154 15. OLEANSRA. 



Rhizome horizontally creeping, clothed with + adpressed, subulate, ciliate 

 scales. Stipes close or scattered, 2'/i — 20 c.M long, articulate within 1 — 7c.M. 

 from the base. Fronds 20 — 45 c.M. long, narrowed gradually towards both 

 ends. Texture herbaceous or membranaceous; midrib and both surfaces slight- 

 ly hairy. Sori in regular rows very near the midrib; indusium firm, oblique. 



Vai*. Sibbaldii: Textm-e thinner; surfaces more hairy; sori in very 

 irregular, wavy lines, rather distant from the niidrib.

Rhizome wide-creeping, densely clothed with yellow, spreading, subulate 

 scales. Stipes naked, brown, articulate about the middle. Fronds to + 30 

 c.M. long, 4 — S C.M. broad, narrowed gradually towards the base, the apex 

 finely acuminate. Texture thin, the edge thickened, finely ciliate; upper sur- 

 face pubescent especially on the midrib; under side of the midrib regulai'ly 

 clothed with 2 opposite rows of spreading, yellow, subulate scales. Sori 

 close, placed in 1 wavy row on each side near the midrib, sometimes in 2 

 close, irregular rows; indusium pale-yellowish, often subpellate.

Sori roundish, terminal on the anterior veinlets of the once forked veins. 

 Indusium roundish-reniform, fixed by the sinus. 



Rhizome creeping* or scandent. Stipes articulate to the rhizome. Fronds 

 pinnate; piimae articulate to the rachis. • 



A small genus, very near Nephrolepis, distinguished from •% i by the 

 articulated stipes.
