several erect or sub-erect stems from the same root, covered with a very 

 soft, short, ash-colored pubescence; leaves with very short petioles, ovate, 

 lance-ovate, or lanceolate, obtuse, but slightly mucronate, leafy to the 

 raceme, which is lax and somewhat elongated ; flowers and fruit pendulous; 

 keel naked; wings ovate or obovate, and very slightly ciliolate ; pods oval,

FHANKENIACE^E. 



FRANKENiAf grandifolia, Cham, et Schlecht— Stem usually prostrate, 

 6-12' long, woody or hard at base; leaves 6" long, cuneiform, mucronate;

* Monnina, Ruiz, et Pav. — Sepals unequal, 2 interior large, petaloid and wing-like. Petals 3^. keel 

 concave-galeate, entire or broadly 3-lobed (from the two exterior petals being united with the keel?), 

 free; 2 interior shorter, sub connivent, variously shaped, inserted upon the stamine.il tube. Stamens 8, 

 united in a sheath ; anthers 1-2-celled, opening introrsely by an oblique apicular foramen. Ovary 1-2- 

 eelled; style incurved ; stigma two-lobed at the apex. Fruit indehiscent, 1-2-seeded, either drupaceous, 

 or dry and wingless, or margined with a membranous wing. Seeds estrophiolate, glabrous; albumen

 the pair often united by a membranous, somewhat sheathing base; flowers small, perfect, solitary and 

 sessile iu the forks of the stem, or by the reduction of the upper leaves to bracts becoming cymose-clus-
