Abstract

A study on leaf morphological variation in Pisonia grandis R.Br. from Java, Bali, and Lombok was conducted to assess patterns of intraspecific variation. Sixteen specimens were examined, all of which exhibit entire leaf margins, predominantly chartaceous textures, and a prominent abaxial midrib. Variation was detected across 15 leaf characters. Phenetic analysis revealed three major groups at a similarity coefficient of 0.45. Group A comprises two subgroups (A1 and A2) at a similarity coefficient of 0.52. Group B is also divided into two subgroups (B1 and B2) at a similarity coefficient of 0.45, while Group C consists of two subgroups (C1 and C2) at a similarity coefficient of 0.59. The cluster analysis does not support recognition of any infraspecific taxa, as the observed morphological variation does not correlate with geographic distribution.
