The New Guinea plant is undoubtedly one of the forms or deriva¬ 
tives of C. leptopoma (Schwaegr.). Fleischer (Musci der Flora von 
Buitenzorg, iii. 1048) considers C. leptopoma , C. muricatum Bry. jav., 
and C. orthorrhynchum (Doz. & Molk.) as segregates—with diffi¬ 
culty defined—of a single aggregate species, and the present plant 
strongly supports that view. It is perhaps nearest to C. leptopoma , 
but it is in some ways intermediate between that and C. muricatum ; 
and I have received an exactly similar plant from the Malay 
peninsula. 
C. elegans Geh. Sogere, 3500 ft., on branches of trees, 20.

Sogere, 2500 ft., on branches of 32. 
A very interesting discovery, the plant (the sole species of the 
genus) being only known from its original station in Borneo. The 
present specimen, though fragmentary, and with only a single seta, 
agrees exactly with the original plant; the narrow leaves with 
bigeminate denticulation above, and the sporophyte characters, being 
identical, while the long, hyaline, jointed, filamentous gemma3, tufted 
among the upper leaves, are very conspicuous.
