its rose-colored flowers, its cdontate helmet, and the thin texture of its 
corolla and calyx. The middle lobe of the inferior lip and stigma are 
not emarginate as in P. arctica , and the germ is of a more globose 
form. It is, moreover, a larger plant, with many more stems and a 
more flesby root. Smith’s Sound Stations.

Am. 2, p. 100. P. lanata , "VYilld. A larger plant than the two pre¬ 
ceding, with erect, leafy and lanuginous 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 pre¬ 
ceding species, and of a yellow color. An old stem in fruit, seven inches 
high and quite glabrous, with mucronate pods at least half an inch long, 
has the leaves bipinnatc. Other imperfect specimens from N. Proven, 
not half the size of those from Smith's Sound, and with very small flowers, 
seem to belong to the same species, and are perhaps a variety minor .

LABIATES. 
68. Thymus serpyllum, var. arcticum. Nov. var. Foliis pellucido- 
punctatis, ad basin ciliatis, 5-venosis, venis subtus valde prominentibus. 
Oalycis dentibus corollmquc lobis ciliatis. 
This variety is probably the same as that collected by Yahl on the 
eastern coast of Greenland, and described by Professor Ilornemann as 
var. decumbcns. The stems are quite prostrate, as almost all the forms 
of serpt/Ilum; 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.
