176 SMITH: STUDIES IN THE GENUS LUPINUS 
The most robust and largest-flowered variety of the species, 
unless equalled by var. palustris; often 60 cm. tall, stem usually 
fistulose ; flowers 15-19 mm. long, banner 15-17 mm. long, rounded 
at the apex, the claw inflated and stiff, sometimes pushing back 
the upper calyx-lip, wings conspicuously truncate at the apex, 
lower calyx-lip strongly subsaccate and bent downward; pods and 
seeds, probably the largest of the. species. 
CALIFORNIA. County not given: 1868-9, Kellogs & Harford 
187 (Type, US 20645). Solano County: near Fairfield, 26 Apr., 
1902, Heller & Brown 5376 (US, G, NY, DS, PA); Gates Canyon, 
mear Vacaville, 27 Apr., 1902, Heller & Brown 5381 (US, PA, G); 
Vallejo, 11 May, 1874, E. L. Greene 171 (G); Wolfskill, 2-6 May, 
1891, W. L. Jepson (UC). Contra Costa County: Muir Station, 
July, 1904, Charlotta Case (UC). Yolo County: Rumsey, 7 May, 
1903, C. F. Baker 3070 (US, G); Woodland, 16 May, 1893, 
J. W. Blankinship (G). Butte County: “fields,” May, 1898, 
Mrs. C. C. Bruce 2033 (NY). Lake County: Burns Valley, Apr., 
1902, Agnes M. Bowman 146 (DS). San Luis Obispo County: 
San Luis Obispo, 27 Apr., 1861, W. H. Brewer 483, Geol. Sur. 
Cal., (US); May, 1893, Mrs. Blochman (UC). 
Two other specimens that perhaps should have been listed 
. above are: Little Oak, Solano County, 2-6 May, 1891, W. L. 
Jepson (UC), and Brighton, Sacramento County, Apr., 1884, K. 
Brandegee (UC). These, and also the Contra Costa plant listed, 
have a much denser pubescence than I have attributed to this 
variety and would probably not be easily traced here by the use of 
the key on pages 171-173. The last-mentioned plant is also a 
pathological individual, having leafy branches and one raceme 
developed from raceme-buds that normally should have produced 
flowers. Seeds with Jepson’s “Little Oak’ specimen are dull 
yellowish brown, finely and sparsely speckled with dark brown, 
6x5 mm., decidedly flattened.
