being cut into slender, linear segments, some of whicli 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 

 Catalogue of Filmy Ferns, 1871, p. 17. 



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 Sin. 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. tiichophyllum. 



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 Sin. long, Jin. to fin. broad, varying in shape from 

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

T. (Feea) nanum — Fe'-e-a ; na-num (dwarf). A synonym of T. botryoides. 



T. Obscurum — ob-scu'-rum (obscure). Synonymous with T. rigidum. 



T. oliYaceum — ol-i-va'-ce-um (olive-green). A variety of T. pyxidiferwm. 



T. parvulum— par'-A'ul-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
