This plant has so many points in common with /. heteropkylla, Schrad., that we retain it as a separate species with much hesitation, and chiefly on account of the larger cells of its more rounded leaves, which are more gibbous above and narrower towards the apex ; the broad stipules, which are never ovate, and also on account of the longer calyx, of which the lips are more frequently and deeply toothed, as are the perichsetial leaves. Through a mistake the specific character and description of /. intortifolia, nobis, were repeated under this species in the 'London Journal of Botany,' vol. iii. p. 381.

Pallide flava v. albo-virescens, inter alias Hepaticaa repens. Caulis i unc. longus, apicem versus attenuatus recurvus, antice canaliculars. Folia arete imbricata basi latiora antice approximata, margine inferiore longe decurrente, sinu obtuso, segmentis acumiuatis divaricatis, cellulis inajusculis laxis pellucidis. Stipule plerumque conformes, pro genere maxima;, basi concavae, amplexicaules, in lacinias sex erectas v. divergentes subulatas fissae. Anthera inter baseos foliorum perigonii parte superiore caulis sitae, pedicellatse, albas, majusculae. A highly beautiful species and very different from any we have ever seen. The apices of the leaves are rather variable, in general they are bifid for i or i way down, with a rounded sinus ; but, in other cases, the segments have more the appearance of subulate appendages placed on each of the rounded apices of the leaf; in one instance a trifid leaf was observed, the third segment was on the upper margin towards the base.
