Falklands, etc.] Hab. Falkland Islands, on the moors, (barren). Hermite Island, Cape Horn, (barren).

Evidently the British species, and a very widely dispersed one. 3. Polytrichum alpestre, Hoppe; Bridel, Br. Univ. vol.ii. p. 140. P. juniperinum, var. Hook, et Tayl. I. c. p. 45.

Hab. Strait of Magalhaens, Port Famine, Cap/. Kin//.

This, which is also a British species, has been collected by Capl. King only.

4. Polytrichum pilifermn, Sckreb.; Sclneaegr. Supjrf.I. vol. ii. p. 313. t. 153. Hook.et Tayl. I.e. p. 44. t. 10.

Hab. Falkland Islands, not uncommon on the moors, rare in fruit. Affecting the same locality and habit in the Falklaiids that it does in England.

5. Polytrichum dendroides, Scbwaegr. Suppl. II. vol. ii. p. 2. 1. 151.

Hab. Strait of Magalhaens, B ' Urville. Hermite Island, in the woods, on steep banks by rivulets, not uncommon, but rare in fruit. In fertile specimens the branches are arranged at intervals around a common axis, the lower ones usually sub-divided. The peristome has some analogy to that of Lyellia, the teeth being very small and the connecting base remarkably thick and prominent. The calyptra is quite glabrous. Columella apparently winged. In habit this moss belongs to Pogonatum of Bruch and Schimper, but its other characters do not correspond.

6. Polytrichum squamosum, Hook. fil. et Wils.; caule elongato squamoso fastigiato-ramoso, ramis patentibus brevibus densis curvatis, foliis dense imbricatis erecto-patentibus lanceolato-subulatis strictis serratis. (Tab. CLIII. fig. VIII.)

Hab. Hermite Island, on the hills at an altitude of 1,000-1,500 feet, scarce and scattered, always barren.

Caulis subspithameus, ascendens, flrmus, subflexuosus, atro-purpureus, maxima ex parte hunio sepultus, triqueter, superne squamis appressis luteo-fuscis scariosis nitidis in folia caulina gradatim abeuntibus vestitus, apice dendroideo-ramosus; rami vix semiunciales, subsimplices, patentes, fastigiati. Folia dense conferta, suberecta, ad apices ramorum subsecunda, siccitate appressa, e basi membranacca pellucida semiamplexicauli lanceolato-subulata, vix trilinearia, superne lamellata, dorso carinaque scabra.

Although this moss is very different in aspect from P. dendroides, the characters seem scarcely sufficient to distinguish it. The short straight leaves are only half as long as in that species. Plate CLIII. Fig. VIII. — 1, plant of the natural size ; 2 and 3, leaves : — magnified.

7. Polytrichum Magellanieum, Hedw., Sp. Muse. p. 101. t. 20. Fl. Antarct. pt. 1. p. 132. t. lix.

Hab. Strait of Magalhaens; It Urville, Hombron.

Hermite Island, on fallen trunks of old trees, &c., in the woods ; also on alpine rocks, in clefts. Falkland Islands, not uncommon on the ground and in clefts of quartz rocks on the hills, (always barren).

19. CONOSTOMUM, Sw.

1. Cokostomum australe, Swartz, Schoaegr. Suppl. II. vol. i. p. 108. 1. 130. Fl. Antarct. pt. 1. p. 182, Hab. Hermite Island, on open rocky ground on the hills, occupying the same situations as C. boreale in Europe. Falkland Islands, in similar localities, bearing fruit in November.

Entirely the representative of the British and Arctic C. boreale. Also found in Lord Auckland's group.
