(Bory) Bedd.; Christ, 1. c. 106, -— (no. 227, 726). 
Differs from D. quercifolia mainly by the scales of the rhizome being 
peltately fixed.

var. subpectinata (Christ); G. subpectinate Christ, |. c. (no. 619 f). 
Christ’s new species can hardly be other than a local form of 
the variable G. linearis. The reduction of the lower segments of the 
pinne, believed by Christ to be a characteristic feature of G. subpectinata, 
is not rarely seen in G. linearis and is, moreover, not found in all pinne 
of the type-specimens. 
60. @. laevigata (Willd.) Hook.; Christ, 1. c. 111, — (no. 770 bis). 
Area: Malaya. Specifically different from the Mascarene G. flagellaris Spr.

Area: India, Malaya. 
66. Angiopteris evecta (Forst.) Hoffm. sp. coll.; Christ, ]. c. 112, 
— (no. 767). 
The form collected is abundantly different from the true A. evecta 
from Tahiti. It belongs to the section Pseudangiopteris Pr. to which de 
Vriese referred about 30 ‘species’, most of them from India. I have tried 
to determine the Siamese form after de Vriese’s monograph; it does 
not agree exactly with any of the forms described by de Vriese, but it 
comes very near to A. repandula de Vriese, Mon. 30 t. 3,f. 4, t. 4,f. 4, 
differing from that form by the presence of very short recurrent veinlets 
and fewer sporangia in the sori. The pinne are remarkably long-stalked 
(petiole 10 cm. 1. by a blade about 30 cm. 1.); pinnules 5—7 jugate
