ets and hedges, in secondary forests and on wood-borders. 

 The reproduction is effected by spores. 



Collected at an altitude of 300 m. According to Appendix 

 I to the Dutch and English texts (where this plant and the 

 next one are transferred to the Polypodiaceae) the correct- 

 ness of the determination was liable to doubt. 



25 (57). Lygodium scandens Sw. 



Rather robust twining terrestrial fern, from the plains up 

 to an altitude of + 1200 m. spread throughout the moister 

 parts of Java, in thickets, hedges and young secondary 

 forests. The reproduction is effected by spores. 



Collected in the lower ravines. ,,/Vo real forest plant" 

 (D. v. L). 



Marattiaceae. 



26 (68). Angiopteris evecta Hoffm. 



Gigantic terrestrial polymorphic fern-species, on account 

 of very unimportant characters and often with the aid of 

 herbarium-fragments only, broken up by authors in a host of 

 minor species that nobody, not even they themselves, can 

 distinguish with certainty. The plant is spread throughout 

 Java between 250 and 1800 m. above sea-level in humid, 

 often densely shadowed ravines, especially along or near 

 water-courses. The reproduction is effected by spores and 

 very often by buds which develop on the big stipular ap- 

 pendices at the base of the petiole after these appendices 

 have fallen off from the short thick trunk ') 



Collected in the lower ravines. 



Ophioglossaceae. 



27 (67). Ophioglossum reticu/atum L. (O. pedunculosum Desv.; 



recorded in Appendix III to the Dutch text as O. pediculo- 

 sum Denv.). See pp. 109, H3. 



Collected at an altitude of 600 m. The Dutch text adds: 

 ,,Penzig 187, when the forest did not yet exist". The English 

 text omits this addition.
