Falklands, etc.] FLORA ANTARCTICA. 433 



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.

 and stipule , 4 and 5, stipules : — magnified. 



35. Jungermannia otvphylla, Hook. fil. et Tayl.; caule debili flavido elongate subramoso, foliis oppo- 

 sitis 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. Nobis in Lond. Journ. Bot. vol. iii. p. 466. (Tab. CLVIII.

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.
