6 C. braunii , known from Hawaii and New Zealand, 
is monoecious with strongly developed stipulodes and 
bract-cells. 
7 C. zeylanica , known to occur as near as New Cale- 
donia and Hawaii, is diplostephanous (two tiers of 
stipulodes) and has branchlets more or less corticated 
but with the basal branchlet segment regularly ecorti- 
cate.

DESCRIPTION OF FIJI MATERIAL: Plants dioe- 
cious, 10-30 cm high, with dull finish when dry. 
Axes 500-980 /x in diameter, slender to mod- 
erately stout; internodes 2-8 cm long, 1-2 times 
as long as the branchlets; cortex none; nodes of 
axes commonly swollen and congested with a 
white material. Stipulodes in 1 tier, 2 per branch- 
let, 0-1 M times as long as the axis diameter, 
slender, commonly up to 600 /x long and 60 fi 
wide and stiffly spreading; widely variable, and 
obscure or absent in some collections. Branch- 
lets , sterile , 5-7 in a whorl, 1-3.5 (-6) cm long, 
undivided, spreading and fairly straight; seg- 
ments 3, the end segment generally 2 -celled with 
the end cell a conical rnucro which is variable 
in length, commonly 350 /x long by 120 ft wide; 
fertile, same as sterile or reduced, where reduced 
may form into terminal or lateral heads (espe- 
cially in $). Bract-cells 0-4 at a node, com- 
monly absent, where present 54-114 times as 
8 N. tenuissima, reported from Palau, has a strongly 
reticulate oospore membrane and forms no heads or 
mucus.
