Poncirus trifoliata
Trifoliate Orange
The primary subject is a woody plant identified as Trifoliate Orange. This identification is based on the highly diagnostic trifoliate compound leaves, where each leaf consists of three distinct leaflets, a key feature distinguishing it from true citrus species which have unifoliate leaves. Additionally, the presence of large, globose, yellow fruit with a bumpy rind is characteristic of this species, a close relative of citrus often used as a rootstock.
Overview
Conservation
Not evaluated
The trifoliate orange, Citrus trifoliata, is a member of the family Rutaceae. Whether the trifoliate oranges should be considered to belong to their own genus, Poncirus, or be included in the genus Citrus is debated. The species is unusual among citrus for having deciduous, compound leaves and pubescent (downy) fruit.
