Teysmann'sNo 13737 from Celebes (Bontliain, Boeaka n g) is the 

 only spécimen occurring in the Buitenzorg Herbarium, referrible to this species 

 and recognizable in having the primary branches gemmiferous below the 

 apex. In ali other respects it resembles too much Pt. longipes DON, 

 to which species my var. javanica (Bull. Btz, VII (1912), 27) should be 

 referred, 



Pteris Wallichiana AOARDH. Rec. Spec, 69; V.A.V.R., Mal. Ferns, 372. 



The typical form of this species is described by différent authors as 

 having a very smooth stipe and naked fronds; the few spécimens of 

 ^he Buitenzorg Herbarium, as far as still provided with a stipe, fit the 

 descriptions of those authors. The spécimens quoted hâve the fronds more or 

 less copiously pedately divided with 5—9 (rarely to 1 1) pinnae (i.e. primary 

 and secondary branches); ultimate segments entire to crenate or serrate.

 squamae firmae sed mox erosae vel dilaceratae et plus minusve deciduae, 

 basibus persistentibus, conspicue tuberculiformibus. Frondes usque 75 cm.

C, A. Backer's No. 9638 from J a v a (Mt G i 1 a p, ait. 2000 m.) resembles 

 this variety very much; the stipe of the speciinen, however, is wanting in 

 the Herbarium.
