Swan River, Drummond, No. 9, in herb. Hook. 
One of the least and most delicate species of the genus, resembling 
in its habit a tender N. tenuissima; but the fertile whorls are smaller, 
having in the diameter only about two millim., and invested with a 
tender pellucid jelly, being, however, not so thick as in N. gleostachys 
and gelatinosa. The nut of the seed is red-brown, .30—.32 millim. long. 
. gleostachys; dioica, caule tenui; verticillis sterilibus e foliis 
elongatis, apice brevissime furcatis ; verticillis fertilibus approximatis, 
minutis, capitula elongata spiciformia gelatinosa formantibus, e foliis 
8 infra medium simpliciter vel in uno alterove radio repetito 4—5-fur- 
catis, segmentis mucrone conico acuminato breviusculo apiculatis ; 
seminibus solitariis, coronula brevissima contorta, fasciis 9—10. 
Swan River (Drummond, No. 7, in herb. Hook.). 
Approaches in its habit N. gelatinosa, (No. 9,) but the fertile whorls 
form somewhat larger and more spicate heads of 2—24 m. in the dia- 
meter. These little spikes are surrounded by a glossy and pellucid jelly, 
giving to the fresh plant, aecording to the observation of Drummond, 
a beautiful iridescent appearance. The seeds are somewhat less than 
those of the former, the nut of a more yellow-brown colour, .20—.30 m. 
long. 
3. N. sudbtilissima ; dioica; caule tenuissimo ; verticillis conformibus, 
remotis, minutis, densis, subgelatinosis, e foliis 7 in radiis pluribus 
duplicato-furcatis, segmentis mucrone imposito elongato anguste 
conico et acutissimo m ; seminibus solitariis oblongis, coro- 
nula brevissima, fasciis 8—9. 
Swan River, Peet No. 10. in herb. Hook. 
This species is still smaller and more delicate than N. pec 
and after the East Indian N. dyssoides, perhaps the least species of all 
the family. The seeds are more oblong than those of the preceding 
species, the nut of a dark red-brown colour, .24 m. long. It produces 
less jelly matter than the former. 
4. N. penicillata, monoica ?, dense cæspitosa ; caule tenui; verticillis
