Var. f t Camphell’s Island.
Caules 1-2 imcitiles et ultra, densi, fragiles. Jolia seiuiuncialia, nitido, flaiida, solidinervia, nervo in aristam

We are not acquainted with any species with which the present could be confounded. F. hugisetmn, Hook.,
has tbe leaves of a simüar form, but their nerve is very broad and indistinct, and the theca is erect. F . capillaceum,
Brid. (Bryol. Univ., vol. u. p. 460), difl'ers in the striated capsule. The stems of the var. 3 are four inches long,

H ab. Lord Auckland’s group aud Campbell’s Island ; growing both in moist and dry places on the liiUs.
This species is remarkable for the divergence ot the filiform apices of its leaves and the broad nerve which is
obscurely lamellated at the back, tbeir margins also are so inflexed as to give them a subulate appearance. Tbe numerous
thecæ arise from aggregated perichætia and are quite hm-ied and concealed amongst the fohage. New
Holland specimens of this moss exist in the Hookerian Herbarimn under the name of F. pudieum, Hornsch. F.
capitipTum, Pal. de Beauv., from Bomhon, has more strict leaves, more distinctly lameUated at the hack.
2. Campyloptis fiextiosus, Brid. ; caule erecto snbramoso, foliis rigidiuscnlis concavis subulatis acuminatis
nervo lato continuo, seta curvata, theca ovata striata, operciflo recto cuspidato. C. flcxuosus, Brid .

Peristomium simplex; dentibus sedecim, pjramidatis, per paria approximatis. Calyptra cucnUiformis.
This genus corresponds with the Cynadon of Bridel, a preoccupied name. Tlie present species does not accord
with Schwaegrichen’s definition of Cynodontium, and wc are thus obliged to estabhsb a genus for its reception.

I Iab. Lord Auckland’s group and CampbeU’s Is lan d ; on moist rocks at an altitude of 1200 feet in
the former locality, descending lower in the latter. Var. f t Lord Auckland’s group, with th e former.
Cmles sesquiunciales, cæspitosi, fastigiatim ramosi, ramis gi-acUibns. Folia erecta, siibsecunda, striata, siccitate
appressa, subrigida, longe lineari-setacea, basi lanceolata, vaginantia, flavo-viridia, inferiora nigi-esccntia ; nervo

The singular apex of the leaf distinguishes this species, even in a barren state, from Weissia contecta, or any
similar raoss.

Wc would gladly avaü ourselves of Briicb and Scbimpcr’s subdivisions of tbis genus, as proposed in tbe ‘ Bryologia
Eiu*opma,’ did not the antarctic species prove them to be unnatural. Even the European species do not coincide
with the views of those authors, for the Pogoiiatum naiium, Br, and S., has the inner membrane of the sporangium
surroimding the columella perfectly cyliiiihical, and thus is at vaiiance with then dcfmitiou ; and there is nothing
essentially dilfcrent between its structine and tbat of Atrklium, of the corresponding membrane in whicli no mention
is made. This inner sporidifcroiis hning of the columella exists in all mosses, as well as iu the Atrklmm undidatum,
Br. aud S., aiid is the portion of the seminal sac, which, being inverted at the base, ascends the axis of the theca
surrounding the columella ; it forms the visible columella ; the tissue itself, being often of extreme tenuity, is frequently
overlooked and its continnity with the sporular membrane is not always evident. We have attempted to
explain this structure at p. 120, under Sphagnum.. That the characters derived from the calyptra are not of generic
value is proved hy that organ being exposed in P. nmgellanieicm and dendroides, which have otherwise all the characters
of Fogonatum. The origin of the vüloiis hairs composing the outer calyptra of many species and their
original attachment to the vaginula did not escape the notice of Ehrhart and Molu- and subsequently of Wableiiberg,
althoiigb overlooked by Bruch and Schimper, whose analyses of the genera of mosses are imequalled in point of cxc
