LESKEACEAE, 303 
A very ae ag state occurs in the extreme north of the 
Island, especially on Gt. Barrier Id., apparently in very shady, damp 
habitats, with lar a lax, ae green foliation, the ramuline leave 
very little smaller Pie the rest, large, See very little concave, 
and often with a tendency to a complanate, bifarious arrangem ment 
similar to that of some tropical species, e.g., the African Ee peeves 
Mitt. The leaves cur are irregularly crisped when dry t had 
not been for the prese in one case, of intermediate Eat ae 
ing it with T. Goren < should not have thought of placing it here. 
A less strongly marked state of the same thing was sent me from 
the New York Bot. Garden as “ H. (Tamariscella) ee tee 
pinnatum C.M. in sched., Greymouth, N. Hel me 
form was also collected at Dunedin by Berggren (No. 2558). 
Subgenus B. Ev-THurpium Lindb. 
Mostly robust, rigid plants. Dioicous. Stems frequently arched, 
rooting at the tip, and with stoloniferous prolongations, so as to be 
interruptedly frondose; irregularly bi- or tri-pinnate. Paraphyllia 
usually high, more or less foliose. Branch leaves not ineurved- 
eatenulate when dry; cells unipapillose. Seta more or less thick.

Quite distinet a the preceding species in the habit of growth, 
the interrupted branching, the densely pinnate ramuli (in all the 
previous plants the ramuli are sparse, except in J furosum var 
fulvastrum, which is quite different); and in the character of the 
des organs it These are more or less closely imbricate h 
b 
shouelt net from the incurving of the dry leaves. They a e very 
and slightly eristate at back, often terminating abruptly in a spicule. 
The ae is long and stout; the capsule large.

This must remai n a doubtful species. Only two or three stems 
oceur in Mitten’s herbarium, of which Mrs. Britton has kindly sent 
me a part. So far as can be judged from this it is a plant similar
