Bornéo (Teysmann, Nos. 8577, 8590; Teuscher).— Differs from 

 Drynaria cornucopia (Thayeria cornucopia, Gopel. 7 Philipp. Journ. 

 Sci., I, Suppl., 165, tab. XXVIII) in having the cup-leaves much 

 smaller, not solitary on short latéral branches of the rhizome, 

 not cornet-shaped, but quite enclosing distant portions of the rhizome 

 itself, and agreeing with said species in having the cup-leaves 

 involute with imbricated side edges so as to form a perfect, humus- 

 collecting organ, with the rhizome rooting into the humus.
