the slender petiole of 5 mm, irregularly serrate, the teeth sharper and 
closer. than on the leaves of the young shoots, the end commonly broad, 
but occasionally pointed; fruit purple-black, small, about 4 mm in dia- 
meter, surmounted by the five short obtuse calyx lobes; in size and general 
appearance much resembling the common black huckleberry of the East, 
whence the specific name. 
No. 6052, in fruit only, collected in thickets in low ground along the 
lagoon at Sebastopol, Sonoma county, August 20, 1902. Heretofore 
this distinct species has passed for C. rivularies Nutt., collected originally - 
by Nuttall in the Rocky Mountains of Montana.

Annual: 4—6 dm high, pale and somewhat shining, especially below; 
pubescent with short hairs; branched from the base, the branches as- 
cending, rather weak; lower leaves oblong, with a maximum length of 
about 8 cm, 1 cm wide, shallowly sinuate, narrowed below to a clasping 
base, usually blunt, the upper successively shorter and somewhat broader, 
becoming sessile, the ones contiguous to the inflorescence ovate and half 
as broad as long, acute; calyx only 1 mm long, the lobes oblong, obtuse; 
corolla 4 mm long, canary-yellow, the lobes oblong; filaments not dilated; 
capsule narrowly linear-clavate, 2—5 em long; seeds in a single row, 
short-prismatic, the angles and one side grooved, apparently not tuber- 
culate. 
No. 5910, collected on the southerly slope of Mt. Sanhedrin, Lake 
county, July 19, 1902, en the ridge above the sawmill. It grew in 
abundance in dry, gravelly ground near pine trees. Although distributed 
as M. integrifolia (Wats.) Rydb., it is evidently distinct from that species, 
the original of which came from the Roeky mountains, or perhaps from 
Idaho, if “663 Geyer” is taken as the type, and is said by Watson in 
Bot. King Exped. 114, to have “flowers and fruit as in the ordinary 
M. albicaulis”, the petals of which are described as “scarcely exceeding 
the short subulate-lanceolate calyx-segments”.
