 2, 

 rounded ; petals 2, narrow-elliptic ; stamens numerous, shortly monadelphous, anthers 

 obovoid, connective not produced. FEMALE : perianth-segments 3, 2 large round, 

 1 small narrow lateral ; styles 3, nearly separate, divided half-way up into two curved 

 branches. Capsule - in. long and broad including the wings. Seeds shortly-ellip- 

 soid, somewhat obovoid. Not seen : the above is drawn up from Wight's figure : the 

 plant is of the section Trilobaria if all Wight's details are without error. 



SECT. IV. Flatycentrum. Capsule 2-celled compressed, triquetrous, 

 having one broad and two narrow papery wings ; dehiscing by the falling away 

 of the faces between the wings ; placentas 2-fid.
