Armstrong. Otago—Not uncommon on both the East and West Coasts,

Kirk. 
A well-marked plant, easily recognised by the coriaceous habit and short 
and broad rounded pinne attached by a broad base. Like L. dura, it is a 
purely littoral plant, never found beyond the influence of the sea-spray. 
8. L. alpina, Spreng. Syst. Veg. iv. 62.—Rhizome long, slender, 
branched, creeping, clothed with chaffy ferruginous scales. Stipes. 
2-6in. long or more, slender, red-brown, smooth and polished, 
sparingly scaly. Fronds tufted along the rhizome; sterile shorter 
than the fertile, 4-18in. long including the stipes, }-%in. broad, 
often spreading or decumbent, linear or linear-lanceolate, narrowed 
to the base, dark-green, pinnatifid or pinnate towards the base, 
texture varying from thick and coriaceous to almost membranous. 
Pinne numerous, close-set, short, spreading, 4—1 in. long, attached 
by a broad base, ovate-oblong or triangular-oblong to linear-oblong,. 
obtuse, entire or obscurely crenate. Fertile fronds erect, pinnate 
throughout ; pinne numerous, rather distant, shorter and narrower 
than the sterile, linear or linear-oblong, obtuse, spreading or de- 
flexed or sometimes curved upwards. Sori copious, covering the 
whole under-surface.— Hook. Fil. Hxot.t.32; Sp. Ful. i. 16; Hook.

NortH anp SoutH IsLaAnps, CHATHAM IsLANDS, STEWART ISLAND, AN- 
TIPODES IsLAND, MacquaRrig Istanp: From the Upper Thames Valley and

4000 ft. 
Also abundant in temperate South America, Australia, and Tasmania. 
Raoul’s L. pumila differs from the type in the more membranous fronds and 
distinctly crenate pinne, but is without doubt a trivial state produced by 
srowing in an unusually sheltered and shaded locality. Specimens exactly 
resembling Raoul’s plate can be found without any difficulty in both islands, 
and can generally be traced on the spot into ordinary L. alpina. I look upon 
it as a form too inconstant to keep up even as a variety. JL. parvifolia, Col., of 
which I possess a type specimen forwarded by Mr. Colenso himself, is clearly 
the same, a view which is also taken by Mr. Baker (Ann. of Bot. v. (1891) 220). 
9. L. capensis, Willd. Sp. Plant. v. 291.—Rhizome short, 
stout, often woody, erect or inclined, sometimes prostrate, clothed 
at the top with large chestnut- brown scales. Stipes stout, long 
or short, usually densely scaly at the base. Fronds numerous, very 
variable in size, usually from 1-4{t., but in dry exposed places.
