316 MR. H. М. DIXON ON A 
secondary branchlets very frequently suppresed, so that the stem appears 
pinnate only or slightly bipinnate, not frondose as usual ; but some stems are 
quite normal, and show it to be a state merely. 
HYPNACEZ. 
CTENIDIADELPHUS SPINULOSUS (Broth.), Fleisch. MS. (Сатруйит spinu- 
losus, Broth. in sched.). Jungle, Sekong, e.fr. (Nos. 97, 109), det. Fleischer. 
This is an undescribed species, for which, with //ypnum Plumularia, 
C. Muell., Fleischer proposes the new genus Ctenidiadelphus. 
EcrRoPoTHECIUM, Mitt. 
This large and very difficult genus reaches one of its culminating points 
in the Western Pacific ; a large number of species have been described in 
recent years, and I have received several from the Solomon Is, New 
Hebrides, and elsewhere which I am not able to refer at present to any 
species known tome. ‘The absence of fruit also frequently renders it unsafe 
to attempt determination. I have thought it best to leave one or two of 
Mr. Binstead’s plants undetermined for this reason. 
E. Monirzi (C. Muell, Jaeg. Shaded rocks near stream, Sapong, near 
Tenom, c.fr. (No. 202); Rundum, leg. E. О. Rutter (No. 231); Sadong, 
Sarawak, leg. J. H. Cranston, 1901 (No. 49). 
E. DEALBATUM (Hornsch. & Heinw.)?. Damp rocks by railway, near 
Tenom (No. 195). A doubtful plant. According to a letter received from 
Fleischer, several different plants figure in the herbaria under this name. I 
sent this (No. 195) to him with another specimen from Coconut L., near San- 
dakan c.fr. (No. 59), upon which plants he writes that No. 59, Е. dealbatum? 
is not identical with the Мурпит dealbatum of the Bry. jav., nor with 
Н. dealbatum of С. Mueller's Synopsis, nor with E. dealbatum ex herb. Mitt. 
from Toegoe (Java), with which latter Mr. Binstead’s No. 195 agrees. But 
which of these accords with the original of Reinwardt is uncertain, and can 
only be settled by comparison with that author's own specimens, which he 
has so far been unable to see. 
ECTROPOTHECIUM sp. Coral rock, Simporna, c.fr. (Nos. 130, 132). Very 
near No. 59 (E. dealbatum ?), but slightly more robust, the leaves rather 
broader, less finely pointed, perichætial leaves rather longer and finer. 
E. MONUMENTORUM (Duby), аер. Decayed tree-roots, rubber plantation 
near Sandakan, c.fr. (Nos. 51, 61) ; Coconut Т., near Sandakan, on coral 
sand in shade, с.Ёг. (No. 137) ; rotting log by streum in shade, Sapong, near 
Tenom, c.fr. (No. 206).
