158 This and the following may be considered representatives of the British /. reptans, L., to which the present is very nearly allied, though differing in the much smaller size, the less pinnated stems, the more distant leaves which have not the singularly prominent cells of the northern plant, and especially in the short perichaetium and elongated calyx. It is also a native of New Zealand, in the Flora of which country it will be figured.

This plant approaches nearer to the /. reptans, L., than the former ; it is, however, very much smaller, the leaves more closely imbricated, generally more deeply divided and narrower at the base.

Hab. Lord Auckland's group ; on the dry trunks of trees and on the ground.

A curious little species, first described by Dr. Greville, who gives an excellent figure of it, from New Holland specimens.

47. Jungekmannia tetradactyla, Hook. fil. et Tayl.; csespitosa, implexa, caule debili prostrato subpinnatim raruoso, foliis subremotis distichis patentibus basi quadratis quadrispinosis spinis articulatis, stipulis minimis quadripartitis, calyce elongate cylindraceo ore contracto eiliato.

Hab. Lord Auckland's group ; creeping over patches of /. coalita. Caspites 1-2 unc. lati, pallide flavo-virides. Caules interdum 1 unc. longi, innovationibus plurimis ramosi; celluke externse latre, pellucida?, alba?, centrales virides, opacse, hinc cauhs sub lente quasi ala membranacea cinctus appareat. Folia caulina reniota, ramidina (plerumque superiora) conferta, basi angusta, deinde latiora, hi spinas elongatas desinentia. Stipula caide vix latiores, segmentis subulatis.

Closely allied to the /. centipes, nobis, of Tasmania, from which it may be distinguished by the (transparent) more branched and pinnate stems, the more distant and patent transparent leaves, which are more deeply divided, with the segments elongated and setaceous: the two species are very near in other respects.

From New Zealand we have this plant with calyces and perigonia ; the former are remarkably large in proportion to the size of the plant, being as long as the shoots winch bear them, they are ovato-cylindrical and slightly bent on one side. The perichastial leaves are erect, with a longer entire portion or base than the cauline. Perigonia forming cylindrical spikes, their leaves large, bifid above with tumid bases, each containing in its axhla a single mi- nute, round, brown, pedicellated anther.
