In to other localities, however, there was good molecular evidence of interspecific hybridization and resultant chloroplast introgression (Fig. 1)
Intereatingly, in neither case was there morphological evidence of hybridization .
On the island of Palawa, both accessions of C. mitis included in this study showed plastid genotypes most similar to that of the sympatric C. cumingii
In contrast, all accessions of C. mitis from other localities were resolved as a monophyletic groupvdistinct from the C. cumingii subclade.
Although these two species are morphologically similar, leaf material used in this study was derived from complete collections (Hanh 1993)
