CoLENSo. — On some Neiv Ferns, 419 



Hah. Hilly woods south-west of Dannevirke ; 1896 : W. C. 



Obs. I. A species having affinity with A. {Polysticlmm) 

 richardi, Hook., but diifering iu several characters, as in 

 larger size and form and different colour, in being bipinnate 

 with pinnae and pinnules distant larger and much more acu- 

 minate, in shape and size of pinnules largely and sharply 

 serrated, particularly basal pair on pinnae which are sub- 

 pinnatifid, in its slender pale stipe and rachis, in it not being 

 mealy or subfurfuraceous below, and also wanting those 

 curious ciliated scales beneath on segments. 



II. Sir W. J. Hooker says of A. (P.) richardi, " Fronds 

 oblong-ovate, suddenly and finely acuminate, subfurfur- 

 aceous beneath with minute subulate scales ciliated at their 

 broad bases ; pinnate (scarcely sub-bipinnate), pmnaB 2in.-3in. 

 long, close and compact, deeply pinnatifid nearly to the costa ; 

 segments laiiceolate, numerous, close-placed, margin entire or 

 obsoletely crenate rather than serrate" (" Sp. Filicum," vol. 

 iv., p. 23). His figure with dissections of the same fern, pi. 222, 

 I.e., are very good. Baker also, in subsequently describing it, 

 adds, "Differs from A. aculcatum by its more rigid texture, 

 shorter teeth, and lower pinnae not reduced" (" Syn. 

 Filicum," p. 253). Sir J. D. Hooker also, in his coloured 

 drawing of A. richardi (tab. 78, "Flora of New Zealand ") — 

 although the pinnae of his figure are more distant than those 

 of that one in "Sp. Filicum" {su'pra), and the drawing in 

 "Sp. Filicum " was made after that in the "Flora of New 

 Zealand," and more particularly to represent A. richardi — 

 nevertheless the pinnules are also sessile, crowded, and scarcely 

 serrate — just as Sir William has them ; all which, as we w-ell 

 know, truly represents our New Zealand fern A. (P.) richardi 

 {vera) ; of which species there are also several sub-varieties, in 

 size all more or less closely resembling the type. 



Todea, Willdenow. 

 1. T. mcirginata, sp. nov. 



Plant suberect, tufted, sometimes with short caudex com- 

 posed of coalescent stipites. Stipe 5in.-7in. long (or more), 

 stout, deeply sulcated above, dull dark-green, thickly covered 

 with red-brown matted floccose hairs (also the same, but more 

 slightly on rachis and subrachises below). Frond oblong- 

 lanceolate, 2ft. 5in. long, 9in.-10in. broad at middle, tip 

 ^cute, base truncate (Sin. wide) ; lower rachis stout as stipe 

 but very slender above, bipinnate, glabrous, dark - green, 

 stoutish - membranaceous. Pinnae numerous, sub-30-jugate, 

 oblong (or subdeltoid), acuminate, broadest at base, 4iin.- 

 5in. long, l^in. wide, pinnate, subfalcate, subopposite above, 

 opposite below, somewhat distant, 2in. apart below, decreasing 

 in size from middle downwards. Pinnules oblong, 6-7 lines
