Van Diemen’s Land, Gunn, 1832, No. 1002, in herb. Hook. 
This species forms massy and compact tufts of a brown-green, or 
black-green colour, growing in company with Chara australis. The 
Specimens being too much advanced in maturity and scarcely bearing 
fructification, I could not decide whether it was dicecious or mone- 
cious. In the last case it will be difficult to separate it from the more 
condensed varieties of N. gracilis, a species which is spread over a large 
part of the earth. The seeds are scarcely "ys = those of N. tenu- 
issima ; the brown nut has the length of .25— 
B. heterophylle, ut supra. 
In Europe there is only one species of this division, namely N. AyaZiza, DC., 
a species which was long confounded with N. tenuissima. The New Holland species 
of this division are more numerous.

Swan River, Drummond, No. 8, in herb. Hook. 
This species resembles the less and more condensed forms of N. tenu- 
issima, having, however, still smaller whorls. In some characters it 
approaches to N. microphylla and gleostachys, but by the smaller leaves 
between the large in the inferior whorls it is allied to the following 
species. The male plant has a different appearance from the female, 
the whorls being less and more distant. The seeds are somewhat 
larger than in the preceding ; the dark-brown nut with sharp angles is 
about .34 m. long.
