unci keel bluish, or all the petals blue : keel ciliate : pod 1^^ 3 in. long, 

 8 -12-seeded : seed oblong, little compressed, dark-colored. — Very com- 

 mon in the Bay region, especially on hills not far from the sea ; usually 

 yellow -flowered ; but about Tomales and Bolinas Bays more bble than 

 yellow, just as figured by Lindley under the name L. rirvlaris as the 

 type of that supposed species. Southward, at Santa Barbara, etc., the 

 flowers are wholly of a rather intense blue. Apr. — Aug.
