Hepatice, by W. Mitten.) FLORA OF TASMANIA. . 999 
Pallide fusco viridis. Caulis subuncialis, parce radiculosus. Folia firma, convexa, apice ut plurimum sub- 
truncata, breviter tridentata, rarius bidentata. 
À small species, often not much longer than C. echinellus, with rarely branched stems, and leaves of a firm 
texture, not altered in form or direction by drying. The original specimens of C. combinatus, kindly lent by Nees 
von Esenbeck, are a rather larger species, with soft and flaecid leaves composed of more lax cells. —Pıate CLXXIX.

It appears that, although Dr. Taylor first distinguished this from @. saccata, he had afterwards misgivings 
that it was but a state of the same species, for notwithstanding the great difference in appearance between the speci- 
mens of G. tenella in Herb. Greville, and the larger states of G. saccata, differences for the most part owing to the 
subbidentate leaves and empty cells in the original specimens, all those received from New Zealand and Tasmania, 
although having the leaves of the same form, have the cells more or less replete with colouring matter, and agree in 
colour and substance with those of G. saccata, there being in reality-no difference between the two in the size of 
the cells. It is greatly to be desired that @. saccata, G. tenella, and G. Urvilleana should be carefully observed in 
their places of growth, for it appears by no means improbable that they are but different states of the same species.

Although the perfect torus of this species is yet wanting, there are suficient etm present in the sposi- 
mens to warrant its being placed in this genus. The stipules, overlooked in the description of the plants in the 
* Synopsis Hepaticarum,’ are nevertheless present as well in the specimen kindly contributed by Dr. Lehmann as in
