leucop/iyl/aAxe not listed hv Wntson, unless the latter is included 

 under his P. circinata. In addition to these there are several 

 species as yet nndetL-rniined, aniono^ them an apparently unde- 

 scribed Arnica. 



On Auo;ust 6th Lainf)illc canyon was explored, our inten- 

 tion being to penetrate as far as the head of the canyon. lint 

 havinor taken the wrong side of the stream, traveling was very 

 diflRcult on account of the overgrown condition of the trail, 

 which was sometinics lost altogether, .so at 7400 feet, where the 

 canyon forks, we (lecidcHl to hall. The rid^e hing between the 

 forks was ascended to 8200 feet, when the waning afternoon and 

 the close thickets of aspen put an end to further advance. A 

 number of species were collected, the types of which were orig- 

 inally found on the Ruby range. 



A single plant of Delphinium diversifolium Greene, was 

 found in a gra.<;sy thicket at 7050 feet, but two days later it was 

 encountered in fair qumtity well up on the ridge north of the 

 canyon at 9750 feet. Dr. Greene probably got his type on the 

 Clover mountains. 



Delpliiuiiini occideiitale Wats., was plentiful in rich .soil in 

 and near an aspen forest at 8000 feet, the plants rank and luxu- 

 riant. Watson first got it near the southern end of the range, 

 but reports it also from the Clover mountains. 



Gorinania debilis (Wats.) Britton, occurred at 6800 feet on 

 a moist north slope, in thickets, carpeting the ground in places. 



P^/^/.y/^wc'// /r^/<?;/jz'i- Greene, was found in a small grassy 

 meadow at 7050 feet, quite an extension of its altitudinal range. 

 But it was not so plentiful as in the meadows at the foot of the 

 range, where it occurs at from 5300 to 5800 feet. 



Sphaej'omrria cana (D. C. Eaton) Heller, was found spar- 

 ingly about the clifTs at the fork of the canyon at 7400 feet. 

 The tvpe was collected near the southern end of the range on 

 limestone. Here also was found the curious little Petrophyti{7)i 

 caespitosum (Nutt.) Rydb., clinging to the rocks. Later it was 

 noted on limestone rocks near Cave Creek. 



Antennaria anaphaloides Rydb., was obtained at 8200 feet 

 in rather dry ground on a northerly slope. This is evidently 

 the A. carpathica var. pukherrima listed by Watson.
