Diagnostics:

Rubus moluccanus is a climbing, scrambling or creeping shrub of about 6-10m. The stem possesses prickles and is covered in dense hairs when young. The leaves are multi-lobed and finely serrated along the margins. The variety angulosus can be differentiated from others from the cordate leaf base, with the basal lobes touching or overlapping each other (Ang et al., 2010).


Interesting Facts:

Rubus moluccanus var. angulosus was previously declared extinct locally, but Ang et al. (2010) found that this was due to the misidentification of herbarium specimens to Rubus moluccanus var. moluccanus.
