 sibly Mettenius's P. repandulum from Ceylon (" Gardner, n. r)9''). The num- 

 bers received by iMettcnius of Gardner's Ferns are invariably different from mine. 

 The present is the only species of the Cryptosorus group I have from Ceylon. 



69. P. (Eupolypodium) Celebicnm, Bl. ; "fronds nutant 

 (sul)falcatc) long stipitate (3-5 inches) lanceolate dee[)ly pin- 

 natifid coriaceous, segments horizontal alternate linear obtuse 

 ciHated veinless beneath, lower ones abbreviated subtriangu-

Ilab. On trees in woody mountains of Celel)es Klol)at, Reinvardt, in Illume. 

 Borneo, //. Low. — This is the largest and most coriaceous of the CryplosnruH- 

 group, readily recognized by its villous stipes and racbis, and immersed and con- 

 sequently (externally) indistinct venation. My specimens from Horneo well cor- 

 respond with Blume's description and figure, particularly the latter. Sori nume- 

 rous on each segment or pinna (for this s])ecies is rather pinnate than piimatifid), 

 distinct (not confluent), 12-16 on each side the costule. 



70. P. (Eupolypodium) Khasyanum, Hook. ; caudex short 

 creeping scaly, stipites short tufted (articulated upon the 

 caudex as appear to be all of this group), fronds a span to 

 14 inches long 1-1 i inch broad subcoriaceo-membranaceous 

 hairy below and on tiie costa deeply nearly to therachis pin- 

 natifid with very acute sinuses, segments apj)r(>ximate liori- 

 zontally ])atent from a broad and subdecurrent base oblong 

 obtuse or the lower ones subtriangular or short and rounded 

 entire or subsinuate ciliated, costule flexuose, and simple 

 oblique veins apparent, sori short-oval eight or ten on each 

 segment in two rows nearer the margin than the costa sunk 

 into an oval cavity (having an elevation on the opposite or 

 upper side) bordered by a raised margin. — Hook. Ic. Plant, t, 

 949 {or Century of Ferns, t. 49). Metten. Polyp, p. 50.
