Cymopterus terebinthinus T. & G. 
Common in the neighborhood of timberline, usually in stony places 
on dry pumice slopes; found also on top of Red Cone, a little east of 
Wagon Camp. This species has a large and woody root and a remark- 
ably rank and lasting odor. Its zone position is Hudsonian; a larger 
unrecognized form occurs in the Canadian zone. (Identified by Miss 
Eastwood and Dr. Rose.) 
Ligusticum grayi Coulter & Rose. 
Common throughout the Hudsonian zone, particularly a little below 
timberline, where it occurs most abundantly in the beds of heather 
along the little streams. In places it pushes down into the Canadian 
zone. (Identified by Miss Eastwood and Dr. Rose.) 
Heracleum lanatum Michx. Cow Parsnip. 
Occurs in damp places in the Canadian zone. In Mud Creek Canyon 
near the mouth of Clear Creek it was found as high as 6,700 feet. 
(Identified by Dr. Rose.) 
Osmorrhiza nuda Torr. 
Found sparingly at Wagon Camp and at Sisson. 
Cornus nuttalli Audubon. Oregon Dogwood. 
Rather common in moist places in the lower half of the Transition 
zone. It occurs in Squaw Creek Valley near McCloud Mill, and is 
common along the streams near Sisson ‘Tavern; on the road from 
Wagon Camp to Sisson it was seen up to an altitude of 4,500 feet. 
Cornus pubescens Nutt. 
Common in cool damp soil near Sisson and along the upper Sacra-

Fairly common throughout the Shasta fir forest, and also in the 
mixed forest of pines and firs from the upper Sacramento Canyon 
northward (Canadian and Transition). 
Pyrola picta Smith. 
Occurs here and there throughout the forest of Shasta firs, where 
its ornamental light-marbled leaves are pleasingly conspicuous against 
the dark soil.
