404 NEW HEPATIC/E. 



decurved mouths pointing outwards, and reaching below the 

 ventral margins of the leaves. Fissure of the stipules close, 

 inconspicuous. Calyx three times as high as the pericluetium. 

 This differs from our F. microscypha by the smaller size, the 

 more minute cells of the leaves, by the acute sinus of the 

 stipules, and by the acuminate auricles of the perichsetial 

 leaves.

 formibus folii partem tertiam aequantibus ; stipulis minutis, 

 ovatis, bifidis ; perigoniis late linearibus ; calyce majori, 

 terminali, obcordato, compresso, lsevi, angulis sursum sub-

Inconspicuous, very pale green. Stems scarcely 2 lines 

 long. Perichaetial leaves nearly round, their auricles lanceo- 

 late with the margins reflexed, interiorly having a minute 

 spine. Both perigonium and calyx large in proportion to the 

 stems and leaves. It is far more minute than F. Atchafalaga, 

 Hampe, and has the leaves more distant, with smaller cel- 

 lules, and the segments of the stipules entire. 



10. F. megalocarpa^ Tayl. ; caule sparso, procumbente, laxe 

 bipinnato, ramis gracillimis; foliis imbricatis, patentibus, 

 oblongo- ovatis, acutis, recurvis, integerrimis; auriculis cla- 

 vato-oblongis, cauli paralellis, stylo subuliformi interjecto ; 

 stipulis minutis, bifidis ; perigoniis rotundatis, sessilibus ; 

 calyce majori, ramulum terminante, oblongo, supra pla- 

 niusculo, subtus obtuse carinato, tubifero. 



Hab. On Musci. Van Diemen's Land. Dr. Grevilte's Herb. 

 Minute, scattered, brown. Dioecious. Stems scarcely 1 

 inch long. Shoots of equal breadth. Both perigonia and 

 calyces large in proportion to the shoots. It is more minute 

 and slender than F. exilis, Tayl. from Demerara, and readily- 

 distinguished by the style interposed between the auricle and 

 the stem.
