butterfly-shaped, whence the flower in question is 

 termed papilionaceous ; the uppermost and exterior 

 Petal being termed the Standard ( Vexillum, fig. 44), 

 which half embraces the rest, and is in general the 

 largest of all ; the 2 lateral ones are called wings 

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

 which is sometimes divided, or composed of 2 equal 

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

 inserted 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 di- 

 adelphous, fig. 263, 9 of them being united into a 

 tube, cloven lengthwise under the Standard, to whose

 1 are all united into 1 undivided tube, so as to be 

 really monadelphous, fig. 41. Anthers distinct, 

 generally roundish and small; sometimes oblong and

 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 legumin-

 Mimosa tribe'' (Schrankia,WM. Sp.Pl. v. 4. 1041); 

 " sometimes 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
