Chrysophyllum albidum (commonly known as white star apple) is a forest fruit tree described by the Scottish botanist George Don.It is commonly found throughout tropical Africa.Amongst the Yoruba tribes of Nigeria, it is called Agbalumo while called Udala in the eastern and southern parts of Nigeria.It is closely related to the African star apple (Chrysophyllum africanum) which is also common throughout West Africa.Some schools of thought feel that they may just be a variety of the same species.Also in the family is the (purple) star apple (Chrysophyllum cainito).

The Chrysophyllum genus of plants consists of almost 80 different species of fruits all exclusively grown within the tropical region.African star apple (Udara) is a very popular fruit here in Nigeria.Its fleshy pulp is often eaten as a snack and it is equally common in both the urban and rural areas, particularly around Southern Nigeria.Udara fruit plants in Keralais now available in our farms.
