120 ERYTHEA. 
Plentiful on the plains of Shasta River, Siskiyou Co., 
Calif., apparently collected only by the present writer, in 
1876. Both this and the preceding are of the Machewran- 
thera subgenus. 
Linanthus serrulatus. Freely and almost diffusely 
branching, 6 or 8 inches high, green and seemingly glabrous 
but the branches pubescent: leaf-segments and floral bracts 
all linear-acerose, glabrous, but the margins spinulose- 
serrate; calyx-segments more than twice the length of the 
tube, remotely serrate-ciliolate: corolla with slender dark- 
purple not far exserted tube, and narrowly funnelform throat, 
the limb of oblong-spatulate white segments expanding to 
the diameter of # inch. 
Near Madera, California, 1889, Mr. Buckminster. 
Linanthus montanus. JL. ciliatus, var. montanus, 
Greene, Pitt. ii. 260. Habit of ZL. ciliatus but larger, leas 
hispid: corolla many times larger, nearly 2 inches long, with 
elongated tube gradually widening to a broadly funnelform 
purple throat, the limb of cuneate-obovate truncate whitish 
segments 4 inch broad, yet apparently expanding not to the 
rotate, but only to the wide-funnelform. 
Common at middle altitudes of the Sierra Nevada from 
Nevada Co., southward to the San Bernardino Mountains, 
from which southern station Mr. Parish has distributed it 
for L. androsaceus, to which it is not intimately related. 
Linanthus nudatus. Slender, 3 to 10 inches high, with 
few and divergent branches; lower internodes not exceeding 
the short (4 inch long) leaves, the upper 14 to 3 inches long 
or more: branches puberulent: ordinary leaf-segments 
hispidulous-ciliate, the floral villous-ciliate: calyx scarious 
between the angles, the segments hirsute-ciliate: corolla with 
very slender long-exserted tube, short yellow throat, and 
white or purplish limb 4 inch broad. 
Probably common in Lake County, California. Well 
marked by its short foliage, long naked internodes and 
dense clusters of small flowers.
