Flores hermaphroditi, nudi. Stamina 4; filamenta linearia latiuscula, antherae 

 thecis ovoideis, extrorsis, rima longitudinali basin non attingente dehiscentibus. Ovarium 

 obpyramidatum, tetragonum, uniloculare ; ovula 2 funiculo brevi infimae parti placentae 

 parietalis valde intus prominentis affixa, anatropa; stilus ovario crassior, vertice medio 

 leviter elevatus; stigma hemisphaericum parvum. — Herba Archipelagi indici prorepens 

 cauli tenui, remotiuscule anguste foliato, cellulis spiculiformibus intercellularibus sparsis 

 instructo. Foliorum petiolus canaliculatus, geniculo brevissimo canaliculato instructus, 

 lamina cordato-ovata vel cordata, rotundata, basi sinu semiovato profundo excisa, apice 

 acuminata, costa tenui, nervis lateralibus I. superioribus patentibus omnibus in nervös 

 collectivos sub-4 margini arcuatim approximatos conjunctis, nervis II. areolas majus- 

 culas constituentibus. Pedunculus erectus petioli dimidium aequans. Spatha conchiformis, 

 apiculata. Spadix sessilis, brevissimus. 



Nota. Cellulae spiculiformes intercellulares in hujus plantae cauli adsunt, attamen rarae. 

 In pistillis tales cellulas spiculiformes, quae in generum Eaphidophora , Epipremnum, Scin- 

 dapsus pistillis frequentissime occurrunt, haud observavi. Seminis structura incognita. Quum 

 etiam ovarii structura paullum ab illa generum Epipremnum et Scindapsus differat, melius 

 existimo, genus Amydrium Schott conservandum esse.
