Notes: A medium-sized (775 species in 6 genera) family of some small trees and shrubs, but mostly herbs with tubers or bulbs; they occur from the tropics to a few in temperate areas; oxalates are usually accumulated and the leaves are often folded together at night. The family contains Averrhoa carambola L. (CARAMBOLA, STARFRUIT), a tropical Asian tree cultivated for its fruits; the fruits, which resemble giant fleshy Oxalis fruits, are now commonly available in supermarkets. (subclass Rosidae)
