an underground, creeping rhizome (stem), are of two kinds. The barren 

 ones, 2in. to Sin. each way, heart-shaped, bluntish at the point, and with 

 rounded basal lobes and a deep notch between them, are borne on dark 

 chestnut-brown, glossy stalks Sin. to 4in. long. The fertile fronds have their 

 lobes much sharper, the whole 

 leafy portion being nearly 

 triangular ; these are borne 

 on stalks similar to those of 

 the barren fronds, but often 

 1ft. long. Both kinds are of 

 a somewhat leathery texture, 

 smooth and dark green on 

 the upper surface, whereas 

 their under -side, which is 

 slightly hairy and of a paler 

 colour, is completely covered 

 with sori (spore masses) that 

 are narrow at first but even- 

 tually become confluent. The 

 barren fronds are proliferous 

 at their base, where one or 

 several little bulbils are pro- 

 duced, and by means of these 

 this species can easily be 

 propagated. — Hooker^ Species
