THE DICTIONARY OF GARDENING, 
Trichomanes—continued. 
membranous and pellucid, smooth or bearing simple, 
forked, or stellate hairs. Sori marginal, always ter- 
minating a vein, more or less sunk in the frond; involucre 
monophyllous, tubular, closely corresponding with the. 
frond in texture, the mouth truncate or winged, or slightly 
two-lipped; receptacle filiform, elongated, often consider- 
ably exserted beyond the mouth of the involucre, capsuli- 
ferous principally at the base; capsules sessile, depressed, 
- surrounded by an entire, broad, nearly transverse ring, 
bursting vertically. The introduced species are here de- 
scribed; except where otherwise stated, they need stove 
heat. They should be “grown in square, shallow pans 
and boxes, well-drained in the ordinary way, and having 
about 2in. of peat soil mixed with nearly half its bulk 
of sand and small broken potsherds; but soft sandstone 
is best. For the creeping sorts, the soil should be raised 
in the form of a mound; and for those that have long- 
extending rhizomes, if soft stone cannot be had, it is 
desirable to invert a pan or common deep pot, covering 
it with a layer of soil, as already explained, to which 
the plant will cling, and soon form a green hillock. 
Junks of wood answer the purpose, but in a moist, close, 
and warm atmosphere, Fungi and insects breed, and in 
a short time the wood decays, causing unnecessary dis- 
turbance of the whole mass of the plant” (J. Smith).
