366 NEW HEPATIC^E. 



about \ an inch long and l-20th of an inch broad ; branches 



few. Some plants are monoicous, having calyces on one 



shoot and perigonia on another ; perigonial leaves imbricated, 



ventricose, with an incurved, tumid process, containing an 



anther at the base, the elongated tops reflexed ; there are at 



least two pairs of erect and ciliated perichsetial leaves. On 



the calyx a lanceolate wing is on each of the three angles, and 



has 3-4 spinous cilia. This has the habit of L. leucophylla, 



Tayl., but is a greener and somewhat a larger species ; the 



leaves are far narrower at their bases and nearly entire. 



2. L. pertusa, Tayl. ; caule implexo, adscendente, sub- 



ramoso ; foliis imbricatis, patentibus, triangulari-ovatis, 



margine subflexuoso, bidentatis, subintegerrimis, in stipu- 



lam subrotundam, 4-dentatam utrinque abeuntibus ; calyce 



terminali, lineari-oblongo, trigono, anguste alato, apice 



spinoso-dentato ; foliis perichaetialibus 3-4-dentatis. 



Hab. Rio de Janeiro ; n. 43. Gardner, Hook. Herb. 



Patches wide, pale olive-green. Stems about 1 inch long. 

 Leaves with a shallow sinus near their junction with the sti- 

 pule, sometimes tri-dentate. Calyx twice as long as the 

 leaves, with a very narrow wing on each of the two inferior 

 angles. Stipules oblique. Capsule linear-oblong. Differs 

 from L. connata, Swartz, by the 4-dentate stipules, by the 

 narrow wing to the calyx, and by the perichsetial leaves 

 having 3-4 distinct teeth. 



3. L. hirtifolia, Hook. fil. et Tayl. ; caule disperso, procum- 

 bente, subsimplici; foliis subimbricatis, patentibus, re- 

 curvo-concavis, late ovatis, obtusiusculis, subdenticulatis, 

 celluloso-hirtis, in stipulam subquadratam, 4-laciniatam 

 utrinque abeuntibus. 

 Hab. With Sticta chloroleuca, Hook. fil. et Tayl. Van Die- 

 men's Land. 



Patches very loose, plants usually scattered. Stems scarcely 

 } inch long, slightly bent ; shoots tumid on account of the 

 recurved leaves, pale green. Leaves rotundato-ovate, mi- 

 nutely tomentose from the projection of the cells, very irregu- 

 larly and sparingly denticulate at the tops. Allied to L. mu-
