 Bibl. Ind. 17 (1878). Annual, the floating leaves always present, deeply

 what larger, oblong, obcordate at summit : sepals persistent, em])racing 

 the few (4 6) finely and rather sharply rugose achenes; style filiform, 

 deciduous except the base, which remains upon the achene as a short 

 beak. — In early spring only, in winter pools which go dry in summer; 

 frequent in Marin Co. ; also in the Berkeley Hills toward San Pablo. 



6. DELPHINIUM, D/oscom/fs (Larkspur). Erect herbs, with petioled 

 palmately divided leaves, and irregular mostly either blue or scarlet 

 flowers disposed in terminal racemes. Sepals 5. colored and jietaloid, the 

 upper one produced into a long hollow spur, the others plane. Petals 4 

 (or 2 at the least), 2 of them developed backwards into a spur which is 

 inserted into the spur of the calyx. Stamens ao , unequal. Pistils mostly 

 3 (1 — 5), becoming many-seeded follicles.
