ABOVE: A ripe green fruit of Parartocarpus venenosus the most common of the four Parartocarpus species found in Borneo. Parartocarpus are distinguished from Artocarpus by the persistent bracts found at the base of the peduncle (fruit stalk). Unlike the soft seeds of most Artocarpus species the seeds of P. venenosus have a hard bony endocarp indicating that they are orthodox or slow to germinate.
Like Antiaris toxicaria (Ipoh) also in the Moraceae family the latex is reputed to be so toxic that it was used as an arrow or dart poison in the past.
