NEW PLANTS FROM MIDDLE CALIFORNIA. 75 
banner which greatly surpasses the other petals, these all at 
first dingy-yellow but at length copper-color. 
Hackett’s Meadows, at 8600 feet, July 18, Baker’s n. 4373. The 
plant by habit is next of kin to Z. formosissimus (Hosackia 
gracilis Benth.) of the Californian seaboard, but the flowers are 
- extremely different. 
SIDALCEA RANUNCULACEA. Stems 1 to 2 feet high, mostly 
solitary, terminating a slender superficially seated horizontal 
rootstock, retrorsely hirsute from the decumbent base to near 
the middle; herbage of a very light green, the long petioles and 
upper part of stem sparsely hirsute-hairy: leaves orbicular, the 
lowest 7%-cleft and the segments with 2 or 3 obtuse lobes, the 
cauline more deeply cleft and their segments acutely 3 to 5-lobed, 
those near the spike 5-parted, the segments lance-linear, entire: 
spikes very short and dense, and flowers rather large: calyx and 
pedicels densely villous-hirsute: fruit unknown. 
In Hacket’s Meadow at 8,600 feet, Culbertson; n. 4318 of 
C. F. Baker’s distribution. The same, but in poor specimens, 
was collected by Dr. Edward Palmer, in the same region, in 
1888 (n. 203) and distributed for S. sfzcata, from which the 
species differs essentially by its broad oval spikes, large flowers, 
and a peculiar foliage recalling that of some Ranunculi. 
> SIDALCEA INTERRUPTA. Size of the last much more slender, 
apparently also rhizomatous, the stem and petioles loosely pilose 
with firm spreading hairs; herbage deep-green, but cut of the 
leaves much as in the last; flowers much smaller, in elongated 
and often interrupted: spikes, or even with solitary flowers scat- 
tered up and down below the terminal spicate cluster: pedicels 
and calyx-tube stellate-pubescent only, but teeth of the latter 
pilose: fruit much depressed, the nutlets nearly or quite glab- 
rous, obviously though not strongly reticulate. 
Habitat of the last, nearly but at a lower altitude, 8,000 feet, 
and by the same collector, being numbered 4255 by Mr. Baker. 
SILENE APERTA. Perennial, slender; erect, 2 feet high or 
less, with but a single pair of cauline leaves near the middle, 
these narrowly linear and about 3 inches long, the innermost
