﻿196 PLANTS KANEAN^E GR(ENLANDIC^. 



P. lanata, Willd. A larger plant than the two preceding, with erect, leafy and lanu- 

 ginous stems. Leaves linear-lanceolate, pinnatifid with the rachis remarkably dilated ; 

 the lower pinnules very small, the other larger and dentate. Spike leafy and crowded; 

 calyx half the length of the corolla, which is much smaller than in the two preceding 

 species, and of a j^ellow color. An old stem in fruit, seven inches high and quite 

 glabrous, with mucronate pods at least half an inch long, has the leaves bipinnate. 

 Other imperfect specimens from N. Proven are not half the size of those from Smith's 

 Sound, with very small flowers, seem to belong to the same species — perhaps a varity ? 

 Proven, 72° ; Fog Inlet, 78° ; Rensselaer Harbor, 79°. 



LABIATE. 



68. Thymus serpyllum, var, arcticum. Nov. var. Foliis pellucido-punctatis, ad 

 basin ciliatis, 5-venosis, venis subtusvaldeprominentibus. Calycis dentibus corolla?que 

 lobis ciliatis. 



This variety is probably the same as that collected by Vahl on the eastern coast of 

 Greenland, and described by Prof. Hornemann as var. decumbens. The stems are 

 quite prostrate, as almost all the forms of serpyllum ; the leaves are of a pale green 

 color, with pellucid dots, ciliate at base, and with veins remarkably prominent and 

 symmetrical. Flowers capitate among the upper leaves, which, as well as the calyces, 

 are tinged with bright purple. Calycinal teeth and lobes of the corolla ciliate. 



Fiske Fiord, 65°. 



DIAPENSIACE^E. 



69. Diapensia Lapponica, Linn. Asa Gray. Man. ed. 1, p. 346. I do not think 

 this plant was ever found before in such high latitudes. 



Collected by Dr. Kane on his return home in latitude 73°. 



POLYG ONAGER. 



70. Polygonum viviparum, Linn. Pursh's Fl., 271. Engl. Bot. T. 669. Rich, 

 app., p. 43. Asa Gray. Man. ed. 1, p. 386. 



Found at every station of both voyages. 



71. Oxyria digyna, Campd. A. Gray. Man. ed. 1, p. 391. 0. reniformis, Hook. 

 Rumex digynus, Pursh's FL, p. 248. Engl. Bot. T. 910. 



With the preceding at almost all the stations from 64° to 80°. 



EMPETRACE^E. 



72. Empetrum nigrum, Linn. Pursh's Fl., p. 93. Engl. Bot. T. 315. A. Gray.
