Pomelo is a low-branching, evergreen tree growing 5 - 10 metres tall with occasional specimens up to 15 metres. The spreading branches bear spines up to 5cm long, though there are some forms in cultivation that are free of spines.The tree is widely cultivated for its edible fruit in tropical and subtropical regions. It is especially popular in Thailand where a range of excellent quality cultivars have been developed. These forms are usually small trees with a spreading habit; fruit with thin rind and firm, crisp flesh, not very juicy; fruit often seedless or with shrivelled seed
