[hide]Description[edit]
A. arborescens is a large shrub or tree up to 10 meters in height. It flowers in clusters on naked branch parts below the leaves. Leaves are alternate, simple, elliptical, narrow to a long v-shape at the base, variably narrowed to a point at the tip, 15 to 30 cm long and 5 to 15 cm wide, margins entire or slightly wavy, hairless except when young. Young stems and young leaves have rusty hairs. The fragrant flowers bloom in clusters of 30 or more, with broadly funnel-shaped tubes about 1.2 cm long and recurving lobes. The protruding stamens are greenish-white to cream. The bright orange fruit is round, and about 1 cm across. They flower sporadically throughout the year, with fruit generally from March to July.[2]
Distribution and habitat[edit]
It is native to Central and South America, and the Caribbean. In Puerto Rico and the United States Virgin Islands, it is classified by the US Department of Agriculture as a native plant species.[3]
Ecology[edit]
A. arborescens contains a fragrant compound also found in roses and Narcissus tazetta called orcinol dimethyl ether that is almost undetectable to the human nose. However, experiments show that honeybees can readily detect it.[4]
Cultivation[edit]
A. arborescens is grown as an ornamental tree for gardens and natural landscaping projects to attracting various species of birds, a use from which it gets its Brazilian common name "thrush fruit".[5]
