Common along the shores of the tropics and subtropics of the Old 

 and New Worlds ; type from Curacao, Dutch West Indies. The above 

 collections established the plant as general in distribution along the 

 saline littoral of the southern half of the California peninsula. 



Caryophyllaceae 



Drymaria holosteoides Benth., Bot. Voy. Sulph. 16. 1844. 



San Francisco Island, March 9, Rempel 108, edge of playa. San 

 Gabriel Bay, Espiritu Santo Island, March 7, Rempel 100, transition 

 between beach dunes and alluvial flats. Los Angeles Bay, March 19, 20, 

 Rempel 260, north end. 



Sandy soils from central Baja California to the Cape District and 

 the surrounding islands. It is one of the most common low winter an- 

 nuals in the middle peninsula where it affects the arid gravelly soils as 

 well as the sands of alluvial fills and dunes. The type locality was er- 

 roneously given as Cape San Lucas, but it is most likely Magdalena Bay, 

 where Barclay and Hinds collected it (Wiggins, Proc. Calif. Acad. Sci. 

 IV, 25:194. 1944). 



Drymaria peninsularis Blake, Jour. Wash. Acad. Sci. 14:285.

San Jose del Cabo, February 17, Dawson 1189. 



Endemic to the postinsular Cape District. A diffuse stipitate-glandu- 

 lar annual 15 to 18 cm tall with thickish linear leaves. A close examina- 

 tion of the petals shows the appendages in the sinuses to be variable. 

 They may consist of one forked ligulate appendage, or 2 to 3 lobes of 

 varying width, some of which are nearly subulate, and which, according 

 to Wiggins (1. c. p. 203, pi. 22), separates the peninsular species from 

 the mainland D. arenarioides. Hence, in the Dawson specimens, this 

 floral character separating the two species is not consistent, and suggests 

 that typical D. arenarioides may exist on the peninsula, although it has 

 never been collected there, and the Dawson specimen is an intergrading 

 or hybrid form. If this should prove to be the case, then D. peninsularis 

 had better be regarded as a variety of D. arenarioides. 



Drymaria polystachya diffusa (Rose) Wiggins, Proc. Calif,
