HARRIMANELLA, A NEW GENUS OF HEATHERS. 575 



Muir Glacier, we found it again, growing at an elevation of about 

 2,000 feet in the rather open forests of black hemlock ( Tsuga iner- 

 tensiatia). At this time, June 12th, it was not quite in flower. The 

 first flowering specimens were found June i6th on Mount Verstovia, 

 near Sitka. The plant occurred in abundance from an elevation of 

 3,400 feet to the summit, and one patch was seen on an exposed ridge 

 at about 1,500 feet. Near sea level on the west shore of Yakutat 

 Bay on the glacial gravels half covered with vegetation was seen a 

 single yellowed plant with pale whitened flowers, doubtless the prod- 

 uct of a stray seed from the mountains above. At various points in 

 Prince William Sound the plant grew in great profusion and was in 

 full bloom at the time of our visit, June 24th to 29th, occurring on the 

 mountain slope back of Orca among the dwarfed black hemlocks at 

 1,300 to 1,600 feet, in Port Wells, and in Columbia Fiord. This is 

 the plant that lead Mr. Gilbert to adopt the name Heather Island for 

 the rocky, mossy, scantily timbered island that stands in Columbia 

 Fiord immediately in front of the Columbia Glacier. On this spot, 

 chilled by the cold current of air flowing down from the great glacier, 

 grew this and other arctic-alpine plants in profusion all the way down 

 to sea level. On a timbered nunatak rising from the glacier about 

 eight miles from its front the plant occurred to an elevation of about 

 3,000 feet. On the mountains at the head of English Bay, Kadiak 

 Island, it was flowering abundantly at 1,500 to 3,000 feet. It was 

 found on the Alaska Peninsula at Kukak Bay by Mr. Kearney and at 

 Chichagof Bay by Mr. Palache, at an elevation of about i ,000 feet, 

 and sparingly on the Shumagin Islands by Mr. Kincaid and Mr. 

 Saunders at the same altitude, flowering till the middle of July.

 mountains of Lapland, but the species is now known to occur in arctic
