 Su/c.tdorf. A common and variable species, with the attenuate pods, simple stigma, and 

 often purjilish flowers of this genus, but included by many and with almost equal propriety 

 in Sisijmbriiim. 



Var. rigidum, Robinson, n. var. Foliage and flowers as in type : pods deflexed but 

 widely spreading, curved outwards, very rigid and pungent. — T. rigidum, Greene, Pitttjiiia,

 similar habit, has shorter inflorescences, less numerous pods of le.ss rigid texture, somewhat 

 larger flowers and stigmas almost iUways slightly 2-lobed. witli lobes lying over the pla-

 somewhat smaller: sepals narrowly oblong, H, to 2 lines in length, widely .spreading, not 

 gi-eatly exceeded by the narrow although flat jietals : fruiting pedicels short, curved
