Calyx loosely spreading, colored (yellow) : sepals equal, 

 or the lateral ones somewhat gibbous at the base, linear-lig- 

 ulate, elongated, slightly imbricated in aestivation. Petals 

 scarcely exceeding the calyx, with very long claws, which 

 are connivent, and in S. pinnatifida slightly coherent by the 

 pubescence of their margins into a slender quadrangular tube, 

 in S. integrifolia the glabrous and distinct claws are dilated 

 at the base ; the short and spreading lamina linear or spatu- 

 late, entire. Stamens tetradynamous ; the filaments but 

 little unequal, filiform, elongated and exserted, toothless : 

 anthers linear, spirally revolute when dry. Torus dilated, 

 bearing 2 to 4 large glands. Ovary oblong-linear or linear, 

 raised from the torus on a stipe (gynophore) much longer 

 than itself, two-celled, somewhat flattened contrary to the 

 cells: stigma sessile or nearly so, entire. Ovules numerous, 

 pen'dulous, forming a single row in each cell. 



Siliqjje linear, slender, long-stipitate (the stipe exceeding 

 the pedicel), between terete and quadrangular, the valves 

 carinate with a midnerve : partition nerveless, the areolae 

 (in S. pinnatifida) narrowly linear and elongated, vertical, 

 bounded by even lines. Seeds pendulous, forming a single 

 row in each cell, on filiform free funiculi, oblong or linear-
