that, but it is also thinner, and sori smaller often oblong and less prominent, 
more hairy on both surfaces, and stellate hairs with a larger number of rays; 
the copious scales too are different. When I first detected this plant in the 
woods on the East Coast in 1846, I noticed only a few specimens, and I 
thought it was only a “sport ” of P. rupestre; but where I lately found it, 
it was very plentiful,

Genus 41. Bartramia, Hedwig. 
1. Bartramia readeriana, sp. nov. 
Stems densely tufted, tall, robust, ascending, 4-inch diameter, 13-83 
inches long, vaguely dichotomously branched, thickly tomentose with red 
branched and implexed tomentum ; branches above fascicled, strict, almost 
glabrous, red. Leaves spreading (some are truly divaricating, at first spread- 
ing then bent downwards), pale yellow-green, shining, with a short sheathing 
base, ovate-lanceolate, acuminate, gradually narrowed into a very long hair- 
like point, serrulate to tips, plaited, minutely papillose, twisted (to the right) 
when dry contorted; nerve slender, percurrent; cells dense, linear, the 
marginal at the base larger oblong and translucent; perichetial leaves 
broader with lax cells. Fruitstalk 1-14 inches high, erect, red, shining. 
Capsule large, inclined or horizontal, ovoid, grooved when dry; operculum 
convex, apiculate; teeth red ; spores very minute. Calyptra 2 lines long, 
narrow, blackish at tip, apiculate. Inflorescence diccious; antheridia 
capitulate.

Obs. I. A species allied to B. pendula, sieberi and comosa ; differing 
from pendula, mainly in the very long points of the leaves, that are twisted 
when dry and papillose, and in the erect capsule; from sieberi, in the 
shining long-pointed and twisted leaves; and from comosa in the long- 
pointed, twisted and broader leaves, which are serrulate throughout, its 
densely tomentose stems, and apiculate operculum; and from all three 
species, also, in the translucent marginal cells at the base of leaves. It 
appears, however, to be nearest to this last species—comosa. 
Obs. II. This species seems to be scarce ; hitherto I have only detected 
it in two similar open ridgy spots, growing two-thirds concealed among 
dense and erect pale Hepatice (Mastigobryum, sp. nov. 2); and then only in 
small quantities, and rarely found in fruit, although I have visited those 
places some twenty times in hopes of finding good fruiting specimens. . 
From its dense and shaggy tomentum, and intermixed habit among the 
Hepatice, and aged appearance, it seems to be of very slow growth,
