NEW HEPATICE. 377 



6. R. pocillifera, Tayl.; caule implexo, procumbente, vage 

 subpinnato ; ramis brevibus, subpatentibus ; foliis laxe 

 imbricatis, patentibus, rotundatis, integerrimis ; lobulis 

 minutis, cauli adnatis, subquadratis ; pericheetio axillari, 

 sessili ; calyce abbreviate, campanulato, ore latiori cora- 

 presso, truncato, minute atque obsolete crenulato. 



Hab. St. Domingo. Dickson. 1814. 



Patches wide, pale olive- green. Stems scarcely 1 inch 

 long. Leaves concave, nearly round, patento-recurved. Lo- 

 bules minute, their interior margin lying on, but not passing 

 the stem. Calyx singularly short, resembling in outline an 

 equilateral triangle, the mouth wide, compressed, its crenula- 

 tions observable only under a high power of the microscope. 

 It is related to R. pallens, Sw., but is a smaller plant ; its 

 calyx is at once distinctive. 



7. R. strangulata, Hook. fil. et Tayl. ; caule exiguo, implexo, 

 procumbente, subpinnato ; foliis imbricatis, patenti-recur- 

 vis, rotundato-obovatis, integerrimis ; lobulis minutis, ex 

 curvata tumente basi apice angulatis, cauli adpressis ; 

 perigoniis quadrato-oblongis, in surculorum cursu sitis 

 atque surculo angustioribus. 



Hab. New Zealand. Dr. J. D. Hooker. 1840. 



Patches small, olive, pale. Stems scarcely exceeding three 

 lines in length. Leaves slightly overlapping; their cellules 

 very minute ; the perigonial smaller and rounder, their lobule 

 swelling and containing the anther. This species is remark- 

 able for the short perigonia occurring in the course of the 

 shoots, and nearly upon all the shoots. Branches are 

 scarcely \ of a line wide. This is unlike any species with 

 which we are acquainted, and has the size and habit of our 

 common Lejeunia serpyllifolia, Nees. 



8. R. Miqueliana, Tayl. ; caule implexo, procumbente, debili, 

 pinnato ; foliis laxius imbricatis, patentibus, oblongo-ovatis, 

 obtusis, planiusculis ; lobulo caulem amplexante, apice 

 obtusiusculo, patenti-recurvo ; calyce axillari, lineari-ob- 

 longo, ore truncato.
