2-4 lines long, 11-3 lines deep, opposite and sometimes alternate, petiolate, 
obliquely-flabelliform, sub-rhomboidal, and broadly cuneate, spreading, 
distant, lower very remote, upper approximate; petioles slender; the larger 
pinnules of the barren fronds and frequently of the fertile ones deeply 2-4 
(mostly 3-) lobed on upper convex margin; lobes laciniate and irregularly 
crenate and toothed, the lower and inner margins of pinnules entire; veins 
radiate, free, forked, clavate at apices, prominent, dark-coloured, not ex- 
tending to margin. Involucres, the inner valve green, broad, extending 
quite to margin of the outer one; margins of both closely and deeply laci- 
niate-toothed ; teeth sub-rigid, very obtuse; margins (with petioles and 
upper rhachis) bright red, and revolute when young. Sori, straw-coloured, 
but reddish with age. 
Hab. In hollows on high land, tops of hills near the north head 
of Wellington Harbour (but not plentiful), 1846-7: W.C. Whanga- 
parapara, west coast Great Barrier Islet, Thames, 1883: Mr. C. P. 
Winkelmann. 
Obs.—A species having affinity with L. linearis, Sw., and probably with 
L. incisa, Prentice, another Australian species (judging from Bentham’s 
description of this latter, as I have not seen any specimens of this plant), 
and with L. lobbiana, Hook. (also from his description). Differing, how- 
ever, from L. linearis (a species found plentifully in New Zealand—Bay of 
Islands, and elsewhere) in size—in its larger and lobed pinne, which are 
also on slender petioles—in form and colour of stipes and rhachis, and in 
the stout obtuse toothing of its involucres. Here I might very well adopt 
Sir W. J. Hooker’s remark in describing the fern above mentioned, L. 
lobbiana :—'* Without a figure I should despair of making its character 
intelligible, so difficult is it to define in words the forms of the pinne of 
these plants.” —Sp. Filicum. 
Genus 16. Lomaria, Willdenow. 
Lomaria oligoneuron, sp. nov. 
Plant under a foot high, tufted, 6-12 fronds to a plant, glabrous, sub- 
erect and spreading, with a short, stout, woody caudex about 1 inch long. 
Roots stoutish, long, spreading, densely clothed with light brown, shining, 
shaggy hairs ; stipes short, usually under 1 inch (sometimes of sterile fronds 
extending to 2 inches or more, and of fertile fronds still longer), slender, 
dark purple-brown, slightly roughish below, sub-cylindrical, channelled 
(with rhachis) on the upper surface; scales long at base and for some 
distance upwards; fronds pinnate ; sterile ones sub-lanceolate, broadest near 
tips, flat, 7-9 inches long, 10-14 lines broad, pinne numerous, rather 
distant, sub-opposite, adnate and decurrent, coarsely and prominently 
veined, membranaceous and puckered, deeply and coarsely crenate-serrate,
