55. Drynaria sparsisora (Desv.) Moore; G. Chr. Ind. 249; D. Linnaei 

 (Bory) Bedd.; Christ, 1. c. 106, — (no. 227, 726). 



Differs from D. quercifolia mainly by the scales of the rhizome being 

 peltately fixed. 



56. Acrostichum aureum L. var. Schmidtii Christ ; Chrysodium aureum 

 var. Schmidtii Christ, 1. c. 104, — (no. 718 h). 



57. Platycerium coronarium (König) Desv.; C. Chr. Ind. 664; P. 

 Uforme Sw. ; Schmidt, Bot. Tidsskr. 24: 105. (Specimens not seen.)

59. Gleichenia linearis (Burm.) Clarke; Christ, 1. c. Ill, — (no. 770). 



var. subpectinata (Christ); G. subpectinata Christ, 1. 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 

 pinnæ, 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 pinnæ 

 of the type-specimens. 



60. G. laevigata (Willd.) Hook.; Christ, 1. c. Ill, — (no. 770 bis). 

 Area: Malaya. Specifically different from the Mascarene G. flagellaris Spr. 



61. Schizaea digitata (L.) Sw.; Christ, 1. c. 112, — (no. 679). 



62. S. dichotoma (L.) Sm.; Christ, 1. c. 112, — (no. 710).

65. L. salieifoliuin Pr. ; C. Chr. Ind. 413. L. flexuosum Christ, 1. c. 

 112 (non Sw.), — (no. 11 [Lem Ngob], 830 [Koh Chang Noi]). 



Area: India, Malaya. 



66. Angiopteris evecta (Forst.) Hoffm. sp. coll.; Christ, 1. 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 pinnæ are remarkably long-stalked 

 (petiole 10 cm. 1. by a blade about 30 cm. 1.); pinnules 5 — 7 jugate
