OCT , 1899.] PLANTS. 155 



Mentzelia laevicaulis (Dougl.) T. vv: G. 



liatlier common in Shasta Valley, but not found elsewhere about the 

 mountain. This species seems to belong to the Upper Sonoran zone, 

 and therefore has no place in the flora of Mount Shasta. 



Epilobium spicatum Lamarck. Willow Herb; Fire- weed. 



Abundant in places, chiefly on old burns in the Canadian and Tran- 

 sition zones. At Wagon Camp it did not begin to flower until near the 

 middle of August; at Sisson it was still in flower in places as late as 

 the middle of September. 



Epilobium brevistylum Bar bey. 



Collected at Wagon Camp, where it is tolerably common in moist 

 places; the largest species next to spicatum. (Identifled by Professor 

 Trelease.) 



Epilobium oregonense Hausskn. 



Common at Wagon Camp. A large form occurring also at Wagon 

 Camp Professor Trelease considers as probably E. (jlaherrtvium Barbey. 



? Epilobium hornemanni Eeichenb. 



Some poor specimens, with exceedingly long seed capsules, collected 

 by me a little below timberline about the end of the season, are doubt- 

 fully referred to this species by Professor Trelease. 



Epilobium clavatum Trelease. 



Abundant in the heather meadows and along the edges of the cool 

 streams of the Hudsonian zone at and a little below timberline. 

 (Identifled by Professor Trelease.) 



Epilobium pringleanum Hausskn. 



A tiny alpine species, rarely as tall as one's thumb, occurring here 

 and there on the borders of the highest streamlets above timberline. 

 (Identified by Professor Trelease.) 



Epilobium obcordatum Cray. Rose Epilobium. 



Local — common near timberline on the steep west side (east slo])e) of 

 Mud Creek Canyon. A remarkable plant, strikingly unlike the others 

 of its genus. It has a woody base and is really a dwarf bush. Its 

 large red flowers are showy and very handsome. (Identified by Miss 

 Eastwood and Professor Trelease.) 



Gayophytum ramosissimum T. & G. 



Abundant throughout the Transition zone, where it was equally com- 

 mon at Sisson and at Wagon Cam]) and was in flower as late as the end 

 of Sei)tember. (Identifled by Miss Eastwood.) 



Carum gairdneri (Hook. & Arn.) Gray. 



liather common in damp soil at Wagon Camp where the Canadian 

 and Transition zones meet. (Identifled by Dr. J. N. Rose.)
