P. aparinoides H. & A., the third, Mandon 839, to which the name 

 must be restricted, a distinct Bolivian species. 



P. nutkana Moc. ex DC. Prod. i. 330 (1824); A.DC. Calq. Dess. 

 t. 39. A very dubious species, perhaps Mexican. See Robinson in

 bunt ha of Hebecarpa, but not identifiable from description. 



P. platycarpa Benth. Recorded by Bennett, 1. c. 139 (1879). I 

 have not seen his specimens (Liebmann 32-35, Galeotti 881). 

 Hemsley and Chodat both erroneously accredit the original Hartweg

P. trichosperma L. Sys. XII. ed. hi. 232 (1768). South American;
