Himantocladium nanum sp. nov. 
Flowers and fruit unknown: plants very small, the 
primary stems creeping, the secondary erect, IO-I5 mm. 
high, without paraphyllia, quite regularly pinnately 
branched with the lowest branches sometimes the longest 
and again pinnately divided; secondary stem leaves in 8 
rows, slightly complanate, asymmetric, mostly recurved 
on one side toward the base, 0.6—.7 mm. long and about 
.4 wide, ovate, the upper part broad with the apex mostly 
rounded and the margins nearly entire or very minutely 
serrulate or papillose to below the middle; branch leaves 
like those of the stem but smaller, the terminal leaves about 
0.25 mm. long; costa smooth, ending 6-8 cells below the 
point - ‘the leaf, sometimes sending off short branches 
from the upper part; cells of leaf with scarcely thickened

Calyptothecium crispulum, April 1905 (3156). 
This species appears to be most closely related to the 
plant called Thamnium parvulum Muitt., from the Neil- 
gherry Hills of India. It differs in being still smaller, with 
smaller leaves, the margins less serrulate and the cells of 
leaf larger than in the Indian species. It has much the 
habit of Himantocladium plumula but is very much smaller 
and the leaves not undulate, broader above, more rounded 
and entire and the cells larger.
