SOME PLANTS OF WESTERN AMERICA 
Several collections of plants from western America have recently been 
submitted to the writer for identification, and among them a number 
have been found of especial interest, either because of their geographical 
distribution or because they represent species which apparently have not 
been described hitherto; these may be recorded and diagnosed as follows: 
ROMANZOFFIA UNALASCHCENSIS Cham. in Nees.-Hor. Phys. Berol. 
72, t. 14, 1820.—Specimens collected on the northeast aspect of vertical 
cliffs, three feet above high sea-level, Albert Head, British Columbia, 6 
June, 1907, Dr. C. F. Newcombe, no. 324 (hb. Field Museum, cat. no. 
250181) correspond in all essential details with a part of the original 
material in the Gray Herbarium on which the above species was founded. 
This station extends the range of the species manera south from 
previously recorded localities. 
Castilleja arachnoidea, n. sp.—Herbacea perennis; caulibus caes- 
pitosis erectis 2-3 dm. altis in partibus inferioribus | crispo-hirsutis, 
superioribus arachnoideo-tomentosis; foliis 15-4 cm. longis linearibus 
vel anguste lanceolatis et integris plerumque trifido, laciniis linearibus 
acutis patentibus, lobo intermedio majore et saepe trifidis; inflorescentiis 
terminalibus dense spicatis to-13 cm. longis; bracteis plerumque trifidis,. 
lobo intermedio integro et obtuso vel apice trilobulato; calyce 15-17 
mm. longo extrinsecus piloso antice et postice subaequaliter fisso; lobis 
lateralibus profunde partitis, laciniis lineare-lanceolatis acutis 7-10 mm. 
longis; corolla 17-20 mm. longa extrinsecus pubescente flava vel lobis 
in sicco paululo rubellis; galea erecta circiter quadruplo brevior quam 
tubus; labium trilobum 5-6 mm. longum; capsula oblonga 10-12 mm. 
longa acuminata acuta glabra. 
On mountain, summits near Marble Mesut, Siskiyou County, Cal., 
altitude’ 2000 m., 6 August, 1908, Geo. D. oe no. 422 (hb. Field Museum, 
. Cat. no. arty 
In general habit this species resembles C. Lemmoni Gray, C. pilosa (Gray) 
Rydb., C. pratensis Heller, and C. oresbia Greenm.; it also approaches C. 
ambigua Jones, but differs in having a shorter corolla and in the nature of the 
pubescence. The arachnoid tomentum, long dense spikes, and conspicuous 
long lower lip of the corolla are the striking characters of the species.
