gtowing in dense colonies. A tall handsome species, whose oc- 

 currence in this region was not expected, although I found it on 

 the east side of the Sierras at Donner lake in 1903. The type 

 came from the west side of the Sierras, from the "Wawona and 

 Yoseiltite region generally.

No. 8427, collected July 31, in the sand hills along the 

 railroad about two miles northeast of Del Monte, Monterey 

 county. Abundant, the flowers cream colored instead of "pur- 

 plish," as described in the Synoptical Fora, although some of 

 them darken in drying. The retuse tips of the upper and floral 

 leaves are not much in evidence, neither is the character of 

 "hispid- or setose-ci Hate bracts and floral leaves" well marked. 



Orthocarpus purpurascens Benth. 



No. 8381, collected June 8, in San Mateo county, near 

 Ocean View, San Francisco, on the Lake Merced side of the 

 Ocean Shore tracks in sandy soil. This is the form with pale 

 lavender bracts, and whether it is the typical form I do not 

 know. The species as at present received is evidently an aggre- 

 gate. \^rV^-li.-.
