DRUMMOND'S NORTH AMERICAN MOSSES. 669 
222. Hypnum polyanthum, belongs to Bridel’s genus Py- 
laiseea, and is a new species, which we call Pyl. heteromalla. 
224. Hypnum erectum nov. sp., differs in no respect from 
Leskea rupincola Hedw. 
232. Fontinalis antipyretica. The sterile specimen be- 
longs to F. squamosa. 
236. Funaria Muhlenbergii, is F. Hibernica. 
247. Bryum trichodes var. is Meesia Albertinii Bryol. 
Europ. 
253. Bryum punctatum. This plant resembles certainly 
small-leaved forms of Mnium punctatum; it differs, how- 
ever, essentially from that species in its more delicate leaves, 
Which are not terminated by a short mucro, and which are 
bordered with a loose cellular margin; the male flowers are 
also different. We, therefore, must regard this elegant moss 
as a distinct species, which may be called Mnium jingo: 
punctatum, 
257. Bryum spinosum. Very different from Mnium spi- 
nosum. The leaves are more delicate, with a less pro- 
nounced margin, which is pale yellow. The marginal teeth 
of the leaves are longer, sharper, not in pairs nor spinular, 
but soft; and the pendulous capsule is smaller. It differs 
also in the male flowers. We have named this species 
after its discoverer, Mnium Drummondi. 
259. Bryum marginatum, is Mnium orthorhynchum, var. 
tenellum, capsulis oblongis attenuatis. 
260. Bryum carneum, is Br. Wahlenbergii, as is also No. 261. 
263. Bryum nutans var. The specimen marked A is Bry. 
(Pohlia) acuminatum var. pulchellum : and B is Bry. (Clado- 
dium) arcticum ; the same form as occurs in Switzerland, the 
Tyrol, and Norwey. 
266. Bryum turbinatum, is Br. (Clad.) inclinatum, var. foliis 
angustioribus longius aristatis. 
267. Bryum turbinatum var. pallens, is Br. (Clad.) pene 
sum. 
276. Polytrichum commune var. formosum, is the common 
form of P. commune. E
