40 [96] BOTANY. 
HogMsIstERIA PLURISETA (sp. nov.): fruticulosa, puberula; foliis oppositis et alternis parvis 
plerumque hastato-trifidis inciso-dentatis ; involucri squamis floribusque 20-25 ; pappi paleis 
10-12 lineari-lanceolatis (aut muticis aut partim acuminato-aristatis,) cum setis totidem tenuibus 
denticulatis. (Tab. IX.) Ina cafion at Bill Williams’ fork, now called Williams’ river; February 
This is evidently a congener of Helogyne fasciculata, Benth., of southern California, and appa- 
rently of Phania? urenifolia, Hook. & Arn. also, although the number of scales and awns of 
the pappus (2-3 in the former and 4-5 in the latter) is thrice or twice greater. On account of 
the earlier Helogyne of Nuttall, (founded on an obscure Eupatoriaceous plant from Peru, but 
apparently with good characters,) the late Dr. Walpers has changed the name of Bentham’s 
genus to Hofmeisteria, in honor of one of the best phytotomists of the age. This genus, 
strengthened by a third species, is well marked in habit as well as character. All have 
palmately-lobed or divided leaves on very long petioles. In H. pluriseta the petioles are an 
inch or an inch and a half long, while the blade is only 4 to 6 lines long. The latter is ovate 
or deltoid in outline, and irregularly cut into 3-6 coarse teeth or lobes, the two basal ones 
usually largest and divergent. Involucre as in Brickellia; the scales acuminate. Corolla 
ochroleucous ; the slightly dilated summit 5-toothed. Style, &c., as in H. fasciculata. Achenia 
oblong, nearly terete, 5-ribbed, minutely hirsute. Palez of the pappus 10 or 12, hyaline, with - 
somewhat erose margins, entire at the summit, which is either obtuse, retuse, or several of them 
more commonly produced into an acuminate point, or into a short awn, the latter above half the 
length of the achenium. Bristles. of the pappus as many as the palez, and alternate with them, 
forming an inner series as long as the corolla, nearly capillary, minutely denticulate.

Bricketira Catrrorntca, var. Gray, Pl. Fendl. p. 64. Rocky hills and plains on the San

leaves, and smaller heads indicate it-as probably distinct from B. Californica ; and it is very 
likely to pass into B. Wrightii.
