NO. 2 gentry: land plants 51 



Known only from the San Benito Islands to which it is apparently 

 confined. The species is related to A. Bar clay ana, but differs in the 

 woody branches, the thicker fruits with less tuberculation on the sides. 

 The shrubby nature of the plant is apparent in the above cited collec- 

 tions. On the sheet of Rempel 361 even the terminal branches are woody, 

 the leaves reduced, while Rempel 366 shows new herbaceous shoots from 

 a thick woody branch, the leaves uncommonly wide and herbaceous, the 

 broad ovate blades 3-4 cm long, mostly 2-2.5 cm wide; petioles 5-10 

 mm long.

Cannery Bay on east side of Cedros Island, March 14, Elmore A37, 

 sandy, rocky soils of alluvial fan. 



Southern California and adjacent islands to Cedros Island; type 

 from San Diego, California. Elmore reports only a few plants observed 

 and the collection consists of a single small plant. I have seen no collec- 

 tions of this species from northern Baja California, but it probably occurs 

 there, since it is a weedy type that is often passed by collectors.
