90 HEPATICÆ ANTARCTICÆ, 
minute, paler, has leaves less deflexed, while the stipules 
are nearly circular and not kidney-shaped as in the Javanese 
species. 
24. J. acutiloba, n. sp.; caule laxe implexo prostrato ramoso, 
ramis brevibus patentibus, foliis arcte imbricatis patenti- 
bus oblongo-rotundatis concavis integerrimis lobo in- 
feriori minute ovato subdentato involuto, stipulis majo- 
ribus imbricatis rotundatis  subemarginatis, foliorum 
perichetialium lobo inferiori acuminato, calyce oblongo- 
cordato. 
Has. St Helena. 
Patches closely adhering to bark, wide, blackish-green, 
the younger pale olive. Stem more than 1 inch long, irre- 
gularly branched. Leaves crowded, slightly deflexed ; the 
perichetial dentate, erect, the stipules emarginate. 
Allied to the European Jung. Mackaii, Hook. Its stems 
are thicker, the lower lobes more minute, the stipules far 
larger, while the lesser lobe of the lateral perichetial leaves 
is acuminate. | 
25. J. microscypha n. sp.; caule procumbente vage ramoso; 
ramis patentibus, foliis imbricatis patentibus rotundatis 
concavis integerrimis margine inferiori loboque minori 
oblongo involutis, stipulis majoribus oblato-rotundatis inte- 
gerrimis, perigoniis oblongis, calycibus in ramos brevissimos 
terminalibus oblongo-cordatis tumidis triquetris tubi- 
feris. 
Has. St Helena, with Parmelia leucomela, Ach. 
Stems straggling among Mosses; shoots pale olive, scarcely — 
half an inch long; branches few, leaves densely and minutely 
cellular. Perigonia twice the length of the full grown leaves. 
Calyx on a short perichætial branch and so appearing lateral, 
about as long as a full grown leaf, several may be seen on 
the same shoot in a close series. From Phragmicoma Mackat, 
Nees, this is readily distinguished by the smaller cells of the 
leaves, by the more concave leaves, by the greater length of 
the lesser lobe, by the larger stipules, and by the narrower, 
mere tumid and less exserted calyx.
