NEW OR NOTEWORTHY SPECIES. 915 
TRIFOLIUM MINUTIFLORUM. Annual, very slender, gla- 
brous, the numerous branches decumbent, a few inches to 
almost a foot long: leaflets 1 to ? inch long, the lowest ex- 
actly linear, truncate or emarginate, the others oblong-linear . 
and abruptly acutish, all somewhat serrately and very evenly 
denticulate: peduncles filiform, much longer than the leaves: 
heads not much more than 2 or 3 lines broad in flower; in- 
volucre parted into 6 or 7 oblong entire lobes: calyx-teeth 
subulate-lanceolate, herbaceous almost throughout : corollas 
moderately inflated in age. 
An interesting species, allied to T. truncatum and T. hydro- 
philum, which latter it agrees with in having the leaflets of 
its earliest leaves narrower than tliose of the later ones, in 
which respect these two differ from all other West American 
clovers. This one is of southern California and Guadalupe 
Island. Mr. Orcutt distributed it as “ T. gracilentum." 
TRIFOLIUM POLYODON. Annual, glabrous, the rather firm 
and not flaccid branches nearly prostrate, 1 to 2 feet long: 
lowest leaves on long petioles, those of the uppermost very 
short: leaflets of all obovate, of the lowest broadly so, of the 
Upper narrower, and these j to L inch long, all finely and 
sharply denticulate: peduncles short and firm, seldom sur- 
. Passing the leaves: heads many-flowered, about finch broad ; 
involuere of few broad setaceously multifid lobes: corollas 
small for the plant, dull purple: short calyx-tube with about 
10 distinct straight nerves and as many finer ones which 
branch above and form a few meshes; the teeth elongated 
and mostly setaceously 3-cleft. 
Plentiful in moist uplands along streamlets and springy 
Places at Pacific Grove near Monterey, Calif. ; collected by 
the author 27 May, 1895. A large and very distinct one of 
the annual species of the involucrate group, bearing much 
likeness to the equally rare or local T. appendiculatum. I 
am apprehensive it may prove identical with the plant of 
Prrronta, Vol. HI. Pages 215-230. Oct. 9, 1897.
