which are sufficiently perceptible though of only half the diameter of the bail's themselves, these are perfectly straight
and inserted near the base of the vaginula.

H a b. Lord Auckland’s g ro u p ; moist ground, amongst grass near the tops of the hiUs.
Theca jimior erecta, matm-a inclinata, tandem horizontalis, basi snbgibbosa, fusco-brunnea.
In the peculiar form of the capsule (ib represented iu Hedwig’s tigm*e) and in general habit, this moss bears a
strong similarity to Baxcsonia; Menzies, who describes the theca as subcyluidrical in the Limia?an Transactions
(vol. iv. p. 71.), is the only obseiwer who has reinaiked its peculiar structure. The naked calyptra allies this species
to the Catharinea of Bridel, whence some may include it under the dirision called Fogonatum by Bruch and Scliim-
p e r; on the other hand, the absence of an apophysis -will connect it with Oligotx'ichum. From Folgtrichxim of Bmcli.
and Schimper, it differs in wanting proper angles on the capsule, and from Atrichum, of the same authors, iu having
the inner or inverted portion of the sporular membrane stuTounding the columella 4-winged.
This moss is found in as low a south latitude as Brazil, from whence we have seen specimens collected by lladdi
aud named Catharinea pseiido-polyixichum, and there are others in the Herbai'ium formed by Mr. Gardner. It varies
in the length and somewhat in the disposition of the leaves, which are sometimes widely spreading and squarrose,
but in the specimens now imder consideration, they are shorter than iu others from Cape Horn. The seta is also
of variable length.

Conostomum has recently been united with Bartramia, by Bruch and Schimper. The genus is still an eminently
natural one. It is not upon the most evident characters, such as the various species of Polytrichum present,
however constant they may be, that natmal genera can in many cases be founded.

A more robust species than the B. pateus, with broader and more rigid leaves, their dilated bases truly quadrate.
Tlie capsule is perfectly erect and tbe operculum rostcUate. It esseutially differs from the former in the
dioecious inflorescence. The thecæ are not in a fit state to show the peristome, if this moss really possesses one. of
which we have some doubt. Tliis is not distinguishable from the B. potosica of Montague (ilim. Sc. Nat., 2nd
Series, vol, ix. p. 66), judging only from the description of that author ; but an examination of authentic specimens
proves the two truly distinct, the latter being more closely aUicd to B. patem, though having shorter leaves with their
bases not quadrate, but oblong or almost obovate.
