Anctor speciei (Grisebach, Symb. Flor. Arg., p. 123) 

 descriptionem parum snfficientem tradidit; flores non cogno- 

 visse videtur. Pitbecolobia vero difficillimum est verbis bene 

 describere, quamobrem Michelio, quod in plantis Balans^ 1427 

 et 1428, ut supra dixi, examinandis, erraverit, excusandum est. 

 Hoc loco, adjecta tabula (fig. 13), descriptionem accuratam 

 addere liceat:
