168 POLEMOXIAGEAE 



Sandy flats in the valleys or gravelly slopes in the hills, 1400 to 2000 feet : Lake 

 Co. ; Santa Cruz Mts. June. 



Geog. note. — Hugelia abramsii is an endemic of the central Coast Range region limited to 

 two narrow areas, one in Lake Co. and the other in the Santa Cruz Mts. The plant in the field has 

 a distinctiTe aspect in the intense green of its narrowly divided bracts which contrast curiously 

 with the white matted wool of the heads. The known stations are as follows. — Lake Co.: Cold- 

 stream, Curran; betw. Burns Valley and Borax Lake, Hoover 3554; Mt. Konocti, BlanMnsliip. 

 Santa Cruz Mts.: Emerald Lake, San Mateo Co., L. S. Eose; Black Mt., Santa Clara Co., Pendle- 

 ton 137. 



The long and narrow capsules of this species have been noted by Virginia L. Bailey. This 

 feature is similar to the capsules in Hugelia virgata. No species of Navarretia vrith S-celled 

 capsules possesses capsules that are so narrow and so long. Tlie character of the woolly heads is 

 rather that of Hugelia than of Navarretia, where this species has formerly rested. Its seed-coats 

 are also mucilaginous under water as in other Hugelia species.

6. COLLOMIA Nutt. 



Herbs with alternate leaves. Flowers in ours in dense clusters with foliaceous 

 bracts. Calyx turbinate, in age obpyraniidal or cup-shaped, its teeth or lobes equal, 

 entire, erect, the sinuses in age distended at base into an outwardly-projecting fold. 

 Corolla narrowly funnelform or salverform, salmon-yellow, reddish, purple, blue 

 or white. Stamens usually unequal, unequally or equally inserted on the corolla- 

 throat, mostly straight. Seeds 1 in each ceU (sometimes 2 or 3) , the seed-coat often 

 developing spiral threads when wet. Capsule oval to obovoid. — Sj^ecies about 18, 

 western North America and Chile. (Greek kolla, glue, on account of the mucilagi- 

 nous seeds.)
