A. (Euaspidium) repandum— Eu-as-pid'-i-um ; rep-an'-dura (wavy- 

 leaved), Willdenow. 

 A strong-growing, stove species, native of the Philippine Islands. The 

 fronds are 2ft. or more long and 1ft. to ljffc. broad, and are borne on stipes 

 (stalks) 1ft. to 2ft. long ; they are deeply pinnatifid (cut down nearly to 

 the midrib) at their summit and show slightly sinuated (wavy) lobes ; below 

 this there are four to eight pinnae (leaflets) on each side, and these are Gin. 

 to Sin. long and about ljin. broad, terminating in a tapering point and 

 narrowed below, with their edge bluntly waved. The sori (spore masses) are 

 disposed in two distinct rows near the main vein. — Hooker, Synopsis Filicum, 

 p. 259. Nicholson, Dictionary of Gardening, i., p. 127. 



A. (Polystichum) rhizophyllum — Pol-ys'-tich-uni ; rhi-zoph-yP-lum 

 (frond-rooting), Swartz. 

 A very small-growing species, native of Jamaica and Cuba. Its little 

 fronds, 2in. to Gin. long and fin. broad, and borne on slender, tufted stalks 

 lin. to 2in. long, have their narrow upper half lengthened out and usually 

 rooting at the extremity ; their lower half is cut clown to the flattened 

 rachis (stalk of the leafy portion) into nearly entire lobes of a somewhat 

 leathery texture. The sori (spore masses) are scattered over the whole 

 under-surface of the fertile leaflets. — Hooker, Species Filicum, iv., p. 7.

A. (Polystichum) Richardi — Pol-ys'-tich-uni ; Rich-ard'-i (Richard's), 

 Hooker. 



A greenhouse species, native of New Zealand, of medium dimensions and 

 differing from A. aculeatum by its more rigid texture and shorter teeth, 

 and by its lower pinna? (leaflets) being of the same size as those of the 

 centre of the frond. Its fronds are of a coriaceous (leathery) texture, 9in. 

 to 18in. long and Gin. to 9in. broad, and are borne on stout, erect stalks 

 Gin. to 12in. long and scaly throughout. The sori (spore masses) are 

 disposed in two rows midway between the midrib and the edge. — Hooker, 

 Species Filicum, iv., p. 23, t. 222. 



A. rotundatum — rot-un-da'-tum (rounded). A variety of A. angular e.
