Porrs.— Notes on Ferns. 961 
judged to be a variety of L. procera. A plant the writer has under cultiva- 
tion has nine fronds (barren and fertile) exhibiting the peculiar habit from 
which it was named. 
L. patersoni, Spreng. 
Near springs or rills in gullies and outskirts of bush on' Banks Penin- 
sula; in similar positions in the Malvern Hills it may be found growing in 
the greatest luxuriance, fronds giving a measurement of above 8 feet in 
length. 
Asplenium trichomanes, Linn. 
In crevices of rocks in the gorge of the Ashburton river, on the lower 
spurs of Mount Herbert. 
A. flabellifolium, Cavan. 
The finest form of this elegant fern that has fallen under the writer's 
notice was obtained amongst sheltering rocks in the dry bays of Lake 
Ellesmere. 
A. faleatum, Lam. 
Fine specimens on Podocarpus spicata, near Akaroa. 
Aspidium aculeatum, Swartz. 
Often found growing as a parasite, most frequently on aged specimens 
of Griselinia littoralis (broadleaf) in the bush, lying high on Banks 
Peninsula, 
Gymnogramma leptophylla, Desv. 
Abundant about the rocks in Port Cooper up to the head of the harbour. 
This delicate fern can be cultivated with little trouble ; it is produced freely 
wherever the seed has been permitted to ripen ; in crevices amongst moist 
rocks or stones it soon becomes established. 
Gymnogramme alpina, sp. nov. 
Rhizome dark brown, stout, ascending, clothed with brown scales. 
Fronds silvery-green above, oblong, narrow, 1-8 inches long, half inch 
broad; pinnate, densely villous, soft, thick in substance. Stipe silvery- 
green or brownish, tufted, stout or slender, densely villous.  Pinns 
petioled, except the last three, in pairs or alternate, deltoid or cuneate, with 
two or three blunt irregular-shaped lobes, both sides densely villous, veins 
flabellate ; sori ovate, numerous, covering a large portion of the under- 
surface of pinne. : 
A hardy perennial, growing in crevices of rocks on steep facings of the 
 Bouthern Alps at an elevation of some 8,000 feet. In this habitat it with- 
stands the rigours of winter, the severity of which is quite unknown to the 
dwellers near the coast. Itis probably the most densely villous of all the New 
Zealand Filices ; in its soft woolly texture and silvery-grey colours it bears 
close resemblance to several plants of our alpine flora. Compared with G.
