AND GENERA OF PLANTS. 315 



Grindelia * discoidea; herbaceous, perennial, smooth and resinously punctate ; 

 branches one or two-flowered, fastigiate; leaves oblong-linear, acute, sessile, 

 minutely serrulate; involucrum glutinous; reflected points of the sepals short; 

 flowers discoid; pappus of two setse. 



Hab. On the banks of the Oregon. A genuine species of the present genus, though devoid of 

 rays. Stigmas pointed, pubescent. Capitulum rather small. Leaves about one and a half inches 

 long by two to three lines wide, the serratures very delicate and minute. Stem about a foot high, 

 several from the same root. 



Grindelia *cuneifolia; smooth, leaves entire? cuneate-oblong, obtuse, or 

 linear-oblong, acute, amplexicaule; capitulum sessile, somewhat glutinous, 

 squarrose; stigmas very long, acute, pubescent. 



Hab. St. Barbara, Upper California. Of this I have seen only two small branches, the lower 

 leaves may be different. The capitulum like that of G. glutinosa, of which it is, perhaps, a va- 

 riety. The stigmas very long and exserted. Leaves pellucidly punctate. Pappus of five or 

 more setae. 



HETEROTHECA. (Cassini.) 



Heterotheca * grandi flora; villous and pilose; lower leaves oval, sparingly 

 serrate, petiolate, upper leaves sessile, entire, lanceolate, acute; stem densely 

 pilose below, the summit paniculately corymbose, glandular, as well as the 

 narrow, acute sepals; rays linear; pappus double, the outer dimidiate; achenia 

 obovate-compressed, sericeous. Diplopappus scaber? Hook. Flor. Bor. Am., 



Vol. II., p. 22. 



Hab. On rocks near the sea, round St. Barbara, Upper California. A very showy, large flow- 

 ered species. Stem about eighteen inches high, covered with long, softish hairs, diminishing to- 

 ward the summit, which becomes glandular. Peduncles rather long, and, as well as the narrow 

 linear sepals, clothed with a short, glandular, darkish pubescence. Pappus very copious, bright 

 brown, the outer nearly the same colour, not very distinct; radial achenia naked, triangular, nearly 

 smooth. In the H. scabra the pappus is about half the length of the present, (as is the capitulum,) 

 scarcely half as copious, and the outer, very conspicuous pappus, is silvery white. This plant I 

 have never seen in Oregon or in California. 



CHRYSOPSIS. (Nutt.) 



Chrysopsis Lamar ckii. {Heterotheca Lamar ckii, Cassini. C. divaricata, El- 

 liott.) Certainly no Heterotheca, there existing an uniform double pappus;
