OCT., 1899] PLANTS. 151 



Cerasus emarginata Dougl. Bush Cherry ; l>itter Ked Cherry. 



Abmuhiiit in phices in the chaparral of the Transition zone. In 

 Sacramento Canyon, south of Shasta, it begins at 'Tlie Loop," and 

 ranges up to the lower edge of the Canadian zone. It is profusely 

 abundant at Wagon Cauip, where it is a straggling bush a little higher 

 than a man's head, and usually grows in thickets. It ascends Mud 

 Creek Canyon to an altitude of 5,()()0 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, usnally in the edge of the open Finns ponderosa forest and 

 often growing with Bhiis and Kunzia. We found it also near Etna, 

 on the west side of Scott Valley. 



Cercis occidentalis Torr. Red-bnd. 



lleported 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. [= HosacMa 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 (Treene [= L. alhicaulh sylvestris Auct.] 



Common in ])lacfS througliout the upper part of the Transition zone, 

 and ranging into the Caiuidian. 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. [not of Douglas.] Silvery Lupine. 



This beautiful species is common in spots near and a little below 

 tiniberliue, 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 Sipiaw 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, and stops abruptly at an altitude 

 of 8,200 to 8,400 feet, to be rei)laced by the dwarf Alpine L. lyalll. On 

 the north side of Shasta it is common in an open forest of white-bark 



'In this and subsequent references to 'The Loop' the statement means that in 

 going north along the lailroail ti"ack we first saw the jilant at 'The I-oop.' The 

 spt'cies may occur farther south in the canyon on suitable slopes above the level of 

 the railroad.
