Capella Bursa-pastoris Moench. Shepherd's Purse. 

 Common in Strawberry Valley. 



Caulanthus amplexicaulis Wats. 



Onstatt Valley and Chino Creek, at 6500-7500 ft. alt. (Nos. 

 26G0, 2661.) 



Drab a corrugata Wats. 



This rare plant was found to be plentiful around the summit 

 of San Jacinto Mt., where it grows among the rocks in loose, 

 gravelly soil kept moist by lingering snowdi'ifts. It ranges along 

 the west side of the mountain as far as Deer Springs, 9500 ft. 

 alt., and was collected in a canon just below Round Valley, of 

 the east side, at 8800 ft. alt. 



Considerable variation is exhibited in the vegetative characters. 

 The scape-like peduncles sometimes arise from a rosette of leaves 

 each of which measures only 3 or 4 lines long; in other speci- 

 mens growing in the same locality, but probably in more 

 sheltered positions, the leafy, branching stems are several inches 

 high and the leaves li in. long. In technical characters our 

 specimens agree well with the co-types of D. corrugata with 

 which they were compared. (Nos. 703, 2413, 2499.)

Common from the lower edge of the pines to 9500 ft. alt.

The Santa Rosa Indians mix the seed of this plant with their 



corn meal to give it a more agreeable flavor.
