IO Forms of Phacelia circinata. [ZOE 
local variations; and such is, in fact, the case. Some of these are 
so distinct in appearance, as to be taken as even specifically dif- 
ferent, But on examination it is found that the very nature of 
these differences, based as they are on more important identities, 
forbid such a view, the diverse aspect exhibited by extreme forms 
being due to the degree of development of common characters. 
All the forms are alike in the aggregation of most of the leaves 
in basal clusters; in a pubescence of two kinds, one long and 
strigose, the other short, close and fine; and in floral characters. 
The filaments and styles are much exserted, the former sparsely 
arachnoid on the exserted part, and the latter hispid on the in- 
cluded portion; the appendages of the corolla are joined to the 
base of the filaments so as to form pockets behind them, while 
their united edges form inverted pockets between the filaments; 
the ovary is densely hirsute, and becomes a small (line high) 
acute capsule with alveolate seeds. 
In different forms the stems may vary from a height of one or 
two inches to as many feet, the strigose hairs may quite cover the 
finer pubescence, or both may be scanty, and the cymes and cy- 
mules may be condensed, orelongated and diffuse. The typical leaf 
form is pinnate, with a large ovate or lanceolate terminal lobe, 
and a few small lateral ones at base, but these differ in number 
and shape, or may be suppressed. 
The more pronounced of these forms are perhaps worthy of 
varietal names, but these should be bestowed only after the study 
of very ample material, and the examination of types of the pro- 
posed species that have passed into synonymy. 
The purpose of the present paper is merely to note a few dis- 
tinct forms growing in various parts of Southern California, which 
appear to be fixed in type and exclusively present in the local- 
ities where they occur. All our plants are perennial but farther 
north there are annual or at most biennial forms, which differ in 
no other respect from the perennial ones. 
(a) Stems slender and very unequal, 2-12 inches high, sparse- 
ly leafy, sparsely hispid, the finer pubescence very short; leaves 
lanceolate, 1-2 inches long, all entire, 8-nerved; cymules distant 
and short,
