NEW HEPATICiE. 367 



ricata, Gottsche, from the Cape of Good Hope, which, 

 however, is smaller, has the leaves bidentate and strongly 

 muricate, while the stipules are more minute and simply 

 bifid. 



4. L. subemarginata, Hook. fil. et Tayl. j caule subsimplici, 

 repente, vage ramoso ; foliis imbricatis, complanatis, pa- 

 tentibus, oblongis, retuso-emarginatis, integerrimis, margine 

 ventrali gibboso, stipulis minutis, quadrifidis altero latere 

 connatis; calyce terminali, lineari-oblongo, trigono, ore 

 aperto, trifido, dentato. 



Hab. On bark ; Van Diemen's Land. Gunn, Hook. Herb. 



Patches straggling, brown. Stems 1-2 inches long. Leaves 

 loosely imbricated, thin and largely cellulose, usually with a 

 very shallow, obtuse sinus, yet some of the lower leaves are 

 bidentate or irregular at the apices. Calyx twice as long as 

 the leaves, subtruncate ; perichtetial leaves bidentate. This 

 is a much larger plant than our L. textilis, from Falkland 

 Islands ; the gibbous inferior margin of the leaves, their 

 larger cells, and the deeper division of the stipules, readily 

 distinguish it. 



5. L. polyclada, Hook. fil. et Tayl. ; caule implexo, procum- 

 bente, subsimplici ; foliis imbricatis, patentibus, semicor- 

 datis, obtusissimis, integerrimis, antice subcurvatis ; sti- 

 pulis liberis, ex lata basi 6-ciliatis. 



Hab. New Zealand; n. *]Q. Herb. Mus. Paris, 



Patches wide, close, flat, brown, shining when dry. Stems 

 2-3 inches long, but little branched. Stems black. Leaves 

 curving forwards. Stipules rather large, yet not imbricated, 

 nor connate to the leaves. Closely resembling L. planiuscula, 

 Hook. fil. et T. but the leaves are longer, their anterior 

 margin curved forwards, nor do they diminish in size 

 upwards, and the 6-lacinated stipules are much wider than 

 the stems. 



6. L. divaricata. Hook. fil. et Tayl. ; caule implexo, procum- 

 bente, ramoso ; foliis approximatis, suberectis, secundis, ex 

 angusta basi oblongis, convexis, bifidis, segmentis lanceo-
