NEW HEPATIC^E. 405 



11. F.diplota, Tayl. ; caule exiguo, rufescente, implexo, pro- 

 cumbente, subhipinnato, pinnulis laxis ; foliis laxe imbri- 

 catis, patentibus, amplexantibus, subquadrato-rotundatis, 

 integerrimis, apice subrecurvis, margine dorsali gibboso ; 

 auriculis ex angusta basi oblongis, obliquis, ultra folii basin 

 demissis, stylo breviori lanceolato interjecto ; stipulis dis- 

 tantibus rotundato-ovatis, bifidis, integerrimis. 



Hab. On Parmelia sulcata, Tayl. Interior of New South 

 Wales. R. Cunningham, 1836. Hewett Watson, Esq. 

 Stems about 4 lines long. Leaves very thin. The style 

 between the stem and the auricle is scarcely more than half 

 as long as the latter. The cells of the leaves near their junc- 

 tion with the stem are much larger than elsewhere. This is 

 more minute than the Europeean F. fragilifolia, Tayl., the 

 absence of moniliate opaque cells in the leaves and the double 

 auricles at once distinguish them. 



12. F. ulotricha, Tayl. ; caule caespitoso, adscendente, sub- 

 pinnato ; ramis brevibus ; foliis imbricatis, patentibus, 

 oblongo-ovatis, obtusis, convexis, apice recurvis, integerri- 

 mis ; auriculis cylindraceis, cauli adpressis, folio inclusis ; 

 stipulis oblongo-ovatis, emarginato-bifidis, segmentis acu- 

 tis, conniventibus, margine incurvis ; foliis perichsetialibus 

 erectis, ovalibus, acutis, dentatis, eorum auriculis folioque 

 stipulari 3-4-fidis, elongate ciliatis, ciliis crispis; calyce 

 majori, exserto, oblongo, triquetro, nitido, tubifero. 



Hab. South America ; n. 102. Humboldt, Hook. Herb. 



Tufts several inches wide, purplish-black, somewhat shin- 

 mg. Stems 2-3 inches long. Leaves oblong, patent or 

 deflexed. Auricle narrower above, bulging below, slightly 

 curved, not passing down below the margin of the leaf. Sti- 

 pules closely adpressed to the stems. The elongated, nume- 

 rous, crisped cilia of the auricle and stipule of the pericJuetium 

 separate this species from its congeners. 

 1 3. F. exilis, Tayl. ; monoica ; caule implexo, procumbente, 

 subbipinnato ; ramis gracilibus, recurvis ; foliis imbricatis, 

 erecto-patentibus, oblique ovatis, obtusis, apice minute
