A solitary, medium sized, water-loving, salt-tolerant, moderately slow growing, dioecious palm. Common in cultivation, locally common in the wild. It has a rough, grey-brown trunk, 12 m. (40 ft.) tall, 28 cm. (11 inch) diameter with no obvious leaf scars, and huge partially segmented, palmate (fan) leaves, 1.8 m. (6 ft.) long, 1.8 m. (6 ft.) wide, bluish-green above and, pinkish beneath.

This form produces larger fruits and seeds than the Chinese form. The fruits are 2.5 cm. (1 inch) long, ovoid with a beautiful turquoise-blue colouration. The leaf-crown is densely packed with 30 - 50 highly pendulous, bluish green to glossy olive green leaves.

Livistona chinensis var. subglobosa can survive freezing temperatures to about -6.5°C (20.3°F), but freezing is best avoided. This species naturally occurs on islands in moist forest, and is heavily effected by the surrounding sea temperatures, which are constant and often form sea mist and cloud. In this type of natural environment temperature fluctuations are slight, and this palm prefers a constantly mild climate with little temperature difference between day & night, and Summer & Winter. Under extreme freezing conditions we recommend you keep this palm as dry as possible, and well wrapped up.

鑑別:
This is a much more attractive form than the usual form of Livistona chinensis found in Southern China, and is also more cold-hardy. Livistona chinensis var. subglobosa is perhaps justifiably not deserved of subspecies status, as the morphological differences are slight when compared with the Chinese mainland form. The main noticeable difference is to be seen in the size and shape of the seeds. The mainland China form, which is the commonest form in cultivation around the world produces a typically elongate, smaller seed (15 - 9 mm) than the Japan/Taiwan form which produces a larger, more globose seed (18 - 12 mm).
