a farinose powder of a more or less intense bright-golden colour. — Hooker, 

 Synopsis Filicum, p. 123. Lowe, New and Rare Ferns, t. 61. 



This variety is always regarded as a difficult subject to manage ; it is, 

 however, well-deserving of any extra trouble it may cause, but will succeed 

 under the same treatment as A. w. scabrum, viz., on a dry shelf in the cold 

 house, with little water during the winter. 



A. affine — af-fi'-ne (related), Willdenow. 



This very decorative greenhouse species, commonly known as A. Cunning - 

 hamii (Cun-ning-ham'-i-i), is very distinct from the A. affine of Hooker ; it is a 

 very variable plant, both in the branching and in the size of the segments, and is 

 not likely to be mistaken for any other, as it is known only in the Northern 

 Island of New Zealand, where it is found in damp woods at a high elevation. 

 Its fronds, bipinnate (twice divided to the rachis or midrib), and measuring 

 from lOin. to 12in. long, are borne on stipes (stalks) Gin. to 9in. long and 

 furnished with long, red scales, and have one terminal pinna (leaflet), 4in. to 

 6in. long and lin. to l^in. broad, and several lateral pinnae of smaller 

 dimensions, the lowest of which are again branched. The pinnules (leafits), 

 of a sub-coriaceous (almost leathery) texture, of a dark, dull green colour above, 

 and glaucous (bluish-green) underneath, Jin. to fin. long and Jin. deep, are 

 dimidiate (fully developed on one side and scarcely at all on the other). 

 The fronds are produced in abundance from a creeping rhizome (prostrate 

 stem), covered with rough scales of a dark brown colour. The sori (groups 

 of spores) in this species are numerous and nearly round. — Hooker, Species

A. amabile — am-a'-bil-e (lovely). A garden name for A. Moorei. 



A. amcenum — am-ce'-num (pleasing). Synonymous with A. flabellulatum. 



A. andicolum — and-ic'-ol-um (native of the Andes). A garden name for 

 A. glaucophyllum. 



A. aneitense — an-ei-ten'-se (from Aneitum), Carruthers. 



This decorative species, native of the Aneitum Island, grows equally well 

 under greenhouse or stove treatment. Its fronds, ljft. to 2ft. long, and three
