8. B. penna-marina Kuhn Fil. Afr. (1868) 92.—Rhizome long, slender, 
branched, creeping, clothed with chafty en scales. Stipes 2-6 in. 
long or more, slender, red-brown, smooth and polished, sparingly scaly. 
Fronds tufted along the rhizome; sterile shorter than the fertile, 4—18 in. 
long including the stipes, }-2in. broad, often spreading or decurmbent, 
linear or linear-lanceolate, narrowed to the base, dark-green, pin ratifid 
or pinnate towards the base, texture varying from thick and coriaceous 
to almost membranous. Pinnae numerous, close-set, short, spreading, 
+-31n. long, attached by a broad base, ovate-oblong or triangular-oblong 
to linear-oblong, obtuse, entire or obscurely crenate. Fertile fronds 
erect, pinnate throughout ; pinnae numerous, rather distant, shorter and 
narrower than the sterile, linear or linear-oblong, obtuse, spreading or 
deflexed or sometimes curved upwards. Sori copious, covering the whole 
under-surface.—Lomaria alpina Spreng. Syst. Veg. iv (1827) 62; Hook.

NortH AND SoutH IJsLaANDS, CHATHAM Is~anDs, Stewart ISLAND, ANTIPODES 
IsLAND, MACQUARIE IsLAND: From the Upper Thames Valley and Rotorua southwards, 
abundant to the south of the East Cape. Sea-level to 4000 it. 
Adso abundant in temperate South America, Australia, and Tasmania. Raoul’s 
L. pumila differs from the type in the more membranous fronds and distinctly crenate 
pinnae, but is without doubt a trivial state produced by growing 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 B. penna-marina. I look upon it as a form too inconstant to keep up even as 
a variety. L. 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 fee 220). |

9. B. ‘capense Gohteell. Adumbr. (1825) 34, t. 18.—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 ft., but m dry exposed places often dwarfed to a few inches, 
while on the sides of deep wooded ravines they are occasionally 8-10 ft. 
long or even more; sterile ovate or oblong-ovate to oblong-lanceolate, 
erect. or pendulous, very coriaceous to almost membranous, bright- oreen 
to brownish-green, pinnate throughout; rhachis stout, more or less scaly, 
especially when young. Pinnae often very numerous, but in small 
specimens and in var. minor frequently reduced to 4-6 pairs, alternate, 
horizontally spreading, 3-12in. long or more, $-lin. broad, acute or 
acuminate, oblique at the base and cuneate or truncate or rounded- 
cordate or even auriculate, sessile by the midrib alone or the uppermost
