Falklands, etc. | CRYPTOGAMIA ANTARCTICA: 115 
Our specimens agree with H. lithophilum, except that their branches are more elongated and the leaves 
faintly two-nerved at the base. A Brazilian specimen from Raddi corresponds with the H. succedaneum, which is 
allied to H. molle.

Var. laxum, folis secundis patentibus ellipticis concavis serrulatis enerviis. 
Haz. Hermite Island; in moist places in the woods, and on the hills. 
Caules semiunciales, prostrati, parce ramosi; rami graciles. 
This variety is allied to H. gracile, nobis, but differs in the reticulation of the leaves, and in their margins being 
recurved at the base.

vol. ii. p.382. ; 
Haz. Hermite Island; on wet rocks by streams of water, generally in woods, growing in patches, rare 
in fruit. 
Allied on the one hand to H. tenuirostre, Hook. (Muse. Brit.), and on the other to H. leptorhynchum, Schwaegr. 
From the first of these it differs in the longer more attenuated circinate leaves; from the latter in its larger size and 
in the elliptical shape of the lower part of the leaf, which is not reflexed at the margin. The operculum, as in those 
species, has a long slender beak and is somewhat longer than the capsule.

Has. Hermite Island; very common on the rocks and banks, and on trunks of trees, taking the place 
of H. cupressiforme, which, strange to say, has not hitherto been found in any part of Fuegia or the Falk- 
land Islands.

Allied to Hookeria asplenioides, Schwaegr., but smaller, and having the margin of the leaves thickened and 
undulated when dry. Described from fertile specimens, gathered on the bark of trees, in Tasmania, by Mr. Gunn.
