Fig. 32. B. subperfoliata, Parish. Capsule dehiscing round an elliptic line on 

 each face. 



33. B. gigantea, Wall. a. Capsule, dehiscing along a narrow ellipse on 



the face between the narrow wings only ; the other faces indehis- 

 cent ; the elliptic piece splits out elastically from the base, carrying 

 the placenta; with it. b. Horizontal section of the dehiscing cap- 

 sule ; plan© passing through the line * c. Similar horizontal 



section of the capsule made just before dehiscence ; placentae shown, 

 seeds not shown, d. Seed, brown -yellow, X 25 diatn. 



34. B. episcopalis, C. B. Clarke, a. Capsule, dehiscing by a narrow elliptic 



line on the face between the narrow wings only, the elliptic piece 

 not yet split out. b. Horizontal section of the dehiscing capsule ; 

 plane passing through the line * . . . . 



35. B. xanthina, Hook. a. Capsule, dehiscing along a narrow ellipse on 



the face between the two shorter wings only. b. Horizontal section 

 of the capsule ; plane passing through the line *....; placenta? 

 shown, seeds not shown. 

 3G. B. rubro-venia, Hook. a. Capsule, dehiscing along a narrow ellipse on 

 the face between the two shorter wings, and also simultaneously by 

 a single line on each of the other faces close to the narrow wing. 

 b. Horizontal section of the capsule ; placentas shown, seeds not 

 shown. Ultimately the two lateral faces dehisce completely ; not 

 being attached by the septa they flake out as at c, which is the same 

 horizontal section as b in the latest stage, d. Seed, yellow-brown, 

 X 25 diam. 



37. B. laciniata, Koxb. Capsule dehiscing ; dehiscence exactly as in B. 



rubro-venia. 



38. B. brevicaulis, A. DC. From A. DCs type specimen. Capsule de- 



hiscing just as in laciniata. 



N.B. All the capsules between 51. laciniata and 59. brevicaulis are 

 like laciniata or rubro-venia, differing a little in shape and hairiness. 



39. B. integrifolia, Dalz. Capsule, dehiscing exactly as in B. rubro-venia, 



&c. 



40. B. goniotis, C. B. Clarke. Capsule, dehiscing as in B. rubro-venia. 



41. B. sandalifolia, C. B. Clarke. Capsule, dehiscing as in B. rubro-venia.
