66 PITTONIA. 
County, California; collected by the writer, April 15, 1887. 
A species in some respects intermediate between L. micran- 
thus and L. bicolor, which two have unfortunately been con- 
founded by recent authorities, but which are as well distin- 
guished and as far from intergrading as any other two of our 
annual lupines which are not of different natural groups. L. 
pachylobus possesses something of the habit of L. bicolor and 
the small flowers of L. micranthus, but it has its own peculiar 
pubescence while its pods are remarkably unlike those of 
either of the two to which it stands nearest. In the fresh 
plant these are very thick and succulent, almost terete, weigh- 
ing the branches, which are by no means weak, quite down to 
the ground. 
TRIFOLIUM FrILIPES. Erect, slender, a foot or more high, 
the root annual and herbage glabrous: leaflets linear, acute, 
spinulose-serrulate, an inch long, on petioles of a half inch, or 
those of the lowest much longer ; stipules with subulate 
teeth : peduncles filiform, 2—3 inches long and far exceeding 
the leaves: head with a small, deeply laciniate-cleft involucre, 
1—12-flowered : flower 2—3 lines long, purple and white, the 
wings meeting in front of the emarginate keel: calyx-teeth 
shorter than the tube, ovate-aeuminate, spinose-tipped, entire, 
equal, the entire calyx in fruit compressed, the opposite pairs 
of teeth mutually appressed above the included obovate 2- 
seeded pod. 
Apparently confined to wooded hills back of Berkeley and 
Oakland, California, growing with such plants as Micromeria 
Douglasii, Trientalis Europea, ete.: collected by the writer 
at Berkeley, and at Oakland by Mr. V. K. Chesnut. A very 
good species, related to T. tridentatum, which latter has some 
characters yet to be brought out. 
CARPENTERIA CALIFORNICA, Torr. Pl. Frem. 19. t. 7.— Some 
forty years have elapsed since General Fremont brought, from 
some uncertain locality in our Californian mountains, the
