 LVI, 351. 



Main racliis often finely (deciduously ?) puberulous above; pinnae 

 crenate, toothed or sliglitly lobed, acute to acuminate, the lowest not 

 rarely oblique at the base and cut to '/i-way down to the costa into 

 blunt, entire, crenated or slightly toothed lobes; texture varying from 

 thin-herbaceous to firm-papyraceous; veins about 3 — 5 on a side ; sori about 

 3— 5 on each side of the main veins or costulae. 



Var. latipinEiatuni: Lateral pinnae proportionally short and 

 broad, to 12 '/j cm. long by 4 cm. broad, the apex acuminate, serrate, the 

 margin broadly serrate-crenate, crenate-lobate, somewhat lobed towards 

 the base, the lobules subentire or repando-crenulate. — ■ Sumatra.
