2-4 lines long, 1^-3 lines deep, opposite and sometimes alternate, petiolate, 

 obliquely-flabelliforin, sub-rliomboidal, 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. G. 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 pinnae, 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 pinnae 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, pinnae numerous, rather 

 distant, sub-opposite, adnate and decurrent, coarsely and prominently 

 veined, membranaceous and puckered, deeply and coarsely crenate- serrate,
