being cut into slender, linear segments, some of which, standing forward, as 

 in the well-known Todea superba, give the whole plant an effect of almost 

 incomparable softness and richness. It is a native of the mountains of Java, 

 where it occurs at elevations varying between 4000ft. and 7000ft. — Backhouse s

T. membranaceum — mem-bra-na'-ce- um (membranous), Linnceus. 



This species, native of Tropical America, is of most singular appearance. 

 Its nearly stalkless fronds, of a thin and transparent nature and nearly round, 

 are 2in. to 3in. broad and more or less deeply cut from the circumference 

 towards the centre, with rounded lobes conspicuously scaled on their margins 

 — a character unique in the genus. This plant succeeds best on porous stone. —

T. Morierii — Mor-ier'-i-i (Morier's). Synonymous with T. trichophyllum. 



T. muscoides — mus-co-i'-des (moss-like), Swartz. 



This species, native of Tropical America, Asia, Polynesia, and Africa, 

 is also known as T. erosum,. It produces from a slender rhizome shortly- 

 stalked fronds lin. to 3in. long, £in. to jin. broad, varying in shape from 

 linear-oblong to spoon-shaped, nearly entire or bluntly lobed, especially above.

T. parvulum — par'-vul-um (rather small), Poiret. 



This small-growing species, native of Japan, China, Java, Madagascar, &c, 

 is a remarkably pretty plant, of easy culture either on a fragment of 

 Tree Fern or on a piece of fibrous peat. Its very attractive little fronds, 

 produced from wide-creeping, thread-like, interlaced rhizomes, and borne on 

 very short, slender stalks, are round or nearly so in general outline, wedge- 

 shaped at the base about Jin. each way, and cut like a fan about half-way 

 down from the outer edge in the direction of the base into narrow, irregular
