A CROSTICHUM.

A. (Elaphoglossum) dimorphum — El-aph-og-los'-sum ; dim-orph'-um 

 (of two forms), Hooker. 

 This greenhouse species from St. Helena is of botanical interest on account 

 of its being given in the " Synopsis Filicum "as " the only Elaphoglossum 

 having the fronds distinctly incised or crenated." This applies only to the 

 barren fronds, of a leathery texture and about 4in. long, as the smaller fertile 

 ones are nearly entire (uncut). — Hooker, Synopsis Filicum, p. 406. 



A. discolor — dis'-col-or (of two colours), Kuhn. 



An Amazon, stove, botanical species, with spear-shaped fronds about 4in. 

 long, densely scaly beneath. — Hooker, Synopsis Filicum, p. 521. 



A. (Photinopteris) drynarioides — Pho-ti-nop'-ter-is ; dryn-a'-ri-o-i'-des 

 (Drynaria-like), Hooker. 

 This stove species, from Penang 

 and the Solomon Islands, is very 

 peculiar on account of its fronds, 

 several feet long and lft. or more 

 broad, being sessile (stalkless) ; it 

 also differs from most other known 

 kinds in the upper part of the fronds 

 being furnished with Lomaria-like 

 pinnse (leaflets) quite lft. long, and 

 which, although adnate (attached 

 throughout their length) to the 

 rachis (stalk), break away from it 

 readily. See Fig. 26. — Hooker, Species 

 Filicum, v., p. 282. Beddome, Ferns 

 of British India, ii., t. 325.

A. Feei — Fe'-e-i (Fee's), Bory. 



A West Indian stove species, 

 of purely botanical interest, with 



leathery fronds which, including the stalks on which they are borne, seldom 

 exceed 3in. in length. — Hooker, Synopsis Filicum, p. 404.
