Gaylussacia is a genus of flowering plants with about 50 species within the heather family, which is native to America , where it occurs in eastern North America as well as in the Andes and in the southeastern mountainous region of Brazil (with the majority of species) in South America. English common names are Huckleberry (which they share with various species of other genera) and dangleberry . The type species is Gaylussacia buxifolia Kunth.
ecology
Gaylussacia species are used by the larvae of some butterfly species such as Coleophora gaylussaciella (which can only be found on Gaylussacia ) and Coleophora multicristatella as food plants.
Gaylussacia plants are often found in oak heather forests in eastern North America. They are deciduous or evergreen shrubs with a height of 0.4–1.8 meters.
Little-flowered and racemose inflorescences are formed or the flowers appear individually. The flowers are four to five-fold with a double flower envelope. There are ten stamens. The multi-chambered ovary is subordinate.
Multi-seeded and fleshy, star fruit-like fruits are formed.
Systematics
The genus Gaylussacia was named in honor of the French chemist Joseph Louis Gay-Lussac (1778–1850). It is closely related to the genus Vaccinium , but it is still unclear whether the commonly drawn boundary between these genera can hold up on closer examination. A 2002 study found that the molecular data did not support the historical division of Gaylussacia into sections .
