1. BOWLESIA E. & P. 



Delicate annuals with stellate pubescence, opposite simple leaves and scarious 

 lacerate stipules. Umbels simple, few-flowered, on short axillary peduncles. 

 Flowers white, minute. Calyx-teeth prominent. Fruit ovate, somewhat flattened 

 laterally, with narrow commissure; carpels turgid, becoming depressed on the 

 back. Eibs and oil-tubes none. (Wm. Bowles, 1705-1780, Irish naturalist and 

 traveler.) 



1. B. lobata R. & P. Stems mostly branching at the base, weak and 

 trailing. i/> to 2 ft. long, flowering from the base; leaves thin, mostly 5-lobed, 

 broader than long, usually heart-shaped at base, the lobes entire or some of them 

 1 or 2-toothed, y% to 1 in. broad; petioles 1 to 3 in. long or the upper shorter; 

 umbels 1 to 4-flowered; fruit 1 line long. 



Shaded places in the hills: Coast Ranges ( Petaluma, Berkeley, San Fran- 

 cisco) ; Sierra Nevada to Southern California, eastward to Arizona and 

 Texas. Coulter and Rose have named the North American plant B. septen- 

 trionalis (Mong. Umbel., p. 31). Our plants may well be distinct from any 

 South American forms and if so the distinction is susceptible of expres- 

 sion in terms of plant structure as well as of geography.
