Adenostegia pilosa var. Bolanderi Greene, Pittonia 2: 180. 1891. 
Adenostegia Bolanderi Kuntze, Rev. Gen. 2: 456. 1891. 
Slender, paniculately branching annual, 2-6 dm. high; stems 
puberulent with short, scattered, glandular, pilose hairs, sometimes 
glabrous; leaves 1-3 cm. long linear, occasionally with callous tips; 
flowers scattered along the branches; floral bracts 12-20 mm. long, 
puberulent, ciliate with glandular, pilose hairs, linear-lanceolate, 
entirely herbaceous or with callous tips; calyx-leaves with pubes- 
cence as on bracts, the upper 15-18 mm. long, three-nerved, 
lanceolate, sometimes bidentate, the lower 14-18 mm. long, five- 
nerved, broadly lanceolate; corolla 12—1 5 mm. long, the tube 
about equalling the throat, inconspicuously hairy; capsule 8 mm. 
long; seeds few, somewhat reticulated. [PLATE 10, FIG. 5.] 
The glabrous or puberulent type of A. tenuis is found in the 
Lake Tahoe region and in western Nevada, while the form de- 
scribed as A. pilosa var. Bolanderi is characteristic of the mountain 
ranges north of this region. This last-named form was described 
by Gray as being more nearly related to A. pilosa, but an examina- 
tion of co-type material shows that the bracts are not notched as 
they are in A. pilosa and that in the pubescence it is like A. tenuis 
except for the presence of scattered, pilose hairs. 
The specimens from Lake County are like the Nevada form, 
_ while those from the Kings River region more closely resemble A. 
pilosa. j
