Houstonia (plant) Houstonia (plant) Houstonia (bluet) is a genus of plants in the family Rubiaceae. Many species were formerly classified, along with other genera since segregated elsewhere, in a more inclusive genus "Hedyotis". Bluets are often small and delicate. For example, "H. rosea" may grow only one inch tall. Some species are single stemmed and others have multiple stems in bunches. Flowers are blue, purple, lavender, white, or rose, often with shades of one color present in an individual population. Flowers have 4 sepals, colloquially denominated "petals", a salverform corolla with 4 lobes, and an inferior ovary. Some species exhibit heterostyly. The
Cruciferous vegetables one another taxonomically, only by horticultural category of cultivar groups. Numerous other genera and species in the family are also edible. Cruciferous vegetables are one of the dominant food crops worldwide. They are high in vitamin C and soluble fiber and contain multiple nutrients and phytochemicals. Extensive selective breeding has produced a large variety of cultivars, especially within the genus "Brassica". One description of genetic factors involved in the breeding of "Brassica" species is the Triangle of U. Cruciferous vegetables contain glucosinolates which are under basic research for their potential properties of affecting some types of cancer. Glucosinolates are hydrolyzed
