CORRECTIONS IN NOMENCLATURE. 137 
synonym of Microseris. However, all this having come to 
pass, the names of the few species need readjustment. 
Very unlike Microseris in habit, and enjoying at least two 
good technical characters, namely, the erect heads, and the 
pappus-bristle inserted in a deep notch at summit of the large 
palea, Uropappus is as valid a genus as one can wish for in 
Cichoriaces. It is more clearly distinct from Microseris than 
is Nemoseris from Ptiloria, or even than Hieracium from 
Crepis. The species fall into two subgeneric groups by char- 
acters of the achene and pappus. 
* Achenes brownish; pappus brownish, persistent. 
1. U. Linpieyi (DC.), Nutt. Trans. Am. Phil. Soe. vii. 
425 (1840). Calais Lindleyi, DC. Prodr. vii. 85 (1838); 
Torr & Gray, Fl. ii. 471 (1848), excel. C. lineartfolia. 
2. U.Clevelandi. Calais Clevelandi, Greene, Bull. Calif. 
Acad. ii. 153 (1886): C. Parryi, Greene, l. ¢. 49, but not of 
A. Gray. Probably will include, as an abnormal state, C. 
pluriseta, Greene, Pitt. i. 34. 
3. U. Kelloggii (Greene, Bull. Calif. Acad. ii, 49 (1886), 
sub Calaide). 
4. U. macrochetus (Gray, Pl. Fendl. 112 (1849), sub 
Calaide). 
* * Achenes black; pappus clear white, deciduous. 
5. U. uizartroutus (DC.), Nutt. Trans. Am. Phil. Soe. 
vii. 425 (1840), including U. grandiflorus, l. ce. Calais 
linearifolia, DO. Prodr. vii. 85 (1838). 
Maxacorurrx parvirtora, Benth. Pl. Hartw. 321 (1849): 
M. Clevelandi, Gray, Bot. Calif. i. 433 (1876). From a com- 
parison of the descriptions of Bentham and Gray, there can 
be no doubt they had the same yellow-flowered plant in view; 
and the species is even more common and luxuriant in middle 
California than in San Diego county.
