 (Blume's), Hooker. 



This greenhouse species, named also by Blume Leptochilus lomarioides 

 (Lep-toch-i'-lus lo-ma-ri-o-i'-des), is a native of Assam, Java, Samoa, and the 

 Philippine Islands, where it is found growing on trees, of the bark of which its 

 thick, wide-climbing rhizomes (long prostrate stems), of a woody nature, readily 

 take possession. Its barren fronds, which measure from 2ft. to 3ft. in length 

 and about 1ft. in breadth, are borne on scaly stipes (stalks) not more than 

 6m. long, and are furnished on each side with numerous pinnce (leaflets) 

 of a membranous or soft texture ; these are sessile, or without a stalk, and 

 from 4in. to 6in. long, with their extremity acuminate (tapering to a point) ; 

 they have their edge slightly toothed, and their base rounded. The fertile 

 fronds are equally pinnate (divided to the midrib) ; but the pinnse, 4in. to Bin. 

 broad, are less closely set, and never more than Jin. broad. — Hooker, Sjjecies 

 Filicum, v., p. 268. Nicholson, Dictionary of Gardening, L, p. 19. 



A. Boryanum — Bo-ry-a'-num (Bory's), Fee. 



A West Indian, stove species of botanical interest, with barren fronds 

 often 1ft. long and 3in. broad, and fertile ones much smaller, but borne on 

 longer stalks. — Hooker, Synopsis Filicum, p. 407. 



A. Burchellii — Bur-cher-li-i (Burchell's), Baker. 



In this Brazilian, greenhouse species, of little decorative value, the barren 

 fronds, of leathery texture, often attain 2ft. in length and lin. in breadth, 

 while the fertile ones are of much smaller dimensions. — Hooker, Synopsis 

 Filicum, p. 401. 



A. (Polybotrya) canaliculatum — Pol-yb-ot'-ry-a ; can-a-lic-ul-a'-tum 

 (channelled), Hooker. 

 This gigantic species, native of Venezuela, which succeeds equally well 

 under either stove or greenhouse treatment, is of a particularly well-developed, 

 scandent (climbing) habit, and well adapted for running up a Tree Fern 

 stem, or for covering the stump of a dead tree. Its barren fronds, which are 

 produced from a wide-climbing rhizome (long prostrate stem) of a woody nature, 

 covered with spines or short scales, are of a dark glossy green colour, and of
