Polystichum tsus-simense ( P . “ tcnsemense” as sometimes 
corrupted in the florist’s trade). (Plate 3, figure 3.) 
Tsusima holly fern. 
A small fern, twelve to fifteen inches high, forming 
compact clumps of several tufted crowns of leaves. The 
leaves are rather dark green, dull, twice pinnate, erect. 
With Cyrtomium , it is one of the commonest ferns 
grown as “table” ferns, for filling baskets and fern 
dishes. Native in Japanese islands. 
Dnjopteris vindescens (Plate 3, figure 4). Glossy wood 
fern. 
Offering perhaps the most beaut iful leaves of the entire 
list. The leaves develop in a circle, are three pinnate, 
one to two feet long, pale green at first, with spinulose 
segments. It is of the type of our wild D. intermedia, 
though well distinguished. Native in China. 
Dnjopteris Sieboldii (Plate 3, figure 5). Siebold’s wood 
fern. 
An odd triangular -leaved fern, with a few large broad 
pinnae. In the fertile leaves the pinnae are contracted. 
The leaves spread horizontally, and are about a foot 
long at most, dull, pale green. Native in China and 
Japan. 
Sub-tropica l varieties 
Adiantum cuneatum (Plate 5, figure?). Delta maidenhair. 
Probably more people have heard of maidenhair ferns 
than of any other single kind. Our common wild species 
is only one of over a hundred species, nearly all of which 
are tropical. Of all the species, A. cuneatum, in some 
of its varieties, is best adapted to house conditions, but 
its leaves have such a thin, delicate texture that success 
cannot be promised, although plants may be kept for 
some time. The plant illustrated is known as var. 
California. Native in South America. 
Davallia solida (Plate 3, figure 16 and plate 4, figure 2). 
Glossy davallia. 
Davallia is best known for two other Japanese species 
formerly sold commonly as “fern balls,” i.e., bundles
