T, Kmx.—On Plants collected at Okarito, 443 
receptacle terminating the rachis, and by its pale green colour, In the 
North Island it appears to be confined to the vicinity of Cook Strait. 
Hymenophyllum cheesemanni, Baker, 
Mr. Hamilton is the first discoverer of this plant in the South Island. 
Recently it has been collected near Hokitika by Mr. Tipler. 
Hymenophyllum armstrongii, Kirk. 
This shows a considerable extension of its southern range. Mr. Hamil- 
ton’s specimens suggest the great probability of the identity of this and the 
preceding species, as many fronds are entirely destitute of the stout marginal 
nerve which forms the only prominent distinction between the two, The 
same rhizome sometimes exhibits fronds with the marginal nerve, arrested 
at different stages of development, from the typical condition of H. arm- 
strongit, in which the marginal nerve is fully developed, to that of H. cheese- 
manni, in which it is entirely wanting. The marginal nerve may even be 
developed on one side of a segment, as in H. armstrongii, while the other | 
side exhibits no trace of it, as in H. cheesemanni, Not unfrequently it is 
reduced to a slight thiekening at the base of each tooth. At present I am 
unable to satisfy myself whether its absence must be considered due to 
simple non-development or to absorption. 
Hymenophyllum villosum, Colenso. 
This habitat is at a lower altitude than is usually affected by the species, 
although I am not certain that it is the lowest yet observed. 
Hymenophyllum pulcherrimum, Col. 
Mr. Hamilton's specimens are the finest I have seen, some of them 
being twenty-seven inches long, but remarkably narrow in proportion. 
Hymenophylium rufescens, n.s. 
At present only known from this locality and from another in the North 
Island. See Art. LXXIV. 
Davallia nove-zealandig, Col. 
The fronds of this plant also are of unusual luxuriance, a solitary pair 
of pinne in the collection, measuring nineteen inches from tip to tip. 
Lomaria, sp. 
Two fragments of a plant which may be Lomaria attenuata, Willd., are 
comprised in the collection. They are about four or five inches in length; 
one specimen is the acute apex of a barren frond, the lowest segments of 
Which are apparently pinnate, with an aeute narrow sinus, and attached 
by very broad bases; segments acute, margins uneven. The other speci- 
men is the basal portion of a fertile frond, pinnules sessile, 14 inch long, 
With broad bases, acuminate, the two lowest deflexed. The specimens are 
too imperfect to admit of positive identification, but the plant certainly differs 
from all deseribed New Zealand forms.
