1 3 4 FLORA ANTARCTICA. {AucMand and
Var. y, major; ioKis majoribus latioribus luride yiridibus, dentibus 8 geminatis. (T a b . LVII. Fig. TV. 6.)
H a b . lo rd Auckland’s group; Yars. a and ft in spongy bogs and in boles of trees in tbe woods,
frequent. CampbeU’s Island; var. a, not uncommon; aud var. f t in tbe wet and wooded valleys, on the
ground.
From its northern aby, S. mnioides, tliis species differs, both in the structure of the peristome and in the shorter
calyptra. which is mitrnsform and inflexcd at the base; also in the carinate leaves. The inflorescence appears truly
monoicous, once only we foimd a hci-maplu'odite flower. In the varieties a and f t the theca varies greatly in form,
and the colmnella is either included or exserted. In var. y, the leaves are often very large, aud the teeth connive
so closely as to appear hut 8, wliich are separable into 16 ; they are pale yeUoiv, each with a faint middle line : when
dry they are erect, recurved or reflexed, and generaUy of a pmple brown colour.

5. DRYPTODON, Brid.
Peristomium simplex. Denies sedecim, inæqualiter bifidi, v. apice lacero-fissi,
lacera. îVieca æqualis, auimlata. Brid. vol. i. p. 191.
This genus is perhaps not distinct from Gi'inmia.
1. D ry p to d o n crispzdus, Hook. fil. et Wils. ; caule fastigiatim ramoso, foliis ovato-oblongis acuminatis
V. e basi ovata gradatim subulato-acuminatis carinatis nervo percunente, seta perbrevi, tbeca elbptica, operculo
rostrato. (T a b . LYII. Fig. IX.)
H a b . Campbell’s Island ; on alpine rocks.
Caules laxe cæspitosi, superne fastigiatim ramosi, suhrigidi. Folia erecto-patentia, subrecurva, margine basi
reflexa, forma sat varia, superiora longiora, apice suhdiaphana, vix pUifera, nervo vahdo continuo instructa, flavo-
viridia. siccitate erispatula erecta; pei-ichætialia breviora, eUiptico-oblonga, obtnsa v. acuta. Seta vix Hneam longa,

oonico-mitrmformis, subplicata, costata, fusca, basi lacera et inflexa, operculo paulo longior. Ammlus painrs.
The foliage of tliis moss hears a considerable resemblance to that of Bacomitrhm fasciculare, from which it
differs in the very short seta, pale eUiptical theca, and in the peristome being truly that of a Drggtodon.

I I a b . Campbell’s Island ; amongst tufts of grass at the foot of precipices, rare and barren.
This does not appear' to differ from European specimens.

7. ORTHOTRICHUM, Hedw.
Peristomium simplex v. duplex, rarius nullum; exterius dentes triginta duo, geminatim v. bigemiiiatim coadunati,
(hinc quasi octo v. sedecim apparent) ; inierius ciliæ octo, æquales, v. sedecim, altcrnis brevioribus, erectis v.

lanceolato-subulatis obtusis camosis nervo crasso subcontinuo, theca breviter exserta pjuriformi lævi, peristomii
dentibus sedecim, ciliis nullis, caljqitra glabra. (Tab. L Y II. Fig. A^III.)

H a b . Lord Auckland’s gi-oup and Campbell’s Is lan d ; on rocks and stones immediately above high-
water mark. Yar. jS, CampbeU’s Island, with the foUowing species.
Caules pulvinati, 2-4 lin. longi. Folia suberecta, crassa, coriacea, supra plana, apice subobtusa, marginibus
basi inilexis, nervo crasso infra apicem evanido, siccitate paulo incurva, oUvacca v. fusco-lutea, demum nigricantia,

Perhaps aUied to the O. psychrophilum. Montagne (Aim. Sc. Nat., vol. ix. p. 52) ; but the leaA'Cs are more erect
Avith theh margins not reflexed, the capsule even, of a thicker texture, and there is no inner peristome. I t bears
some resemblance to the 0. Magellanicum, Mont., from which the same characters w'iU also distinguish it. The dry
foliage is of an almost horny consistence.
