242 Dixon: New MosseEs FROM MALAY PENINSULA 
and purposes a Stereodon, but it showed such an almost absolute 
resemblance to a South Indian species of Ctenidium recently 
described by me as C. stereodonioides that I gave it the MS. 
name of Clenidium substerecdonioides; and I had indeed actually 
drawn up a description of it for this article under that name, 
when a further consignment of mosses from Fraser Hill threw 
a quite unexpected light upon it. A large tuft of more or less 
typical E. Morttzii showed here and there a branch entirely 
identical with the new species, and I was able to find here and 
there a stem having some or most of the branches bearing the 
short, shortly pointed, complanate, brown leaves, other branches 
being typical, but here and there a single branch with all the 
“stereodontoid”’ characters of the present var. clearly marked 
(one had in fact on a single stem, Ectropothecium Moritzii, Chaeto- 
mitrium Ridleyi, and Ctenidium substereodontoides!). Further 
examination showed some stems with all the branches exhibiting 
the varietal characters, and one or two of them were fruiting. 
Others in the same tuft were nearly typical, and some quite so: 
and it is difficult therefore to draw a clear line between the varietv 
and the type; but the extreme form being so marked and sc 
deceptive, it seems desirable to characterize it and perhaps 
avoid future pitfalls by separating it as a variety. 
PLAGIOTHECIACEAE 
Taxithelium instratum (Brid.) Broth. 
Kurzii Dixon. nov. var. (Hypnum microcladum Hampe 
MS. in herb. Trichosteleum Kurzii Sanesb.: ; Jaeg. Adumbr. II, 450 
nomen). 
A forma typica ae minus dense, maps irregulariter

HAB. Yomah, Sie Kurz (2922). 
This plant was distributed as Hypnum micrecladum Hampe 
MS. (or sometimes, erroneously as it seems, as H. microcladum 
C. M. MS.). It must not be confused with H. microcladum 
Tayl. & H. microcladum Doz. & Molk., both of which belong to 
Rhaphidostegium. 
It is scarcely to be distinguished from Tax. instratum, only 
the leaves are — ee less regularly papillose.
