to his L. incanum at all. The only two plants in his herbarium, as Mrs. 
Britton informs me, under the cover of L. incanum, are ““D. Steb 
Kirk ; Gt. Barrier Id., N.Z..” the latter being unnamed. Sinclair’s New 
Zealand plant is included in Mitten’s herbarium under Sclerodontium Sie- 
as given are equally sopEaable to that species. It may also be remarke 
that incanum would be a peculiar name to give to a species which was 
distinguished principally by the absence of hair- -points ! 
Hooker’s own specimen, however, and Hutton and Kirk, No. 72, are 
of quite a different aspect, colour, and habit, and Hooker’s plant is tai 
marked in the character of the hair- -point. Hutton and Kirk 
ever, with the habit of Hooker’s specimen, has the hair-point very stow 
and scarcely developed. It is therefore intermediate between D. Sieberianum 
and D. incanum, and I am inclined to think it may ultimately be found 
that D. incanum is rather to be retained as a varietal form of D. Sieberianum 
than of specific ran
