brous ; limb spreading, waved. Stamens unequal, three 
longer than the other two: filaments in part agglutined to_ 
the inner tube of the perianths, but easily separated. Style 
shorter than the filament: stigma incrassated, villous on one— 
side. Achenia obovate, enclosed within the pentangular 
persistent base of the perianth. Embryo conduplicate, 
enclosing within its fold, the small mass of the albumen. 
Dovatas. 
A native of Northern California, extending to N. lat. 46°. 
and to W. longitude 122°. near the great falls of the Co- 
lombia, where it was discovered by Mr. Davin Dovetas. 
It is abundant throughout the dry sandy deserts of the in- 
terior, never growing near the shores of the sea like the two 
hitherto described, Asronia wmbellata and arenaria. The 
blossoms have a powerful honey-like smell in the evening. 
By Mr. Dovetas it was introduced to the garden of the 
Horticultural Society, where it flowered in the summer of 
1828. At present it is very rare: but being easy of culti- 
vation, and thriving luxuriantly in sandy peat, it may be 
= gee, soon to form a valuable addition to our flower-_ 
rders.
