TRlCHOMANE,S—co7itinued. 
The leafy portion varies from 4in. to 12in. in length and 
2in. to 6in. in breadth; it is three times deeply cleft nearly 
to the rachis, which is very narrowly winged. The leafits 
are again cleft into deeply-toothed segments, and their 
texture, though transparent, is particularly firm. T. radicans 
is a most variable species, and some of its numerous forms 
are very beautiful. 
T. trichoideum. 
This most lovely, delicate-looking, thread-like Fern — 
admittedly the most finely-divided of all kinds shown in 
cultivation — is a native of Ecuador, Brazil, and the West 
Indies, where it grows on trunks of trees. It is of upright 
habit, with slender, creeping rhizomes, from which its

spear-shaped fronds, 4in. to Sin. long and lin. to 2in. 
broad, are produced in abundance. These fronds are borne 
on very slender, naked stalks lin. to 2in. long, and are 
three times divided nearly to the rachis, which is only very 
slightly winged at the extremity. The leafits are again 
divided into hair-like segments, which are of a membranous 
texture and have a central vein only. 
WOODSIA. 
Woodsias are small-growing', mucli-tufted, 
greenhouse and hardy Ferns, of distinct appearance 
and very neat habit. All are of soft texture and of a 
deciduous nature; their stalks are often jointed and 
separating at the joints. The genus is divided into 
Euivoodsia and PJiysematium.
