Castor oil plant

Castor oil is derived from the seeds of Ricinus communis (Castor bean plant) - a perennial, tropical flowering plant. 

Notable characteristics of the plant: 

1. Perennial, tropical, flowering plant (Wikipedia). 

2. While it is indigenous to India, Southeastern mediterranean basin and Eastern africa; it is widespread throughout other tropical regions. 

3. Castor oil plant is the only species in genus Ricinus (Wikipedia). 

4. "Fast growing, suckering shrub, around 12 meteres in height" (Wikipedia). 

5. "Glossy leaves, 15–45 centimetres (6–18 inches) long, long-stalked, alternate and palmate with five to twelve deep lobes with coarsely toothed segments" (Wikipedia). 

6. "Flowers lack petals and are unisexual (male and female) where both types are borne on the same plant (monoecious) in terminal panicle-like inflorescences of green or, in some varieties, shades of red. The male flowers are numerous, yellowish-green with prominent creamy stamens; the female flowers, borne at the tips of the spikes, lie within the immature spiny capsules, are relatively few in number and have prominent red stigmas" (Wikipedia).

7. "Fruit is a spiny, greenish (to reddish-purple) capsule containing large, oval, shiny, bean-like, highly poisonous seeds with variable brownish mottling. Castor seeds have a warty appendage called the caruncle, which is a type of elaiosome. The caruncle promotes the dispersal of the seed by ants (myrmecochory)" (Wikipedia).
