232 Dixon: New MossEs FROM MALAY PENINSULA 
Seta circa 1 cm. alta; calyptra angusta, basi subinflata, 
supra longe aciculata; theca erecta, 1.5 mm. longa (deoperculata), 
anguste elliptica, operculo longiore aciculari. 
HAB. Petaling, Selangor, 1898; Ridley (772). 
Nearest to S. undulatus and S. Junquilianus, but with a 
very marked difference in the leaf apex; the lingulate, undulate 
lamina quickly contracted into a straight, acute, narrow, sub- 
tubular, cuspidate acumen of varying length, frequently tipped, 
in the upper leaves, with gemmae. The hyaline border reaches 
usually to about the base of this acumen. 
It is possible that it may prove to be a varietal form of S. 
undulatus. 
Note on Calymperes setifolium Hampe. 
Calymperes angusiatum Broth. n. sp. in sched. Hab. Tapah, 
Perak, 1908; Ridley (149). Thisiscertainly C. setifclium Hampe. 
This species, and C. aeruginosum Hampe belong to a small 
Section of Machrimanta (consisting of two or three species only) 
having the leaves markedly constricted above the leaf-base and 
below the lamina, so as to form a sort of waist; this being especi- 
ally noticeable in the upper, ‘‘abnormal’’ leaves, where the 
lamina cells are often reduced to an exceedingly narrow strip 
on either side of the nerve. Brotherus in his Key,—following 
Bescherelle—puts C. aeruginosum in a group with the margin 
at shoulder toothed. Bescherelle, it is true, describes the leaves 
as toothed in the upper part, and with the marginal cells at 
shoulder ‘‘dentiformes;’ the latter character, however, is con- 
trasted with “acute serratae” in C. sevifolium, and does not 
imply, apparently, a high degree of dentation. But Hampe’s 
specimens do not appear to bear out even this, and I am not 
able to explain the statement. 
The figures of the leaf in Lacoste, Sp. Nov. vel Ined. Musc. 
Arch. Indici, Tab. V, show the leaf-base quite entire, and all the 
leaves I have examined of Hampe’s type bear this out. In the 
present species (C. setifolium) the marginal and submarginal 
(perhaps representing the teniole) cells of the leaf-base remain 
elongated not only to the shoulder, but in a very narrow, 1-2 
seriate border almost to the apex. The apical part of the leaf 
margin also is usually distinctly toothed, while in C. aeruginosum 
the leaf apex is quite entire or only very faintly toothed at the 
extreme tip.
