Dioclea mollicoma
Dioclea mollicoma
Safety & Hazards
The plant contains rotenone[1]. Rotenone is classified by the World Health Organization as moderately hazardous. It is mildly toxic to humans and other mammals, but extremely toxic to many insects (hence its use as an insecticide) and aquatic life, including fish. This higher toxicity in fish and insects is because the lipophilic rotenone is easily taken up through the gills or trachea, but not as easily through the skin or the gastrointestinal tract. The lowest lethal dose for a child is 143 mg/kg, but human deaths from rotenone poisoning are rare because its irritating action causes vomiting. Deliberate ingestion of rotenone, however, can be fatal. The compound decomposes when exposed to sunlight and usually has an activity of six days in the environment.

Propagation
The seed has a very tough seedcoat and a firm flesh. Many species in the genus grow near rivers or the sea and their seeds can be carried for many months over long distances in the water, whilst retaining viability. It is believed that the seed of some species can retain viability for over 100 years in the soil so long as the seedcoat is not damaged. In order to get the seeds to germinate within one's own lifetime, it is generally necessary to damage the seedcoat without damaging the flesh inside. This can be done quite easily by either cutting a notch into the seedcoat, or abrading it with sandpaper. Once this is done, soak the seed for 12 hours in warm water and it should germinate quite quickly[PFAF].
