NortH AND SoutH Isitanps, CHatHam IsLANDS, STEWART IstaAND, AUCKLAND 
AND CAMPBELL ISLANDS, ANTIPODES IsLaND, MacguaRIE ISLAND: Rather local from 
Cape Colville to the East Cape, not uncommon in hilly districts from thence to 
Wellington, abundant to the south of Cook Strait. Sea-level to 3500 ft. 
Polystichum vestitum is mainly distinguished from the widespread P. aculeatum 
by the copious dark-coloured scales, which usually clothe not only the stipes but also 
the rhachis up to its tip. It is also found in Australia, Tasmania, and Fuegia, and 
varies greatly in the size, shape, and texture of the frond, in the shape of the pinnules, 
and the extent to which they are toothed or lobed, and in many other respects. 
2. P. sylvaticum Diels in Pflanzenf. Teil i, abt. iv (1902) 192. — 
Rhizome short, erect or ascending. Stipes 4-8in. long, slender, more 
or less densely clothed with ovate-lanceolate chestnut or dark ferruginous 
scales usually mixed with linear-subulate ones. Fronds not very numerous, 
1-2 ft. long, 3-6 in. broad, lanceolate, acuminate, gradually tapering to the 
base, firm but scarcely coriaceous, 2-pinnate. Primary pinnae rather 
distant, opposite below, alternate above, lanceolate or linear-lanceolate, 
acuminate, 2-4in. long, $-?in. wide. Pinnules numerous, }-}in. long, 
ovate-lanceolate, unequal-sided at the base, pinnatifid about half-way down 
into 5-8 acute spinulose lobes. Sori usually as many as the lobes. 
Indusium not developed.—Polypodium sylvaticum Col. in Tasm. Journ. 
Nat. Ser. ii (1846) 163; Hook. f. Fl. Nov. Zel. ii (1855) 41, t. 81; Handb.

NortH anp SourH Istanps: From Coromandel and the Thames goldfields to. 
the south of Otago, but not common. 500-3500 ft. /P. A NOL Petts oe 
Although closely allied to P. vestitum this appears to me to differ in its smaller 
size and more slender habit, fewer fronds which have a much thinner texture, more 
distant pinnae, and in the invariable absence of the indusium.

3. P. Richardi J. Smith Hist. Fil. (1875) 220.—Rhizome short, thick, 
densely clothed with linear-subulate dark-brown or blackish scales. Stipes 
6-18 in. long, stout, erect, more or less clothed with rigid black subulate 
deciduous scales mixed with woolly hairs. Fronds few, tufted at the top 
of the rhizome, 9-18in. long or more without the stipes, 3-9 in. broad, 
ovate-deltoid to lanceolate-deltoid, acuminate, not narrowed at the base, 
rigid and coriaceous, glabrous above, more or less woolly or furfuraceous 
beneath, pinnate or 2-pinnate; rhachis often scaly and woolly like the 
stipes, but usually less conspicuously so. Pinnae numerous, usually close 
and compact, but sometimes a little remote, spreading, 4-4 in. long, 
¢-1} in. broad, lanceolate or ovate-lanceolate, deeply pinnatifid or again 
pinnate. Pinnules numerous, close, lanceolate or ovate-lanceolate or ovate- 
oblong, acute or mucronate or pungent, usually more or less acutely 
serrate, but sometimes the teeth are obtuse or very obseure. Sori in two 
rows In each pinnule, about half-way between the midrib and the margin.
