The Flora of the Adirondacks. 81 



The summit of Whiteface though bare of trees is by no 

 means destitute of vegetation. A species of whortleberry 

 Vaccinium Ccespiiosum, not found elsewhere in the state 

 grows among the crevices in great abundance. Here we 

 find the rare Sireptopus Roseus with its clasping taper- 

 pointed leaves and pendulous, bell shaped, rose-purple 

 flowers, and the Luzula Parviflora. The Diapensia Lap- 

 ponica which, save on the White mountains, has no home 

 elsewhere than on these peaks this side of Labrador and 

 the northern regions of Europe; the Empetrum Nigrum, 

 black crowberry, a native of the coldest regions of British 

 America, is here ; the Nabalus Bootii with its haliber-shaped 

 leaves and the Nabalus Nanus are both peculiar to these 

 Alpine summits, the highest peaks of the White mountains 

 of Mount Marcy and Whiteface, being the only home of 

 either as far south as the United States. 



But these towering peaks are also crowned with beauty. 

 There can be none with senses so obtuse as not to be 

 delighted with the minute and delicate little Arevaria 

 Groenlandica whose little white stars fill up the crevices of 

 the rocks, fearless in its spotless innocence of the cold 

 storms that sweep about it all seasons, and the beautiful 

 white-flowered Potentilla Tridentata forms an elegant 

 carpet over many an unsightly rock. The Arbutus Alpine, 

 found only by myself in this state, creeps among the 

 wortle bushes, upon the very summit. 



We have passed hastily from the Champlain valley 

 through the hilly country, and to the mountain tops, 



Aulacomnion Turgidum, Mt. Marcy. 



Bryum Pollens, Whiteface. Found also by Mr. James, about the same 

 time on White Mountains. 



Conostomum Boreale, Marcy, Mclntyre. 



TetrapModon Mnioides, Whiteface, also on Catskills. 



Pylaiscea Polyantha, Adirondacks and Catskills not found elsewhere on 

 this continent except in British America. 



Hypnum Montanum, H. Dimorphum, and H. Sarmentosum, Adiron- 

 dacks and White Mountains.
