No 8576, collected May 28, above Crystal vSpritij^s, San Ma- 

 teo county, near the Half Moon Bay road, elevation 425 feet, on 

 an open grassy slope. This is from the type locality of C. caes- 

 pitosa^ and seems to be the only known station for the plant. 

 This species has been misunderstood by all except Greene in his 

 Manual, 178, and Jepson in his Flora, 565, since the time of 

 Torrey and Gray's F'lora. I am informed by Professor Jepson 

 that he has seen the type, and that C. caespitosa is identical. 

 The plant grows in dense tufts, the stems four to eight inches 

 long, slightly woody at the very base, prostrate or decumbent, 

 the large violet-purple heads solitary on scape-like peduncles.

No. 8455, collected in San Mateo county on the sea shore 

 where the Ocean Shore railroad appears on the coast, growing 

 in sand. It is a strictly maritime species, always found within 

 reach of the salt spray. The original was thought to have come 

 from Buenos Ay res.

No. 8575, collected May 28, above Crystal Springs, San 

 Mateo county, on the Half Moon Bay road, elevation 425 feet, 

 in grassv fields. The determination is by no means certain, as 

 the genus is badly in need of revision. Some of the achenes 

 have four pappus awns, and perhaps that is the normal number, 

 as the\' break off readily.
