C. annuum seeds tend to be more reniform or kidney-shaped with a small protruding beak that extends approximately 50-65° from the seed body. Out of all the Capsicum domesticates, C. annuum has the smallest thick testa to thin testa ratio, meaning that the margins of the seed are much closer in size to the dorsal and ventral sides of the seed testa. C. annuum, like C. chinense and C. frutescens, also exhibits a very smooth testa texture, with little to no reticulation.
