Context paragraphs:
Cuphea oil: Cuphea oil is oil pressed from the seeds of several species of the genus "Cuphea".  Interest in cuphea oils is relatively recent, as a source of medium-chain triglycerides like those found in coconut oil and palm oil.  Cuphea oil is of interest because it grows in climates where palms - the source of both of these oils - do not grow.

Cuphea elegans: Cuphea elegans is a species of flowering plants native to Brazil.

Lythraceae: Lythraceae is a family of flowering plants, including 32 genera with about 620 species of herbs, shrubs and trees.  The larger genera include "Cuphea" (275 spp.) , "Lagerstroemia" (56), "Nesaea" (50), "Rotala" (45), and "Lythrum" (35).  It also includes the pomegranate ("Punica granatum", formerly in Punicaceae) and the water caltrop ("Trapa natans", formerly in Trapaceae).  Lythraceae has a worldwide distribution, with most species in the tropics, but ranging into temperate climate regions as well.

Cuphea: Cuphea is a genus containing about 260 species of annual and perennial flowering plants native to warm temperate to tropical regions of the Americas.  The species range from low-growing herbaceous plants to semi-woody shrubs up to 2 m tall.  Commonly they are known as cupheas, or, in the case of some species, as cigar plants.  The generic name is derived from the Greek word κυφος ("kyphos"), meaning "bent," "curved," or "humped."

Michauxia: Michauxia is a genus of plants in the Campanulaceae.  It contains 7 known species native to southwestern Asia.

Cuphea ignea: Cuphea ignea (cigar plant, cigar flower, firecracker plant, or Mexican cigar) is a species of flowering plant in the genus "Cuphea" of the family Lythraceae.  It is a tropical, densely branched evergreen subshrub.  This species, native to Mexico and the West Indies, produces small, tubular, bright red to orange flowers.  Each flower is tipped with a thin, white rim and two small purple-black petals.  The flower is said to resemble a lit cigar, hence the name.  The leaves are small, elliptical and of a bright green colour.  It grows to about 60 cm .  The name "ignea" comes from the Latin for "fire".

Cuphea aspera: Cuphea aspera is a species of flowering plant in the loosestrife family known by the common names tropical waxweed and Chapman's waxweed.  It is endemic to Florida in the United States, where it is limited to Gulf and Franklin Counties on the central Florida Panhandle.  It has likely been extirpated from Calhoun County.
