POLYGONACEAE Lindl. Nat. Syst. Ed. 2, 211. 1836.' 

 Chorizanthe membranacea Benlli. 



No. 8597, collected May 30, on the slopes beyond Hall's 

 valley on the Mt. Hamilton road, where it was found at several 

 ^ ' ices growing in gravel, the slope facing the south. 



Pterostegia drymarioides F. & M. 



No. 8549, collected May 18, on Stevens creek near Soda 

 Rock, Santa Clara county, growing in tangled masses in rich 

 loose soil under shrubs, the leaves quite small. This is a species 

 which occurs under many conditions and in various forms. At 

 Bodega Bay, Sonoma county, the type locality, it grows in pure 

 sand, while at other places it is found in crevices of rocks. 



POKTULACACEAE Reichenb. Consp. 161. 1828. 

 Lininia gypsopliiloides (F. & M.) 



Claytonia gypsophiloides F. & M. Ind. Sem. Petrop. 2 : 33. 

 1835. 



Montia gypsophiloides Howell, Erythea 1: 38. 1893. 



No. 8527, collected May 10, near Smith Creek, Santa Clara 

 county, elevation about 2200 feet, growing in moist places along 

 the roadside. The petals were pink tinged with rose colored 

 veins when fresh, turning pink throughout when dry. In these 

 plants the cauline leaves are rather broad, while in specimens 

 from north of the Bay they are mostly narrow. The type was 

 grown from seed obtained at Fort Ross, Sonoma county. Jepson 

 does not record it from further south than Mt. Diablo. 



No. 8622, collected May 31, at an elevation of 4000 feet, 

 near the summit of Mt. Hamilton, Santa Clara county, on dis- 

 integrating rock on a northerly slope, and not plentiful. These 

 plants are doubtfully referred here, being stouter, more fleshy, 

 more glaucous, the stem leaves very broad and short, and the 

 flowers larger than usual. It is no doubt the plant Jepson men- 

 tions from the summit of Mt. Diablo.
