MONTANA BOTANY NOTES, 



Additions. 



During the season of 1910, in company with Prof. M. J. Elrod 

 Director of the Biological Station and Prof. Kirk wood, I made a 

 tour of the Glacier Natl. Park. We reached Soniers on the beau- 

 tiful Flathead Lake on July 31st. A day was spent there and an 

 Opuntia was collected which Dr. Rose has described as new (but 

 which I regard as only a small form of 0. mesacantha) and some 

 other plants new to the region. We all reached McDonald Lake 

 Aug. 1st. The object of this trip was to complete the examination 

 begun in 1909. In that year we visited the lase, Sperry Glacier, 

 the Continental Divide, and Gunsight Pass and Lake and Black- 

 foot Glacier, on the Hudson Bay slope. In 1910 we spent four 

 days at Avalanche Lake, about a week at Mineral Park and Swift 

 Current Pass (Continental Divide), thence over on the Hudson 

 Bay slope to Waterton Lake just on the British line, thence over 

 Brown Pass to Bowman Lake and Adair, thence southward to Mc- 

 Donald Lake. The trip took a month. The botanical work was 

 thorough till we dropped down toward Waterton Lake; from there 

 the trip was too hurried. Good moss collections were made at Mc- 

 Donald Lake, Mineral Park and Greenwood's Camp near Waterton 

 Lake only. Little was done with lichens or fungi except to get 

 anything noticeably different. Hydna were collected, several spe- 

 cies but not identified. Messers Holzinger, Fink and Peck named 

 species as before.
