Cerasus emarginata Dougl. Bush Cherry; Bitter Red Cherry. 
Abundant in places in the chaparral of the Transition zone. In 
Sacramento Canyon, south of Shasta, it begins at ‘The Loop,’! and 
ranges up to the lower edge of the Canadian zone. It is profusely 
abundant at Wagon Camp, where it is a straggling bush « little higher 
than a man’s head, and usually grows in thickets. It ascends Mud 
Creek Canyon to an altitude of 5,600 or 5,700 feet. 
Cerasus glandulosa Kellogg. 
A sapling or small tree having large broad leaves; collected by me 
a short distance south of Sisson Tavern. (Identified by Professor 
Greene.) 
Prunus subcordata Benth. Wild Plum. 
Common in places along the southern and western borders of Shasta 
Valley, usually in the edge of the open Pinus ponderosa forest and 
often growing with Rhus and Kunzia. We found it also near Etna, 
on the west side of Scott Valley. 
Cercis occidentalis Torr. Red-bud. 
Reported from Mount Shasta in the Botany of California, but not 
found by us except in the Sacramento Canyon, where it is common. 
Lotus americanus (Nutt.) Bisch. [= Hosackia americana. | 
Common in the Transition zone at Wagon Camp, and thence along 
the road to Sisson, growing chiefly in open places in the chaparral. 
Lupinus elmeri Greene [= L. albicaulis sylvestris Auct. | 
Common in places throughout the upper part of the Transition zone, 
and ranging into the Canadian. Common at Wagon Camp and a little 
above. Found also in Mud Creek Canyon at mouth of Clear Creek. 
(Identified by J. B. Leiberg.) 
Lupinus ‘ornatus’ Auct. [uot of Douglas.| Silvery Lupine. 
This beautiful species is common in spots near and a little below 
timberline, sometimes covering extensive areas, but not uniformly dis- 
tributed. Where it occurs it is usually sufficiently abundant to give 
the mountain side the effect of a distinct silvery covering. It always 
grows on stony or pumice slopes and usually among or near white bark 
pines, although in a few instances it was found outside of the pine 
areas. It is common near the head of Squaw Creek and on both sides 
of Mud Creek Canyon. On the east side of this canyon it is particu- 
larly abundant just above the trees, aid stops abruptly at an altitude 
of 8,200 to 8,400 feet, to be replaced by the dwarf Alpine LZ. lyalli. On 
the north side of Shasta it is common in an open forest of white-bark 
1TIn this and subsequent references to ‘The Loop’ the statement means that in 
going north along the railroad track we first saw the plant at ‘The Loop.’ The 
species may occur farther south in the canyon on suitable slopes above the level of 
the railroad.
