Obs. The species of this genus may all be considered rare in the 
Pyrenees. LL. bidentata I did not once observe in the higher moun- 
tains, though it occurred at the foot of the low hills near Pau, inter- 
mixed with mosses; yet I can hardly persuade myself that it does 
not ascend higher, and that, being reputed so common a plant, I 
may have passed it by unnoticed. L. heterophylla, another species 
equally frequent with us, I gathered but once in the Pyrenees,

The fructification of this plant is truly lateral (ramulo fertili e 
ventre caulis exeunte), and not as described in ‘ Synopsis Hepatica- 
rum,’ p. 101, ‘ perianthio terminali, mox dorsali,”’ for an instance of 
which I have in vain searched perhaps a hundred fertile stems. The 
involucrul leaves are normally two, with an interposed stipule, and the 
uppermost leaf is concrete with the perianth for one-third of its 
length. The perianth is very thick below (= 3-4 cellules), and should 
perhaps be rather regarded in this part as a hollowing out of the apex 
of the stem. The calyptra is concrete with the inner surface of the 
perianth for more than half its length, as correctly represented in 
Hocker’s figure, but not alluded to in ‘Synopsis Hepaticarum.’ All 
these characters bring this species very close to Harpanthus Floto- 
vianus, N. ab E. (Syn. Hep. p. 170), the sole tangible difference 
being that in the former the perianth is obovate and in the latter 
fusiform, while they separate it widely from Jung. acuta and Ban- 
triensis. If we consult now the organs of vegetation, we find the 
similarity quite as striking. The leaves of H. Flotovianus are biden-
