* (4) M. Diifii, Moofe, Nich., Diet. d'Hort., Ill, 461, fig. 632. 



Stipes tufted, erect, chaffy like the rachis, 10—20 c.M. long. Fronds 

 + 25— 3b c.M. long, linear, 1—1 '/j c.M. broad, narrowed gradually towards 

 the base, the apex once or more times forked. Pinnae numerous, the lower 

 ones reduced, distant, the central ones approximate, each consisting of 2 oblong 

 or flabellato-orbicular, strongly imbricated leaflets, which 'are joined at the 

 very base, with the edges entire or irregularly crenate to slightly lobed. 

 Texture herbaceous; under surface clothed with few, scattered, minute, chaffy 

 scales; veins of each leaflet flabellate in the orbicular, pinnate in the oblong 

 forms.

Caudex short, stoloniferous, densely clothed with black-brown, lanceolate 

 scales. Stipes tufted, + 30 c.M. long, ± scaly at the base. Fronds ± 

 60—100 c.M. long, ± 20 — 3S c.M. broad, hardly narrowed towards the base, 

 sterile in the lower part. Barren pinnae narrow-lanceolate, 1^-3 c.M. broad, 

 the base slightly unequal, the edge crenate, the point acute; fertile pinnae 

 mostly narrower, the highest ones often very narrow, linear, the base + 

 cuneate, the edge more or less deeply lobed sometimes nearly to the costa, 

 the sinuses + rounded, the lobes blunt. Texture coriaceous; rachis ± fur- 

 furaceous; surfaces + naked; veins forked at the base, the barren branch the 

 shortest, often very short. Sori ferminal on the lobes, 1 to each lobe.
