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 many have exceptional heat. The hottest peppers in the world are members of this species, with Scoville Heat Unit scores of over 2 million. Some taxonomists consider them to be part of 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 correct. The two species can also hybridize and generate inter-specific hybrids. It is believed that C. frutescens is 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 they originated in China due to their prevalence in Chinese cuisine after their introduction by European explorers. 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 in height. The flowers, as with most Capsicum species, are small and white with five petals. When it forms, the fruit varies greatly in color and shape, with red, orange, and yellow being the most common mature colors, but colors such as brown and purple are also known. Another similarity with other species would be shallow roots, which are very common. Distribution C. chinense origin is not an easy matter to settle. However, several reports by McLeod, Pickersgill, and Eshbaugh put its center of origin in the tropical northern Amazon, ranging from Southern Brazil to Bolivia (Eshbaugh, W.H.1993. History and Exploitation of a serendipetous new crop discovery. p. 132-139. In: J. Janick and J.E. Simon (eds), New Crops. Wiley, New York). Later on, it migrated to the Caribbean basin and Cuba originating the term Habanero, meaning from Habana (Havana, Cuba), where several peppers of this species were exported out from this port. (Despite the name, habaneros and other spicy-hot ingredients are rarely ever used in traditional Cuban cooking.) In warm climates such as these,
