This species is unknown to me. — C. J. Brooks' No. 41 3/S from Leôo//^'^ 

 Tandai (Sumatra, Benkoelen), which may be a more developed form of this, 

 is distinguished from Rosenstock's diagnosis tn having the pinnae more 

 numerous, 5—7 on a side, coriaceous, narrower, bluntly and shallowly 

 serrulate-crenate, subentire at the acutely long-acuminate, subcaudate apex, 

 obiiquely rotundate-cuneate at the base, broadest at the upper base, sub- 

 glabrous (glabrescent?), as are the stipe and rachis, the higher veins not 

 simple, the higher sori' asplenioid, the others phyllitoid. It resembles 

 siiperficially seen Asplenium macrophyllum Sw.

 natae; pinnae centrales maximae, minus approximatae, sessiles, usque ad 

 7'/o — 10 cm. longae et ^/4— l'/2 cm, latae ; pinnae inferiores paullo remotae, 

 subpeliolulatae; venae subhorizontnles, simplices vel hic illic furcatae.
