Very closely allied to the /. serrulata, Sw. (Muse. Exot. t. 88), of the West Indies, but the leaves are not so densely imbricated, are scarcely serrulate, their areolae are more minute, and the stipules are different. When growing in moist places the plant is greener and larger, and the leaves more generally serrulate than when found in drier situations.

Hab. Herrnite Island, Cape Horn ; on the trunks of trees in the woods.
Caspites parvi, inter Muscos aliasque Hepaticas nidulantes, rufo-brunnei. Caules unciales, vage sed parce ramosi, basi nudi, sursum curvati. Folia arete imbricata, oblongo-rotundata, madore e margiuibus incurvis tumida, opposita, basi antice connata, postice cum stipula adnata. Stipula ovata, bifida v. varie secta, segmentis subulatis.
The form of the leaves, then- opposite arrangement and connexion in front, are similar to J. Brankiana, Nees, but that species is destitute of stipules.

35. Jungermannia otvphylla, Hook. fil. et Tayl.; caule debili flavido elongate subramoso, foliis oppositis secundis erecto-patentibus imbricatis flavidis et membranaceis late reniformi-rotundatis basi latissime cauli adnatis integerrimis, margine superiore basi tumido recurvo, stipulis majoribus concavis late rotundatis emarginatis integerrimis obscure sinuatisve.

Hab. Herrnite Island, Cape Horn ; in alpine bogs.
Caspites laxi, luride olivacei v. albescentes. C'aidis gracilis, 3 una longus, parce ramosus ; ramis erectis. Folia tenuissime membranacea, latissime oblonga v. rotundata, basi ad marginem auteriorem quasi auriculata. Stipula ampla?, subimbricata;, margiuibus incurvis, apicibus emarginatis, sinu lato, nunc apice sinuato. In habit and general appearance this approaches our J.palustris, which inhabits similar localities, but they are in many respects widely different plants.
