Wliole plant obscure, blackish-greeu. Allied to P. denticulatum and P. nigellum, but with its lateral leaves
very much narrowed towards the base, and these, as well as the intermedial and medial, of a different form. Tlie
species of this genus, from the neglect iu their descriptions of the very different forms of the leaves iu the several
series, are hardly intelligible. Miiten, I. c.— P la t e CLXXVII. Fig. 4 ; 1, portion of branch and leaves ; 2, 3 , and

(Auctore Gul. Mitten, A.Tj.S.)
The Tasmania!! Hepaticoe, of which 126 are here enumerated, present a few species which appear to
be peculiar to the Island, the remainder being found iu New Zealand and Fuegia. One-third of tbe species
included in tbe Flora of New Zealand bave not yet been found in Tasmania; of these some, as
Plagiochila Stephensoniana, P. Arbuscula, P. gigantea, and Madotheca Stangeri, are so large that they
would scarcely have been overlooked if they were so generally distributed in Tasmania as tliey appear to
be in the islands of New Zealand. The larger species of Lejeunia seem also to be absent, and Riccia has
no representative. I t can hardly be supposed (hat these are entirely wantiug in Tasmania, but their absence
from the collections yet received shows that if present they are rare. As in the Flora of New Zealand,
there occur here also some species described by Dr. Taylor, of which nothing further is now kuown ;
his descriptions and remarks have therefore been inserted in their respective places in the arrangement,
which is the same as that adopted in tlie ‘ Flora of New Zealand.’
