' Stem 1-3 ft.,_tall, quite glabrous, or slightly pubescent near the base. Leaven petioled, 

 pinnatifid or pinnatipartite ; segments remote, spreading, toothed ; terminal large, 

 sometimes hastate. Flowers yellow. Pods li-2 in.,- slender, erect, glabrous, sub-, 

 torulose ; valves 3-nerved ; pedicels J-4 in., ascending, curved. — S. iriomss is said to 

 bjB distinguished by a character that seems to be of no value. All the large flowered 

 specimens resembling and previously referred to S. Irio are referable to S. Lceselii. 

 Boissier's authentic specimen of S. irioides is unique ; its flowers aie described as 

 dpuble the size of those of S. Irio and the style as elongated.
