2. SECUEJDACA, Linn. ; Bentli. et Hook. f. Gen. PI. i. 138. 



Flowers irregular. Sepals 5, unequal, two (wing-sepals) much larger, 

 petaloid and wing-like. Petals 3, distinct from each other, adnate helow to 

 the sheath of stamens, median petal (carina) galeate ; if 5 petals the 2 upper 

 squamiform and rudimentary. Stamens 8, monadelphous, the sheath split 

 above and adherent at the base to the petals ; anthers 2-celled, dehiscing by 

 a triangular recurved valve in front. Ovary 1-celled (one cell being abor- 

 tive), with 1 ovule. Style oblique, incurved above. Fruit a samara. Seed 

 estrophiolate, glabrous, exalbuminous. — Shrubs usually scandent, or small 

 trees. Leaves alternate, entire. Flowers in terminal and axillary racemes or 

 panicles. 



A considerable genus in Tropical America, represented by few species in the Old Worm 

 and but by two in Africa, one of which is widely distributed and very variable. 



Branches pubescent. Leaves more or less oblong, obtuse, rarely 



exceeding 1-2 in. by A-J in. Flowers in racemes . . . . 1. S. longipedunculata.

 margin more or less revolute when dry, glabrous or glabrescent, paler and 

 venation usually obscure beneath, f-2 in. long, i-f in. broad; petiole 1-^
