lower leaves linear-lanceolate, 6-8 cm. long, about i cm. wide, 

 acutish, somewhat hirsute as well as ciliate, sparingly armed 

 with minute retrorse points, the base hastate rather than auri- 

 cled, the lobes broad and somewhat rounded; upper ones of 

 similar shape but gradually becoming smaller, acute or acumi- 

 nate, glabrous or nearly so: flowering stems naked, about 2 dm. 

 long; pedicels 5-7 mm. long: sepals purplish, over i mm. long, 

 oblong, only the margins white: petals spatulate, slightly longer 

 than the sepals: anthers purplish, a little exserted: silicles 

 round-obovate, 4 mm. across, the margins entire, whitish or 

 purplish, the greenish body somewhat rayed, denseh- tomentose: 

 short style protruding from a slight notch. 



The type is no. 7719, collected April 18, 1905, on the side 

 of a ravine back of Girard station in the Tehachapi mountains, 

 Kern county, California. The species is remarkable for its 

 large, practically entire leaves and tomentose silicles. A rela- 

 tive probably of T. piilchelliis F. & M., but that is described as 

 "siliculis glaberrimis," a fact overlooked by Greene, for in Flora 

 Franciscana, 276, he says "pods densely tomentose."

 No. 7763, collected April 24, in gravel at the foot of the 

 mountain about three miles southwest of Mojave, where it is 

 plentiful. The lower part of the stems and the leaves are grey 

 with very short stellate hairs, and the leaf segments are narrower 

 than in 6". incisa^ the pedicels horizontal instead of ascending, 

 and the seeds red-brown, barely oblong, instead of "linear-oblong, 

 vellow."
