Nota. Species valde dubia ex iconibus laudatis solum nota. Drupae icone illustratae, nisi 

 auctae, 5 cm longae 4 cm latae essent; syncarpium 50 cm longum 35 cm latum esset, maximum 

 ergo genoris idquod vix probabile mihi videtur; drupam multo minorem et ei P. utilis vel P. 

 Stuhlmannii similem esse suspicor. Species apice druparum prorsus piano, stigmatibus stellatis, 

 drupis quadrangulis persingularis, forsan P. reflexo affinis. In insulis Africae orae orientalis vel in 

 Africa continentali nee (utBrongniart affirmat) in insulis indicis (Nicobar.) eam crescere puto. 

 Gaudichaud speciem cum P. leram commiseuit, idquod ex icone eius (flg. 1 et forsan fig. 5 — 7) 

 apparet; itaque nomine »Roussinia indica* appellata est. Fig. 4 — 4 seeundum Jones (in Asiat. 

 Researches IV. [1 793] 165) reiteratas, fig. 5—9 seeundum speeimina originaria P. palustris in Museo 

 parisiensi asservata delineatas esse Balfour (in Journ. Linn. Soc. XVII. 66) affirmavit.
