Cirus maxima or the Pomelo is an evergreen shrub to 4m tall, with glossy, oval leaves to 10cm long and fragrant white flowers to 4cm across that appear throughout the year.
The flowers that appear as single or in clusters are fragrant and yellow-white in color.
The large fruits (15–25 cm in diameter) are flattened-spherical to slightly pear-shaped, can be greenish or yellow and may weigh as much as 2kg. The rind is thick and tough and the flesh tastes like a gentle grapefruit, being not so bitter.
They are an excellent source of vitamin C, are eaten as a fresh snack, juiced or made into jams.
The fruit generally contains few, relatively large seeds, but some varieties have numerous seeds.[4]
