inches long, densely covered with reddish setaceous scale?, fronds

smaller than the sterile ones. Sw. Syn. Fil. p. 10. Bedd. F. S. I.

GENUS LXXXIL— STENOCHL^NA. {J. Sin.) 
{Stenos, narrow ; chloena^ cloak ; the narrow involute margin.) 
Fronds simply pinnate, the fertile contracted and very narrow, the 
sterile with the habit of Lomaria; veins simple or forked, fine and close, 
generally quite free to the margin, or rarely the two forks or even 
two separate veins anastomose; stipes adherent to the rhizome ; pinnae 
articulate with the rachis. (In palustre, the rachis or costa of the 
sterile pinnae is winged, particularly towards the apex, which wing 
has been called an obscure transverse vein, anastomosing in loops ; 
the same occurs in Pteris patens, and some Athyriums (very apparent 
in Athy. fimbriatum, var. sphoeropteroides) and it can scarcely be 
called a true vein. 
I. Stenochl^ena palustre. {Linn, under Poly podium)) Rhi- 
zome scandent, (often reaching the tops of the highest trees), fronds 
glabrous, shining, of hard texture, pinnate, 1-4 feet long, pinnas 
articulated numerous, alternate or opposite, lanceolate acuminate, 
pungently serrate towards the apex, oblique at the base, and furnished 
with a marginal gland on the upper edge, 5-10 inches long, i~i^ 
inch broad, fertile fronds very much contracted ; veins simple or 
forked, generally free to the thickened margin, rarely the forks or 
two separate veins anastomose in the middle of, or towards the 
margin of the pinnae ; rachis of sterile pinnae winged, particularly 
towards the margin, and forming a pseudo vein parallel with it
