POL.YPODl\JM—conti?med, 
nearly all pinnatifid, being composed of narrow-spear-shaped 
leaflets of a leathery texture^ deep green in colour and 
naked on both sides. The large, round sori lare disposed m 
single rows close to the midvein, and are so distinctly im- 
mersed in the frond as to form protuberances on the upper 
side. This species is a particularly shallow-rooting plant; 
it flourishes best in a floww-pan, in a mixture in which 
fibrous peat predominates. 
P, Catharinse. 
An easily-cultivated, evergreen, stove species, a native 
of Brazil. Its simply-pinnate fronds. Gin. to 12in. long and 
Sin. to 5in. broad, are produced from a wide-creeping 
rhizome clothed with dark brown, spreading scales, and 
borne on erect, naked stalks 4in. to Gin. long and of a 
glossy nature. The texture of their leafletis, which are 
l^in. to 3in. long and Jin. to ^in. broad, is somewhat 
leathery, and their colour is dark, dull green. The large, 
round sori are disposed in single rows close to the midrib. 
P. Catherince of gardens is synonymous with P. loriceum 
latipes. 
P. chnoodes. 
For growing in hanging baskets, this West Indian and 
Venezuelan stove species, of drooping habit, is very useful. 
Its elegant fronds, 1ft. to 2ft. long and 4in to Din. broad, 
are cut down to the rachis, into distinct, sickle-shaped, 
opposite leaflets 2in. to 4in. long, ^in. to fin. broad, heart- 
shaped at the base, of a soft, papery texture, light green 
in colour, and finely hairy on both surfaces. They are pro- 
duced from a stout rhizome densely clothed with soft, 
spreading scales of a dull brown colour, and borne on erect, 
slender, naked stalks 4in. to Gin. long. The spore masses 
are disposed in two series on each side of the main veins. 
This species was once known as P. dissimile, 
P. conjugatum. 
From Queensland comes this handsome species, which 
has long pinnately-divided, shining, lance-shaped fronds, 
springing from a stout creeping rhizome. The leaflets are 
alternate and lanceolate, with wavy margins. The sori, 
which are borne in two rows, between each of the primary 
veins extend from the midrib to the margin. A favourite 
exhibition plant. 
P. coronans. 
Synonymous with P. lieracleum. 
P. cuspidatum. 
Synonymous with P. per sicoe folium.
