Capsicum chinense, commonly known as a "habanero-type pepper", is a species of chili pepper native to the Americas. C. chinense varieties are well known for their unique flavors and, in many cases, exceptional heat. The hottest peppers in the world are members of this species, with a Scoville heat unit score of 2.69 million measured in the C. chinense cultivar Pepper X in 2023.
Some taxonomists consider C. chinense to be within the species C. annuum, and they are a member of the C. annuum complex; however, C. chinense and C. annuum pepper plants can sometimes be distinguished by the number of flowers or fruit per node – two to five for C. chinense and one for C. annuum – though this method is not always accurate. The two species can also hybridize and generate inter-specific hybrids. C. frutescens may be the ancestor to the C. chinense species.
Taxonomy
The scientific species name C. chinense or C. sinensis ("Chinese capsicum") is a misnomer. All Capsicum species originated in the New World. Nikolaus Joseph von Jacquin (1727–1817), a Dutch botanist, erroneously named the species in 1776, because he believed it originated in China due to its prevalence in Chinese cuisine; however, it was later found to have been introduced into China by earlier European explorers during the Ming dynasty.
Plant appearance
Within C. chinense, the appearance and characteristics of the plants can vary greatly. Varieties such as the well-known Habanero grow to form small, compact perennial bushes about 0.5 metres (1 ft 8 in) in height. The flowers, as with most Capsicum species, are small and white with five petals. A diagnostic feature of the species is the calyx of the fruit, which has a distinct annular constriction where it joins the stalk, and the plants tend to bear two or more flowers at each node, in contrast to Capsicum annuum, which usually bears a single flower per node. These characters are shared with the closely related Capsicum frutescens, and the two species can be...
