HAB. Fraser Hill, Pahang, 4000-4370 ft. alt.; Burkill &

4000 ft.; Holttum (11375). 
E. Moritzii is said by Fleischer to be a rare species in Java, 
and I have no Javan specimens in my herbarium. It is however 
a common plant in Borneo, and on the Malay Peninsula, and I 
have numerous specimens from both of these parts. While 
easily recognized they show a considerable amount of variation 
in the leaf form and direction, as well as in the degree of glossiness. 
One form especially has the branch leaves very different from 
those of the typical plant as figured in the Bry. Jav. (though 
it is referred to by the authors in their diagnosis—“ramulina 
similia vel oblonga, brevius acuminata’’), being almost straight, 
and complanate, scarcely or not at all falcate or decurved, widely 
spreading, very shortly and sometimes quite widely pointed; 
in this case they are usually brown, scarcely at all glossy, with 
shorter, opaque cells and the marzinal row especially short and 
markedly differentiated. The plant is in this case very markedly 
different from the type (so much so that an extreme form of it 
(Singapore, Ridley, No. 203) has been named Chaetomitrium 
Ridleyi Broth, MS. in sched. !); as a rule however some branches 
show the more normal form of leaf, and—together with the 
fruiting characters—establish identity with E. Moritzii. 
E. Moritzii is described in the Bry. Jav. as “‘nitidula,”’ by 
Fleischer as ‘“‘wenig glanzend.’”’ This description is applicable 
to the usual forms, though here and there a plant, or part of a 
plant, shows a decided gloss. In the present variety the branch 
leaves are exceedingly glossy, and in their extreme form of a 
pale or quite white colour; they are much narrower than usual, 
and strongly decurved-falcate, with fine, subulate or almost 
filiform points; the areolation is much more pellucid, of longer 
cells, with the marginal cells not or scarcely differentiated. 
The first specimen I received of the variety showed only a few 
sterile scraps mixed with Trichosteleum, &c., and showed no 
resemblance whatever to E. Moritzii; it was in fact, to all intents
