Malayan Fortunella polyandra (Ridl.) Tan. Kumkvat
Hedge, Chang ye jingan, Pagar
'Malayan' originates, as the name suggests, in Malaysia, but is also cultivated in China and Thailand. It's a tropical shrub or very small tree with typically lanceolate leaves that can be as long as 12cm. It has small flowers and spherical orange fruit (4-5cm long) with a thin rind. Its pulp is divided into several segments with very few seeds inside. Ripe fruit is primarily used for preparing refreshing drinks, but also as a spice. 'Malayan' is quite cold-hardy and is very suitable for growing indoors. It's a very decorative kumquat.
