28o Miihlenbergia,' Volume 2 



pointed, the one very slightly longer than the other: flowers not 

 present in the type, but small, white, little surpassing the calyx, 

 as noted on the living plant: capsule nearly globose, straw col- 

 ored, shining, practically as long as the calyx, but included: 

 seeds very small, less than i mm. in diameter, turgid lenticular, 

 black and shinirg. minutely roughened, and under a good lens 

 showing a distinct rim. 



The type, in my herbarium, is no. 8501, collected May i, 

 1907, near Pacific Grove, Monterey county, California, growing 

 in a cleared place in sandy pine woods, and plentiful. 



There are two specimens of this plant in the herbarium of 

 the University of California, one collected June 6, 1893 at Pacific 

 Grove by Ivar Tidestrom, the other at Belmont, San Mateo 

 county, by J. Burtt Davy, no. 793, June 17, 1893. 



It is one of the forms referred to Claytonia or Montia per- 

 foliata^ but is easily segregated from all the others by its color, 

 which seems to be characteristic, by its elongated lax umbellate 

 inflorescence, and by the small seeds.

Cerastium patulum Greene, Pittonia 4: 302. 1901. 



No. 8446, collected April 20, near Lake Merced, San Mateo 

 county, elevation about 400 feet, growing on moist northerly 

 slopes in a tangled mass of other vegetation. The sepals are 

 hardly "very broad, obtusish," as they are about 2 mm. wide, 

 bluntly pointed, only plainly i-nerved instead of "strongly 3- 

 nerved." The type was from "stony hills about Sa'n Francisco 

 and elsewhere in middle California near the sea."
