Nothing can be said of No. 8, Davallia spec., No. 21, Poiypodium 

 spec., No. 32, Habenaria spec., No. 37, Qberonia spec., No. 39, 

 Liparis spec, and No. 40, Thrixspermum spec., of which plants only the 

 generic names are given. Species of these genera being found as well 

 out of forests as within them, it is impossible to decide whether they 

 are ,,real" forest-plants. 



Consequently of the 58 ,,real" forest-plants of Mr. Docters 

 van Leeuwen there remain at best 26 which as a rule occur in 

 rain-forests of some age. As to their habitat I refer to the list given 

 above. Those plants are: No. 1, Trichomanes humile Forst., No. 2, 

 Alsophila spec., No. 3, Dryopteris megaphyJ/a C. C/ir., No. 10, 

 Diplazium polypodioides Bl. (but also rather frequent in shadowed, moist 

 localities, out of forests), No. 11, Asp/enium nidus L. (frequently 

 found out of forests), No. 13, Antrophyum spec, (all Javanese species 

 of this genus), No. 17, Poiypodium accedens Bl., No. 18, Poiypodium 

 herac/eum Knze., No. 26, Angiopteris evecfa Hoffm., No. 29, 

 Lycopodium squarrosum Forst., No. 33, Per/stylus gracilis Bl., No. 36, 

 Oberonia monstruosa Lindl., No. 38, Liparis viridiflora Lind/., No. 42, 

 Trema orientate Bl. (very often also in deserted fields), No. 43, Ficus 

 ampe/as L. (frequently found in gardens and in native villages), No. 46, 

 Ficus lepicarpa Bl., No. 49, Ficus ribes Bl., No. 52, Ficus variegata 

 Bl. (frequently found out of forests), No. 53, Villebrunea rubescens 

 Bl., No. 54, Leucosyke capitellata Wedd., No. 61, Solarium blumei 

 /Vees (provided the determination be correct), No. 62, Radermachera 

 glandulosa Miq., No. 63, Trichosporum pulchrum Bl. (in moist regions 

 also frequent on trees in native villages), No. 65, Cyrtandra sulcata 

 Bl., No. 66, Nauclea purpurascens BL, No. 68, Gynura sarmen- 

 tosa D.C. (very often also out of forests.). 



Besides the five littoral species excluded without reason from 

 Appendix II and recorded already by me on p. 247, Mr. Docters 

 van Leeuwen mentions in Appendix I to his paper 11 or 12 other 

 species as found in 1919 on Krakatao which are not given in Appendix 

 II and III and therefore probably were neither found on or near the 

 beach nor were forest-plants, not even unreal ones. These species, 

 about the habitat of most of which we are left quite in the dark, are: 



Polypodiaceae. 



/. Dryopteris unita O.K. See p. 56, sub No. 7. 



According to 6, herebefore collected on the higher 

 ridges and on the top the mountain.
