PLATYSTEMON AND ITS ALLIES. 147 
Greene Fl. Fr. 282 as to name only. Slender annual 3 to 7 
inches high with narrow-linear tufted leaves and scapiform 
peduncles: corolla 4 in. broad, widely expanding but with 
slightly turbinate base, the obovate yellowish petals being 
somewhat cuneate at base: stamens about 12 or 15; fila- 
ments filiform, much longer than the oblong-linear anthers; 
capsule rhomboid-oval, barely 4 inch long; stigmas ovate- 
lanceolate. 
This species, distinguished from all the others by its fili- 
form filaments, is the rarest of all in collections, being 
known, as far as I can learn, only by specimens of Douglas’ 
collecting—no one knows just where—and by others obtained 
by Mrs. Curran somewhere near Tehachapi in 1884. It 
seems probable that Douglas gathered his in the latitude of 
Tehachapi, to the westward of it, in crossing the elevated 
country, on his journey between Monterey and Santa Barbara. 
While it is not to be doubted that the original material as 
studied by Bentham was of a plant with filiform filaments, 
it is nevertheless evident that Douglas gathered at least one 
specimen of some one of the new species herein proposed ; 
for Asa Gray, in the Torrey & Gray Flora. p. 65, remarks 
that in the specimen in his possession the filaments “ are 
dilated, and linear-oblong or lanceolate, instead of filiform.” 
To which of the species this perhaps single Douglasian 
Specimen with broad filaments may belong is not, however, 
important. 
2. H. arrine. Habit of H. lineare, but peduncles stouter 
and taller, the foliage comparatively short and broad: 
corollas apparently white or cream-color, saucer-shaped, the 
obovate petals not narrowed at base; stamens about 24; fila- 
ments narrowly linear, hardly filiform; stigmas long and 
harrow, lanceolate, even narrowly so, nearly or quite as long
