Simple or loosely branched from near the base, loosely short 
villous; whorls usually two to five, crowded or distinct; flowers 
spreading in anthesis, soon becoming suberect, about 12 mm. long; 
calyx retrorse-villous below with hairs 1-1.5 mm. long, the lower 
lip with a vestigial median tooth; petals reddish purple or paler, 
the banner about 10 x 6 mm., angled at the apex; seeds 5 x 4 mm., 
somewhat flattened and angled, dark-gray, minutely dotted with 
black, paler about the hilum, the entire surface minutely roughened, 
resembling quartz. 
CALIFORNIA. Santa Clara County: Mt. Hamilton road, 
2300 ft. alt., ‘‘on a roadside bank near oak trees,”’ 31 May, 1907, 
A. A. Heller 8652 (Typr, US 612641; type-duplicates, PA, NY, 
G); seed only, type locality proper, 17 June, 1908, C. P. Smith 
(CPS); tilled soil below Smith Creek bridge, 17 June, 1908, C. P. 
Smith 1479; Calaveras Valley, May, 1914, K. Brandegee (UC 
178195, except as to raceme in upper left hand corner). 
This seemingly well-marked variety may be peculiar to the 
Mt. Hamilton Range. The plants are low and mainly simple in 
poor soil, but in richer and looser soil may be 2-3 dm. tall with a 
spread of 3-4 dm. The Smith Creek specimens were in seed as 
to the primary branches, while secondary branches, in the axils 
of the primary branches, were in flower.
