It is worthy of remark that Tupeia antarctica is found parasitic on a 
greater variety of trees and shrubs than any other New Zealand Loranth. 
Loranthus flavidus, on the other hand, appears to be restricted to Fagus 
solandri. 
Arr. XLI.—Description of a new species of Hymenophyllum. 
By T. F. Cuarzseman, F.L.S. 
{Read before the Auckland Institute, 11th October, 1875.] 
In my account of the Botany of the Titirangi District, published in the 
fifth volume of the ‘“ Transactions,’ I have briefly alluded to a Hymeno- 
phyllum, as being distinct from any previously described form. Since then 
I have gathered the same plant in several widely separated localities, in 
- some of which it is by no means uncommon; and there can be little doubt 
that it will ultimately be found to be generally distributed throughout the 
colony. My view of its specific distinctness has been confirmed by Mr. 
Baker, and a full description is given by him in the new edition of the 
“Synopsis Filicum ;’’ but as this work is not generally accessible here, I 
have drawn up the following brief diagnosis, including a few points of 
difference not mentioned in the ** Synopsis.” 
Hymenophyllum cheesemant, Baker. 
Minute, forming tufts or cushions on the branches of trees, or creeping 
among Mosses and Hepatice. Rhizome branched, wide-creeping, smooth 
and wiry. Stipes, 2-3 lines long, filiform. Fronds one-sixth to three- 
fourths of an inch long, simple, forked, or irregularly digitately divided ; 
quite glabrous; texture, firm; segments, about one line broad, linear oblong 
or ligulate, obtuse, with only a single central costa in each; margins not 
thickened, strongly ciliate-toothed. Sori, one to three to a frond, terminal- 
on the segments; involucre nearly free, orbicular, of a much thicker and 
more compact substance than the frond, divided almost to the base; 
valves convex, quite entire ; receptacle generally included. 
Habitat.—Thames Goldfields, Whangarei, Hunua and Titirangi, Great 
Barrier Island. Not seen below 500 feet. I am indebted to Mr. Kirk for 
my knowledge of the Great Barrier locality. 
Apparently a very distinct species. Its nearest ally in New Zealand is 
undoubtedly H. minimum, which I am glad to find Mr. Baker now considers 
to be distinct from H. tunbridgense. From both these plants it can readily 
be distinguished by its peculiar habit, less divided, often quite simple fronds, 
and by the position and form of the involucre. The Australian H. pumilum,
