Tbe leaves of tliis species meet back to back and are so closely imbricated that the stems appear triangular,
their anterior mai-gins not touching but learing a space whicli appears hke a gi-oove nmning down the whole length
of the stems, theii- recmwed mai'gins are rather tumid and decussate on the opposite face. In general habit tliis
resembles the J.punctata, Tayl., a species recently detected both in Ireland and the Canai-y Islands, from which the
gibbous or obhque leaves ivbl readby distinguish it.

This agrees irith authentic specimens of Lehmann’s plant, except in the summits of the stems not being so remarkably
cii-cinnate as they ai-e described. Such circinnate summits, however, are tndy perigonia, whose leaves are
smaber, more ventricose and erect than those of the stem ; and further, some of them contain in their axibæ a single,
rather large, pedicebated anther. Our specimens are about half an inch long, stout and curved ; the leaves much
more lax than in the former species.

H a b . Lord Auckland’s gro u p ; on alpine rocks, groiving amongst stunted tufts of Hymenophyllum
multifidum.
Cæspites diametro 1-2 unciales, inferne brunnei, superne flavi v. flavo-fusci. Caules erecti, 1 une. longi, subrigidi,
infeme nudi, parce ramosi, anni præcedentis sæpius innovati, apicibus subcurvatis. Folia disticha, subpatentia
v. divaricata, coriacea, apices versus 3-5 dentata, dente apicali majusculo acuminato, margine anteriore subrecurvo
deeurrente ; foba perichætii erecta, elongata, magis dentata.
This has much affinity to the J. decipiens. Hook., a very variable species in the form of the leaves, but in which
theh cebules are much larger and more lax, while in this they are so dense as to be hardly distinguishable. The
European plant differs further from the present in a character abuded to by the authors of the ‘ Synopsis Ilepati-
carum,’ who remark, “ J. decipiens ab omnibus congeneribus margine dorsali folii inflexo nec refiexo differt.”

H a b . Lord Auckland’s group ; on moist rocks, near the summits of the IbUs.
Cæspites subdensi, 2-3 unc. diametro, pallide straminei v. vii-escentes. Caules fu n e , longi, subrigidi, simpb-
ciusciili. Folia inferiora integra v. interdum unidentata, superiora apices versus plus minusve irregulariter crenato-
dentata, omnia conformia, basi angustata antice decurrentia, apices versus rotundata, cebulis distinctis. Calyx ter-
minahs, subpedicebatus, erectus, basi attenuates, fobis cauhnis vix duplo longior, ahs 4-5 angustis planis v. nigosis,
duobus oppositis interdum opacis, ore subtubuloso, crenato v. 4-fido, tandem fisso, fobis perichætii proprbs nulbs.
In external appearance tliis species very closely resembles the former, the leaves are, however, more loosely
cebular, and in the stmctui-e of the calyx it -widely differs. The Ferurian Fl. gymnocalycina, Lind., (Spec. Hep.
p. 48. 1.10) has the calyx equaby naked below and of a similar ontbnc, but it is smooth and furnished with only
two very obscui-e ribs, its fobage also is perfectly dissimbai- and the whole plant is much larger. The iv-ings of the
calyx are formed out of deep folds of its membrane.

In many respects this species resembles Montague’s F. pusilla (Voy. au Pole Sud, Bot. Crjqit. tab. 16. f. 3),
a species, judging from the plate, foimded upon a young and imperfect specimen, and which wæ think exists in
the Herbarium of the Expedition of a larger size. I t cbffers from this in the deep serratm-es of the leaves, iu the
habit and colom and above all, in belonging (according to the figure) to a section having the leaves coadunate at
the base. In the form of the foliage om: plant more nearly resembles the P. hemicardia, nobis, but is very cbfferent
in the disjiositioii of the leaves on the stem. A few calyces were observed ; they are I'ery uniform, shorter than the
perichætial leaves and concealed by them ; some are proliferous, the stem being produced through thcii- axis and exserted
: this abnormal state has been observed in J. Lyoni, Tayl., and in several species of mosses, as in Conomilrium
Berterii, Montagne (Crjptog. Boliv. t. 3. f. 4).
