Var. /3, foliis subdisticliis. H. Arbuscula, Sclnvaecj. Snppl. t. 300.
Hab. Lord Auckland's group and Campbell's Island ; rocky places on the hills; and on the ground in the woods, where it was found in fruit by Dr. Lyall. Var. /3, Lord Auckland's Island ; barren. (Br. Lyall.)
The original specimens, figured in the ' Musci Exotici,' are there correctly described as baring the leaves imbricated all round the stem, but the seta is represented too long and slender. The stems of the var. /3 are somewhat compressed, and the leaves thus become in a measure distichous, as shown in Schwaegrichen's figure, winch may indicate, a different species. The majority of our specimens agree well with the figure in ' Muse. Exot. ;' except that the theca is more truly elliptical and somewhat apophysate, gradually tapering downwards into a thick slightly curved seta, which is very Little longer than the capsule and barely exserted beyond the perichartial leaves. We have never seen the seta so short, or the theea so globose, as they are represented by Schwaegrichen. The arcuate stems sometimes root at the apex.

Hab. Lord Auckland's group and Campbell's Island; on the ground in the woods, rare in fruit.
The calyptra is remarkably long in this moss, lanceolato-subulate, slightly inflated when young, of a rich chestnut-brown colour.

Hab. Lord Auckland's group ; forming large tufts in the woods near the sea, rarely fruiting.
In habit this fine moss resembles some species of Bartramia.

Caules 2-4 unciales, vage ramosi, ramis rigidis simpliciusculis, curvatis. Folia dense imbricata, rigida, basi ovata, deinde setaceo-subulata, nervo valido excurrente longe acuminata, subconcava, basi obscure plieata, atroviridia, siccitate suberecta, areolis minutis ; perichatialia minora, ovata, nervo longe exserto.

This is a very common moss in the northern island of New Zealand, growing on rocks, on the exposed roots of large forest-trees, especially of the Podocarpus dacrydioides, and upon stones in streams of water; under the last circum-
