Fig 1. Matrices with the results of Discriminant Analysis for the three models (Adult, Young and Combined) and using average of 12 readings (abaxial+adaxial), and for both all wavelengths (left) and stepwise selected wavelengths (right).

The observed species names are given in columns, while predicted names are given in rows. Therefore, the values on the diagonal are correct predictions, and off-diagonal values are wrong predictions. Abbreviations: C. rho = Crepidospermum rhoifolium; P. api = Protium apiculatum; P. dec = Protium decandrum; P. gra = Protium grandifolium; P. heb.A = Protium hebetatum forma A; P. heb. B = Protium hebetatum forma B; P. kru = Protium krukoffi; P. occ = Protium occultum; P. pal = Protium pallidum; P. pan.n = Protium paniculatum var. nova; P.pan.r = Protium paniculatum var. reidelianum; P. sag = Protium sagotianum; P. sub = Protium subserratum.
