SPECIES OF ZAUSCHNERIA. 97 
vation of the plants. Species with a peculiar!y strict, virgate- 
elongated inflorescence, and a good seed character. The pu- 
bescence that of the third species. 
* * Leaves with no trace of feather-veins : plants 2—5 feet 
high. 
3. Z. CALIFORNICA, Presl. Erect from the base and not 
" branching : pubescence tomentose, less dense than in the last, 
and with some hirsute hairs: leaves linear or linear-lanceo- 
late, entire or denticulate toward the apex: petals exceeding 
the calyx-segments, stamens little exserted: capsule nearly 
glabrous, distinctly pedicelled.—Rel. Heenk. ii. 28. t. 52: Z. 
Californica, var. microphylla, Gray in Bot. Cal. 1. e. ? 
Habitat as indicated under No. l. There is every reason 
for thinking that the plant of the southern part of California, 
which Dr. Gray had named var. microphylla, is the typical Z. 
Californica. Both the character gives and the habitat point 
to that conclusion ; and since at Cambridge they have always 
called the more common and widely dispersed Z. latifolia, Z. 
Californica, it may have seemed needful to give the very dif- 
ferent appearing plant of the southern coast (which is the 
original plant of Hznke) at least a varietal name. 
4. Z.vILLOSA. Very erect, 3—5 feet high, with straight as- 
cending branches: very villous with white, spreading hairs: 
leaves linear-lanceolate, apparently somewhat falcate, entire 
or rarely denticulate, thick, with a prominent midvein, mostly 
opposite, their axils having short, very leafy branchlets (as in 
the other species of this group): petals exceeding the seg- 
ments of the calyx but not half as long as the tube, which is 
cylindrical next the bulb-like base, thence widening into a 
long but not broad throat: stamens well exserted: capsules 
glabrous, pedicellate.
