NEW HEPATIC^E. 369 



Patches pale olive. Stems 2-3 inches long; branches 

 rather short, fine as human hair, curved downwards, and 

 when dry, variously flexuose. We have not seen L. Sandvi- 

 censis, Ldbg. to which ours must be closely related ; but this 

 is said to have deeply quadrifid leaves on the branches, 

 and the lacinia of the stipules to be obsoletely denticulate or 

 bidentate. 



2. L. humillima, Tayl. ; caule implexo, prostrato, subpinnato, 

 flagellifero ; foliis arete imbricatis, ovatis, bifidis, segmen- 

 tis acuminatis ; stipulis minutis, ovatis, bifidis ; calyce 

 ventrali, ovato-lanceolato, subplicato, ore subintegerrimo. 



Hab. North-west coast of America ? Menzies, Hook. Herd. 



Patches minute, whitish. Stems about 3 lines long ; the 

 older branches with more closely imbricated and larger leaves 

 than the younger or flagelliform shoots. Calyx sometimes 

 situated beneath a flagelliform shoot. Pericheetial leaves 

 longer than the cauline, and with longer segments. Calyx 

 three times as long as the leaves. The bifid leaves separate 

 this species from its congeners. 



3. L. triceps, Tayl. ; caule implexo, procumbente, subpinnato ; 

 foliis imbricatis, patentibus, stipulisque oblongis trispino- 

 sis ; calyce ventrali, lanceolato, sursum plicato ; foliis 

 pericheetialibus concavis, erectis, adpressis, late ovatis, 

 subdenticulatis. 



Hab. Owhyhee. Menzies, Hook. Herb. 



Patches minute, pale olive. Stems scarcely 4 lines long. 

 Leaves rather loosely imbricated, concave. Stipules minute. 

 This is not unlike our common L. reptans, Nees., its leaves, 

 however, are more distant, more concave, and divided into 

 three spinous teeth. 



4. L. attenuata, Tayl.; caule laxe ceespitoso, adscendente, 

 pinnato; ramis secundis attenuatis; foliis laxis, erectius- 

 culis, concavis, quadrato-oblongis, quadrifidis ; stipulis mi- 

 nutis rotundatis, quadrifidis; calyce ventrali, majori, ex 

 angusta basi lanceolato.
