was less dense and less high and was gradually replaced by ferns, 

 whilst here and there a specimen of Ficus was growing. At two o'clock 

 in the afternoon a height of 475 m. was reached, where the explorers 

 made their camp for the night. 



The following day, May 10th, Demmeni alone continued the 

 trip and succeeded at last in reaching the top. The 3 tree-ferns 

 mentioned above, the only ones found, were growing at an altitude 

 of about 600 m. On the top there were no trees but herbaceous 

 ferns, intermixed with a few shrubs and with Saccharum. 



Here beneath I give a complete survey of the plants observed 

 by me in 1908 in the interior. 



Polypodiaceae. 



/. Dryopteris seticjera O. A. See p. 57, under No. 8. 



Scattered in open places in the Sacc/iamm-girdle. Numerous 

 on the steep walls of the gullies and ravines above an 

 altitude of 50 m. 



2. Dryopteris unita O. A'. See p. 56, under No. 7, 



Scattered in open places in the Saccharum-gird\e. Numerous 

 on the steep walls of the gullies and ravines above an 

 altitude of 50 m. 



3. Nephrolepis exaltata Schott. See p. 56, No. 6. 



Several groups at an altitude of 275 m. on and near a 

 humid stony cataract. 



4. Polypodium phymatodes L. 



Epiphytic or less often terrestrial fern, spread throughout 

 )ava from the plains till an altitude of 1500 m., on the whole 

 rather common, but absent or scarce in many regions where 

 the east-monsoon is very strong. It prefers a moderately 

 shadowed habitat. The reproduction is effected by spores 

 and by ramification of the rather long rhizome. 



Some scattered epiphytical specimens in ravines at an 

 altitude of 200 m. 



5. Polypodium punctatum Sw. 



Epiphytic fern spread from West- to East-Java, from the 

 plains to an altitude of 1500 m., except in regions where 

 the east-monsoon is very strong. The reproduction is exclu- 

 sively effected by spores.
