The following is a list of cultivated species which at least some of the time possess this spot-character.
By this, we mean that the seed is partly coloured black and partly red. The red colour may be because of an aril (e.g. Afzelia quanzensis) or simply (apparently) a bicoloured seed as in Abrus precatorius.
