A small species, often not much longer thau C. echinellus, «nth rarely branched stems, aud leaves of a firm
texture, not altered in form or dii-cction by drying. The original specimens of C. combinatus, kindly lent by Nees

It appears th.it. although Dr. Taylor first distinguished this from 0. saccata, he had afrenvavds misgiidugs
that it was but a slate ot the same species, for nohvithslaudiiig the p e a t difference iu appearauce between the sped-
mens ot G. tenella iu Herb. Gresdhe, aud the larger states ot G. saccata, differences for the most part owing to the
Bubbidentate leaves and empty cells in the oiiginal specimens, afi those received from New Zealand nnd Tasmania,
although having the le.aves ot the s.ame torm, have the ceOs more or less replete with colouring matter, and agree in
colour and substance with those ot G. saccata, there being in reahty no difference between the two in the sise of
the cells. It is greatly lo he desired thnt G. saccata, G. tenella, and G. Urcilkaaa should be carefuDy observed in
their phiccs of p o r f i , tor it appears hy no means improbahle that they are but different slates of the same species.

Although the perfect torus of this species is yet wanting, there are sufficient indications present in the specimeus
to warrant its being placed in this geuus. The stipules, overlooked in the description of the plants in the
‘ Synopsis Ilepaticarum,’ are uevertheless present as well in the specimen kindly contributed by Dr. Lehmauu as in
