7. T. »i ü sco i ties Sw. 



Very typical, with flabellate cuneiform fronds and 3 to 5 sori. 



Nipple (500 ft.) and Klong Son, epiphytic on low trees. 



Area: Widely spread in all tropical regions. A small epiphyte on branches. 



I am rather puzzled by the wanting of all Hymenophylla in the col- 

 lection. 



Polypodiaceae. 



Chrysodium Fée. 



8. C. aiireiini (L.) Fée. 



This species is represented from Koh Chang by a characteristic variety : 

 Var. Schmidtii Christ n. var. 



Well distinguished by the barren pinnae which are cuspidated i. e. 

 tapering into a long linear very acute apex (long: 3 cent., large: hardly 

 û mill.) of the shape called „ Träufelspitze L by Stahl. 



I never saw this apparatus (a protection against overflowing rainfall) 

 in this species so developed as here. The fertile pinnae have only the 

 short mucro very common in this plant. 



Abundant throughout the island, most commonly in brackish water in the 

 interior of mangrove-swamps. 



Area: The species is nearly universal in brackish waters and estuaries of 

 the tropics and farther to Florida. 



Vittaria Sw. 



9. V. elongata Sw. 



On trees and rocks near the Sea, Lem Dan and more southward off Koh 

 Sarlak. 



Area: Epiphytic on trees from S. W. and N. W. India to S. China, not 

 yet found in America. 



Anthrophyum Kaulfs. 



10. A. reticulatuin Klfs. 



Klong Sarlakpet, on rocks in the jungle near a waterfall. 

 Area: Epiphytic on trees throughout the monsoon-region from N. India 

 and Ceylon to Polynesia and N. Australia. 



Taenitis Smith. 



1 1 . T. blechnoides Sw. 



Terrestrial in the jungle near Klong Munsé.
