ple tipped with white; heads ovate-conical in fruit, terminal or 
subterminal, main stem terminating in a peduncle 4 to 6cm. 
long, those of the branches much shorter: calyx tube 2mm. 
long, teeth 2mm. long, densely silvery pubescent: corolla ex- 
tending beyond the teeth about 2mm.; vexillum 6mm. long, 
2mm. wide, narrowly elliptical, obtuse, very finely erose dentate 
at apex: ovary 2-ovuled, hairy: style about 3 mm. long: legume 
membranaceous, striate, hairy towards the apex, 1-seeded: seeds 
light brown, not mottled, 2mm. long, less than 1 mm. wide. 
The type is a specimen from Surf, in the herbarium of P. 
B. Kennedy. A co-type is deposited in the U. S. National Her- 
barium. 
TRIFOLIUM ALBOPURPUREUM T. & G. (Plate 4.) 
An ascending or slightly decumbent simple or branched 
annual about a foot high, pubescent throughout, but not as 
densely so as most of the species of the group. The heads are 
very short peduncled when young, but the peduncles elongate 
considerably with age. The lower leaflets are smaller and 
broader than the upper, and inclined to be obovate-cuneate, 
emarginate, varying as they ascend to broadly, and finally nar- 
towly elliptical leaflets. The corolla in very young flowers is 
considerably shorter than the calyx. This varies with the age 
of the flower, and it may slightly exceed the calyx. The vexil- 
Inm, wings and keel are tipped with white. Both the calyx 
tube and the teeth are covered with dense white straight hairs. 
The teeth may be twice or more the length of the tube, accord- 
ing to thestage of growth. This species has been found in Cal- 
ifornia only, and it is very probable that Douglas collected the 
type in the vicinity of Pacific Grove or Monterey. Taking my 
plants from Pacific Grove, collected in May, 1907, as being near- 
est to the type and the drawings on the type sheet, as well as 
closely answering the original description, the following is drawn 
from them: 
Annual, 2 to 3dm. high, ascending, simple or branched, 
pubescent throughout: stems sparingly appressed pubescent for 
the group: upper internodes rocm. long: lower leaves on peti-
