Tab. IV. 



A. frondiLus longe stipitatis oblongo - lanceolatis elongatis 

 utrinque acutis coriaceis sub-marginatis parallelo - venulosis 

 glabris, fertilibus longissime stipitatis brevioribus conformibus 

 aut obtusiusculls , stipitis basi caudiceque paleaceis. Blume FiL 

 Jav, p. 100. I. 



Habitat : In Javd occidentali^ declivia borealia montis ignivom: Gede, 8000-9000 ped. supra mare edita, 

 inliabitans, ubi frequentissimum in jugis, qnre massls basalticis conformata, inquilinis Goenoeng Batoe (saxeus 

 mons) vocantur, cum mullis aliis cryptophytis rupes quam maxime stcrilcs vcgetationi uberiori prceparare 

 videtur. Etiam inter plantas, quas Ruhl et vah Hasselt montibus Karang Javce , allitudine 5ooo ped. , lege- 

 runt, specimcn hujus plantas paullo minus, marginibus revolutis stipiteque frondis fertilis nigro-maculato 

 hospitatur. A lalifoUo Sw. perquam affine, fronde sterili conformi, solum aliquantulo minore [in isto ovato- 

 lanceolata) diffcrt, prouti ab A. longifolio Jacq. fronde fertili minime spirali revoluta, imo constanter plana, 

 et ab A. simplicc Sw. frondc marginata discrepat.
