"ALLIUM DICHLAMYDEUM. Vegetative characters of the pre- 
ceding, but the plant only half as large: perianth deep rose- 
purple, 5 lines long ; outer segments oblong, abruptly acute, 
spreading, the inner lanceolate-oblong, erect and thus apart 
from the outer, their tips slightly spreading, all entire: 
filaments subulate, one third shorter than the perianth : ovary 
crested. 
Common on hills along the coast of California; abundant 
on seaward slopes of the Mission Hills, and at the Marine 
Hospital, San Francisco, flowering in May and June. The 
species is apparently confounded in the Botany of California 
with A. serratum, which belongs to the Mt. Diablo range 
(where the present plant does not occur), and the regions 
eastward, flowers in March and April, has smaller and rose- 
colored flowers, with minutely serrate segments. The peculiar 
attitude of the inner segments in A. dichlamydeum, forming, 
as they do, something like a pitcher-shaped cup in the midst 
of the others, would not be detected in the dried specimens ; 
hence the confusion. 
'ALLIUM crispuM. Bulb unknown: leaves several, linear, 
shorter than the scapes: scape 5—8 inches high, stout, 
gradually thickened above: spathe l-valved, cleft to the 
middle into 2 ovate, abruptly acute lobes, these eventually torn 
apart to the base by the expanding umbel : pedicels 12—25, 
stoutish, an inch long: perianth light-purple, 3—4 lines long, 
the outer segments oblong-ovate, plane, entire, the inner lan- 
ceolate, canaliculate, their margins minutely but strongly 
undulate: stamens broadly subulate, rather more than half 
as long as the perianth : ovary not crested. 
A beautiful species, allied to A serratum : obtained by Dr. 
Parry near El Paso de Robles, in San Luis Obispo County, 
California, April, 1888.
