This plant, in common with many others that have a range 
which extends from north-central to extreme-southern California 
occurs in two forms, one, confined largely to the coastal region 
and characterized by very unequal obovate sepals and the other, 
largely belonging to the interior valleys, characterized by less 
unequal linear-lanceolate or narrowly oblanceolate sepals. In 
general distinct enough these forms merge, especially in the central 
part of the state where specimens have been secured which are so 
intermediate in character that they directly connect the typical or 
coastal form of the species and the variety australis, i. e. the form 
of the interior with relatively narrow sepals. The type of P. distans 
came from Bodega Point and two leaf forms grow in that vicinity, 
one having simply pinnatifid leaves and one bipinnatifid. Brand 
in his revision described the former leaf-form as variety australis 
but based it on specimens from interior southern California, evi- 
dently having seen only the typical form from the type locality. 
It is impossible, however, to distinguish satisfactorily in this group 
of species varieties based only on degree of leaf-division because 
the variation in this respect is so great. On the other hand it is 
entirely practicable and also desirable to indicate by name the 
calyx-variation discussed above because its occurrence is corre- 
lated with a range-difference that is noteworthy. Accordingly it 
seems to me that the proper treatment of the variety australis 
Brand is to interpret it to include the plant of the interior of the 
state irrespective of the relative deepness to which the leaflets are 
cut since this obviously superficial variation belongs equally to the 
typical form of the coast. In accord with this view the var. am- 
mophila (Greene) Brand becomes a synonym of the var. australis 
Brand.
