Campbell's Islands] FLOEA ANTARCTICA. 153 



27. Jungermannia vertebralis. — Scapaiiia? vertebralis, Gottsche, Bind, et Nees, Synops. Hepat. 

 p. 72. 



Hab. Lord Auckland's group ; on trees, very rare. 



Our specimens of this beautiful species are smaller, but otherwise they coincide with those of Tasmania. It is 

 very closely allied to the /. c/doroleuca, nobis, from Cape Horn, and also to the /. demifolia, Hook. 



(7. Gymnanthe, Tayl., subgenus novum.) 



Receptaculum commune terminale, descendens, obconicum. Calyx nullus. Capsula quadrivalvis, seta suffidta. 

 Elateres spirales seminibus imnrixti. Anthem in fohoruin axillis Hberse, pedieellatae. — Stirps exstipulata ; perichaetia 

 majora ; folia caulina infirm minima. Tayl. MSS. 



28. Jungermannia saccata, Hook. ; Muse. Exot. t. xvi. J. tenella, nobis in Loud. Journ. of Botany, 

 vol. iii. p. 377, 560 and 579. 



Hab. Lord Auckland's group ; in the woods, abundant. 



The figure of this plant, in the ' Musci Fxotici,' does not well accord with our species, in which the upper mar- 

 gin of the leaf is more produced into a lobe, the apex blunter and sometimes emarginate or even bilobed, the lower 

 margin more recurved and the whole base broader. 



To this group may be added the Jungermannia (Acrobolbus, Gottsche) Wihoni, Nees, and the following. 



29. Jungermannia Urvilleana. — Scapania Urvilleana, Mont, in Toy. au Pole Slid, Bot. Crypt, t. 16. 

 f. 2. et in Ann. Sc. Nat. 1843. p. 247. Gottsche, Bind, et Behm. Syn. Hepat. p. 63. 



Hab. Lord Auckland's group ; mixed with other Hepatica in the woods. 



This species, rather variable in its form, especially of the margins of its leaves, is a native of Tasmania, as well 

 as of Lord Auckland's group and the Straits of Magalhaens, where it was first detected by D'Urville. 



(8. Lophocolea, Nees.) 



30. Jungermannia bispinosa, Hook. fil. et Tayl. ; caulibus procumbentibus implexis subramosis, foliis 

 laxe imbricatis secundis erecto-patentibus oblongo-ovatis v. quadratis obtuse emarginatis bifidisve segmentis 

 divaricatis acuminatis basi lata decurrente, stipulis minimis bipartitis segmentis subulatis integerrimis v. 

 utrinque subdentatis. (Tab. LXIV. Fig. VII.) 



Hab. Campbell's Island; on moist ground and trunks of trees in the woods. 



Coespites implexi, 2-3 unc. lati, pallide straminei. Caules prostrati, subflexuosi, graciles. Folia secunda, re- 

 mota, bifida ; stipidis bifidis, rarius midtifidis. 



Very nearly allied to the /. bidentata, L., differing in its smaller size, more remote and suberect leaves, which 

 are narrower, their cellules more minute, then 1 emargination deeper, and in the stipules being less and generally not 

 so compound. 



Plate LXIV. Fig. VII. — 1, a specimen of the natural size; 2, portion of the stem, magnified. 



31. Jungermannia lenta ; Hook. fil. et Tayl. ; caulibus elongatis csespitosis subsimplicibus flexuosis
