Natural History & Notes

This profile information and associated coding has been adapted from Jessup (2011), Harden et al. (2014), and Nooteboom (1982, 2004). The flowers of this genus are reported in Nooteboom (1982; 2004) and Jessup (2011) to be mostly bisexual but also functionally unisexual and dioecious, however this has not been specifically reported for this species.
