into a single large common ramified raceme. Each flower is articu- 

 lated at the base on the common rachis. 1 



Telrapleura 2 has the axillary inflorescence and the shortly pedicellate 

 flowers of Stryphnodendron. According to Thonning's description 

 all the parts of the flower are exactly similar to what is known of 

 Entada and Adenanthera. But the pod, which is alone to be studied 

 in our collections, is a peculiar conformation, and suffices to dis- 

 tinguish this genus from the preceding ones. This pod, either 

 straight or bowed, thick coriaceous and indehiscent, bears along its 

 whole length four nearly equal projecting angles or wings; the 

 ventral placentary suture corresponding to one of the intervening 

 furrows. The indefinite seeds are separated by thickenings of the 

 endocarp. The only known species 4 is a lofty tree, from the west 

 of tropical Africa. It is said that its bipinnate leaves are opposite, 

 and that its flowers are grouped in axillary racemes. 



Gagncbind' is easily distinguished from all the preceding genera 

 by characters, which, though very important elsewhere, are here 

 altogether secondary. The floral receptacle is convex, so that the 

 insertion of the perianth and androceum is really hypogynous. The 

 calyx is gamosepalous, five-toothed, and membranous, valvate in the 

 bud. There are five free valvate petals, and ten free stamens witli 

 narrow elongated sagittate introrse two-celled anthers, each 

 crowned by a little glandular swelling. The stipitate ovary con- 

 tains numerous descending subanatropous ovules, in two vertical 

 rows. The fruit is stipitate, oblong, compressed, slightly bowed or 

 sinuous, indehiscent. Its two marginal sutures project distally into 

 membranous wings of sinuous outline. The endocarp grows in 

 between the seeds, including each in a little separate cell. Within 

 the seed coats is a fleshy embryo, surrounded by no great quantity 

 of albumen. The only known species" of this genus is a tree from Mada-
