H.1B. Falkland Islands; on shady clay-banks near the sea, at Po rt Louis (bari'en). Hermite Island •
common on mossy banks aud on tbe trunks of old trees in tbe woods of evergreen beech, abuudant in fruit!
Very closely allied to EooUna pulcMla, nobis (part 1. p. 142. t. kdi) ; but the leaves are more ereet less
crowded, acuminated, with larger reticulations, thecæ larger and decidedly cernuous. The caK-ptra in both these
species is fringed at the base.

31. HYPOPT'ESYGIUM, Bridel.
Onr reasons for not having previously admitted this genus wiU he found in the former portion of this work
V e have seen since, that the male flowers are occasionaUy, though rarely, inserted beneath the accessory leaves, and
therefore we retain this name for a genus which certainly claims to be separated as well from Leskia as from
Hookeria.

H a b . Hermite Is la n d ; in wet places on the ground, very common in th e woods, forming lai-ge green
patches (always barren).
Under Leskia tamarisdna two species have been confounded by Hedwig (Sp. Muse. p. 212). The name
ought to be appUed to the present moss, if the inconvenience of changing names generaUy received did not forbid.

Om- specimens are not so large as those described by P. de Beauvois, tbough eiddently belonging to the same
species. Dr. Montague has properly remarked that this species differs from H. laricinum in the flabeUiform, not
pinnate, disposition of its branches, which nU spring from one central point and take a horizontal direction. FertUe
specimens from Colchagna, in Chili, have also a more pendidous oblong capsule and shorter operculum.

Allied to tho Scottish J. concinnata, Lightf.; but readily distinguishable by the stems not being tufted, the shoots
sleiidei- and flexile, the larger more cellular leaves, which are far more deeply divided, and have lanceolate seg-
