Some specimens cited by Allen (J. Arnold Arbor. 23: 451. 1942) as Beilschmiedia roxburghiana (S. K. Lau 3147, A; S. K. Lau 27404, A; and K. Fung 20123, A, US) are, in fact, B. percoriacea (species no. 36), which is characterized by the whole plant being glabrous. Records from Hainan (in Fl. Hainan. 1: 278. 1964) are referable to B. appendiculata (species no. 15), which was included in the synonymy of B. roxburghiana in that work (as Lauromerrillia appendiculata).
