Reported from San Miguel, Santa Cruz and Santa Cata- 

 lina. Mrs. Trask records it on San Nicolas as "covering 

 vast numbers of sand-mounds, the bright red flowers con- 

 spicuous." 



22. Abronia umbellata Lam. — This is doubtful as the 

 material is insufficient, the specimen being too young. 

 Reported from all the islands except Santa Catalina. On 

 San Nicolas it covered vast areas of drifted sands. Leaves 

 shining, flowers red and fragrant. 



23. Abronia alba, sp. nov. 



Plate VIII, Figs. 4a and 46. 



Viscid-pubescent ; stems brittle, prostrate or ascending ; leaves orbicular 

 to broadly ovate, obtuse, cuneate at base, sinuate, 1-3 cm. long, 10-16 mm. 

 wide, with petioles equalling or longer than the blades ; heads on slender 

 peduncles 5-7 cm. long, about 12-flowered, with small involucre consisting 

 of five thin, ovate, acute bracts 4 mm. long, 2 mm. wide ; perianth white, 

 very fragrant, with glandular, hirsute tube about i cm. long, and a border 

 6 mm. in diameter, of five divisions, each with two lobes, resembling rabbit's 

 ears ; fruit with ligneous body, at first rhomboidal in outline, becoming 

 cuneate, more or less acuminate at apex, with four unequal wings, each 2 or 

 3 mm. wide above, narrowed to the base. 



This belongs to § I. Abronia of the Bot. Cal. 



It grew in sandy lowlands along the beach, but never on 

 the sand-hills nor the true beach sands as do the other 

 species. It was also less abundant.
