those now before us, from Campbell's Island, are smaller, less branched and various in colour, sometimes for min g small dense tufts, hardly ^ inch in height, but not different in other respects.

3. Andimlea mufabilis, Hook. fil. et Vils.; cauhbus csespitosis elongatis ramosis gracillhnis, foliis confertis laxisve erecto-patentibus rarius falcato-secuudis lanceolatis ovato-lanceolatisve subconcavis enerviis siccitate appressis.

Far. /3, microjofa/Ma ; foliis minimis ovato-lanceolatis. (Tab. LVII. fig. II.)

Hab. Lord Auckland's group; on rocks, at an elevation of 1200 feet; rare, (with female fructification). Campbell's Island; on the hills, in rocky places, from 800-1000 feet of elevation, with male inflorescence only.

Museus polymorphus, ea?spitosus. Canles semi- ad bi-unciales, inferne nudi, supeme ramosi. Folia basi macula flava uotata, dorso vix papulosa, areolis granvdoso-punctatis. Injlorescentia dioica ; folia perigonii ovato-rotundata, acuta, concava. Antheridia 3 v. plura, elliptica, majora longiusque pedicellata quam in affinibus. Paraphyses nulla 1 . Folia perichsetiaha caulinis longiora, elliptico-lanceolata, convoluta.

This species, of which we have no examples in good fruit, differs from A. rupestris in the more erect and narrower leaves. The specific character has been drawn up from an examination of Falkland Island specimens, as well as of those from the Islands now under consideration. The other varieties are enumerated in the London Journal of Botany (vol. 3. p. 536.).

4. Andre;EA sululata, Harvey; caule subramoso, foliis falcato-secundis subulatis attenuates basi clilatatis crassinerviis, perichsetiahbus convolutis. A. subulata, Harvey in llooh. Ic. Plant, vol. hi. t. 201. far. y, pericluetialis ; theca foliis perichsetiahbus rninoribus immersa. (Tab. LVII. fig. I.)

Hab. Lord Auckland's group and Campbell's Island; upon rocks, at a considerable elevation on the hills.

The cauline leaves of this variety are longer and more strict than in the other states of the plant enumerated in the ' London Journ. of Botany' (1. c), and the theca and perichsetium very inconspicuous; we cannot however venture to separate it as a species. It differs from A.Rothii, its nearest ally, in the leaves being longer and the nerve thicker, the latter occupying the whole breadth of the leaf, except at the base, so as to have been overlooked, and the leaves consequently described as nerveless.

Plate LVII. Fig. I. — 1, specimens of the natural size ; 2, a branch ; 3 and -i, cauline leaves ; 5, section of ditto ; 6 and 7, perichsetial leaves ; 8, a theca : — magnified.

2. SPHAGNUM, Bill.

Theca globosa, stomate nudo exannulato. Columella apice libera, abbreviata. Calyptramedio rupta, basi persistente. Vaginula apophysiformis, pedicelliun brevissimum occultans, demum stipitata. Ferichcetium laterale.

Bridel, supposing this genus to be destitute of a vaginula, constituted it a separate order; in which he was followed by Bruch and Sclumper.

The female flower, at first sessile, in every respect like that of other pleurocarpous mosses, occupies the place of a ramulus, or is inserted in the axis of two or more branches. As the fructification advances, the receptacle elongates, and the pericheetial leaves, becoming separated from one another, it presents the appearance of a lateral branch. The antheridia arc found in the fertile plant at the clavate and often discoloured extremities of short deflexed ramuli.
