In tins the grooves are wanting, and tlie prominent rib-lilce 

 elevations take Just their places, the intervening parts being; 

 plane or somewhat rugose, not angularly raised. The 

 promptly and completely deciduous pappus is another pecul- 

 iarity. 



9. P. PAXiciJLATl. Stephanomeriapanicidata,l:^\\tt.TYdiiis, 

 Am. Phil. Soc. vii. 428 (18-il)- Plains of the interior, in 

 IdahOj eastern Oregon, etc. And a plant so named by Dr. 

 Gray was collected by myself in extreme northern California 

 in 1370 (No. %3). But this, though otherwise agreeing 

 perfectly with NuttalFs description, has scabro-puberulent 

 acheues ; and specimens matching that iu every respect, save 

 that the branches of the panicle are more virgate, were col- 

 lected on Santa Cruz Tsland. These last are called, but 

 erroneously, "S. virgata'^' in my list of the vegetation of the 

 island. 



10. P. COKONAEIA. Stephanomeria coronaria^ Greenej 

 Bull. Calif. Acad. i. 191 (1885). Santa Lucia Mountains, 

 Calif. Also sent from Monterey Co. by Mr. Hickman. Upon 

 my description of this, Dr. Gray remarked : "by the charac- 

 ter seems too near S. exiguaP ^ But that species has pappus- 

 bristles plumose only above the middle, while in coronaria 

 the plume continues down to the top of the short paleaceous 

 dilatation, at whicli point the plumose part breaks, and falls 

 away, leaving a permanent short crown upon the achene. 

 Nothing at all like this is seen in P. exigiia* 



11. P, EXiGUA. Stephanomeria exigua, Nutt. Trans. Am. 

 PhiL Soc. 1. c. Common in the vast half-desert territories of 

 the Great Interior Basin. Perhaps in southeastern Cali- 

 fornia ; but all the Californian specimens look different, and 

 may belong to P. coronaria or be of a species awaiting recog- 



nition.
