Notes

The leaves are variously reported as bitter ('amara'), to which also the Sundanese name 'pait' refers, bittersweet ('dulcamara'), or sweet tasting. This and the groove over the midvein most readily distinguishes it from similar-leaved associated Podocarpus species while the lack of hypoderm also gives a distinct texture to the leaves. The striking form of the juvenile leaves led to the description of Podocarpus eurhyncha. GRAY & BUCHHOLZ (1951) report that the leaves occasionally have a lateral pair of vascular resin canals in addition to the conspicuous central canal beneath the vascular bundle. Two collectors report seeds with distinctive sculpturing on their surface but this is not evident in the corresponding preserved specimens. The normally three rather than two fused pairs of cotyledons is unique. The limited occurrence in Borneo is curious.
