Eriodictyon californicum var. pubens Brand, loc. cit. 
Eriodictyon glutinosum var. intermedium Parish, Brand, loc. cit., published as 
a synonym. 
Low shrub o.5-1.5m. high, with the erect branches and 
branchlets glabrous or nearly so and glutinous: leaves broadly 
lanceolate to linear-lanceolate, 5-10 cm. long, 1-3 cm. wide, firm 
coriaceous, flat and dentate or sometimes slightly revolute, glabrous 
and glutinous on the upper surfaces, paler beneath with a close 
fine tomentum within the conspicuous reticulations: branches 
of the inflorescence pubescent: calyx densely pubescent, nearly 
equaling the corolla tube: corolla 5-6 mm. long, its tube funnel- 
form, white, densely pubescent without. 
This species was first described by GRAY as a variety of angustifolium, but 
afterward (4) considered by him as one of the intermediate forms between that 
species and californicum. BRAND, basing the distinction mainly on the rela- 
tive length of the free and adherent parts of the filaments, considered it as a 
variety of californicum, and restored angustifolium to specific rank. That the 
species is closely related to both angustifolium and californicum is evident, but 
the tendency to 5 Depa eld nas is not through intergradation with 
typical californicum, but w' ifolium nigrescens. It is through this variety 
that all three of the species, californicum, crassifolium, and trichocalyx, form 
almost a complete series of intergradations. With this as the status of these 
forms, as demonstrated now by a large series of specimens, there are two 
ways of expressing their relationship taxonomically, either crassifolium, 
trichocalyx, and californicum should be considered as strains of a single 
species, or each should be given specific rank, and their more extreme geo- 
graphical forms varietal rank, admitting that they do have a tendency to 
intergrade in contiguous territory. We have chosen the latter course because 
relationship can be shown sufficiently accurate by the simple binomial and 
trinomial method without the introduction of such burdensome combinations 
as Eriodictyon californicum australe pubens coarctatum Brand. Such combina- 
tions are as cumbersome as the pre-Linnaean system and less significant, for 
they need not be in any way descriptive.
