many plants from a drier region, well represented in Reed's col- 
lection, are hairy throughout; while others seem quite glabrous, 
They vary too in the form of the foliage and habit of growth, 
but intergrade to such a degree as to render definition by me 
impossible. The desert plant described below seems worthy of 
specific rank. . zs 
wv S. Hallii n.sp. Annual: stems simple, erect, 6 to 9 inches 
high: whole plant pale with an appressed pubescence on leaf and 
toa lesser degree on stem: lower leaves narrowly lanceolate, 3 
lines wide, 1 to 2 inches long, tapering to a narrow petiole; the 
upper leaves sessile, shorter, all firm and entire, or with a very 
few minute and remote teeth, tipped with a dark short mucro, 
not undulate: flowers large, nearly 1 inch wide, petals light yel- 
low with dark spot at base: calyx covered with soft hairs: cap- 
sule pubescent, 4-angled, narrow, 34 inch long, contorted but 
not coiled. d

v S. MICRANTHUM (Hornem.) Walp. is distributed over all 
the maritime regions and in the interior valleys of the south. 
The typical plant of this species is, I presume, the ordinary 
moderately hirsute, semi-prostrate form found from San’ Fran- 
cisco southward. In the coast region round Los Angeles there 
are two well marked forms. One, the congesta form, has very 
congested foliage, with the leaves larger and more hirsute, and 
with very small flowers; the other, the macrocarpa form, with 
the same foliage, has the short stout capsule of dzstorta. The 
latter is the rarer form, examples of which are found from Los 
Angeles, San Diego, and Lower California. A typical interior 
form is found in Parish’s collections from -San Bernardino 
county, and is frequently met with in other interior valleys. It 
is to the eye quite smooth in all its parts.
