7. T. museoides 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. (. aureum (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 
2 mill.) of the shape called ,Traufelspitze* 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. Y. 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 8. China, not 
yet found in America. 
Anthrophyum Kaulfs. 
10. A. reticulatum Klfs, 
Klong Sarlakpet, on rocks in the jungle near a waterfall. 
Area: Epiphytie on trees throughout the monsoon-region from N. India 
and Ceylon to Polynesia and N. Australia. 
Taenitis Smith. 
1). T. blechnoides Sw. 
Terrestrial in the jungle near Klong Munsé. 
Area: A Monsoon-plant from Ceylon and N. India to Polynesia. Earth-fern.
