COWITCH; VELVETBEAN
**
**
This plant is notable for producing irritating hairs on its fruits, containing serotonin (a neurotransmitter) (Bowden et al. 1954) and mucanain (a cysteine protease) (Papoiu et al. 2011). However, some plants do not produce the irritants (Hammerton 2003). Both the non-irritating and irritating forms can be found in Florida .
