butterfly-shaped, whence the flower in question is 

 termed papilionaceous ; the uppermost and exterior 

 Petal being termed the Standard (VeJeithttn^ fig. 44), 

 which half embraces the rest, and is in general the 

 largest of all ; the 2 lateral ones are called wings 

 (Ala, fig. 45) ; the lowermost the Keel (Carina, fig. 46), 

 which is sometimes divided, or composed of 2 equal Pe- 

 tals. Stamens 10, fig. 40-42, rarely fewer or more, in- 

 serted into the Calyx beneath the Petals, their Fila- 

 ments either quite distinct, fig. 262, or combined slightly 

 at the very base only, or more frequently diadelphous, 

 fig. 263, 9 of them being united into a tube, cloven 

 lengthwise under the Standard, to whose fissure the 

 tenth is closely applied ; or sometimes the 10 are all 

 united into 1 undivided tube, so as to be really mona- 

 delphous, fig. 41. Anthers distinct, generally roundish 

 and small ; sometimes oblong and incumbent. Gor- 

 men, fig. 47, simple, superior "(often stalked). "Style 

 1 . Stigma 1 . Fruit in a few instances capsular, of 

 1 cell, and generally 1 Seed, either of 2 valves, or 

 none at all; in the greater number leguminous, whence 

 the name of the Order, elongated, of 2 valves, of 3 in 

 Moringa, and of 4 in a few of the Mimosa tribe " 

 (Schrankia, Willd. Sp. PI. v. 4. 1041); "some- 

 times of 1 cell, with 1 or more Seeds ; sometimes of 

 many cells, divided by transverse partitions, the single- 

 seeded cells being occasionally pulpy. The Seeds are 

 inserted into one of the lateral sutures. In those with 

 polypetalous irregular Flowers, the Radicle is bent
