Obs. The species of this genus may all be considered rare in the 

 Pyrenees. L. 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 

 Hooker'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-
