Very distinct in Sr Berraee. thin, pellucid leaves with Bryoid areo-

This and the following differ from the remaining species of the section 
in the areolation, which is angular, more or less hexagonal or hexagono- 
andor. thin-walled, and rather pellucid, the basal cells, especially of the 
vaginant lamina, being very lax, elongate, and hexagonal-rectangular. 
F. oe has the leaves long and narrow, with a ve ery acute acumen, 
the tip often a cuspidate point formed by the confluent nerve and border. 
The border and nerve may, however, as pointed out by Beckett, sometimes 
vanish below the apex in the upper leaves. The bending of the nerve where 
it leaves the vaginant lamina (from which the specific hame) is usually a 
marked ¢ ae ut may be indistinct, especially in leaves . Vieied 
stems. e rescence may perhaps be truly dioicous; I have not seen 
male ki nts, nor were they found by Beckett. The ¢ apsule may 8 erect 
or more or less inclined ; capsules gathered before maturity generally become 
strongly arcuate. 
It appears to be a frequent species in New Zealand, and probably occurs 
‘in Tasmania and Australia.
