two are compared. This one lias a flower about 15111111. long, 

 the banner 7 mm. Ipng, 5111111. wide, very slightly notched, un- 

 spotted, .standing well away from thewing.s. The wings are 

 obloiig- oblique and pointed, nearly 3 mm. wide near theba.se, 

 erect unspotted, attached to the keel, which is 2 min. .shorter 

 than the wings, the apex pf the hood purple spotted, not apicu- 

 late.

No. 8599, ■ collected May 30, in Hall's valley on the Mt. 

 Hamilton road, elevation 1500 feet, in a wet meadow in rich 

 black soil. Plentiful and quite large, the stems often two feet 

 long, tangled and interlaced. It was a surpri.se to find this spe- 

 cies at so great a distance from the coast ani at so considerable 

 an elevation. When once known this species is easily recog- 

 nized in the field, variable as it is in growth. About San Fran- 

 cisco (which is perhaps the type locality) as well as about Pacific 

 Grove, where it is abundant, small forms forming a sward occur 

 in places grazed over' by cattle. It sometimes has pale and 

 .sometimes dark flowers, the heads always large. 



ViciA AMERICANA Muhl.; Willd. Sp. PI. 3: 1096. 1803. 

 : -No. 8449, collected April 20, near Lake Merced, in San 



Mateo county, elevation 100 feet, in sandy soil, growing in a 



mass among other vegetation, the stems two feet or more long. 



It has always seemed strange to me that this species, originally 

 ' from Pennsylvania, should also be found on the Pacific slope, 



but the description in the Illustrated Flora shows little difier- 

 5 ence. The leaf in bur plant is narrowed, not "rounded at the 

 Lc base," and the calyx lobes are acute, not blunt or nearly so, as 



shown in the illustration. There may be floral differences, but 



none of our descriptions mention the different parts of the flower, 



.so there is no basis for comparison.
