Family: Arecaceae    棕櫚樹

通用名稱: Totai Palm

枝條抗寒性區: 8b     英國和美國的地帶地圖

A solitary, large, drought tolerant, alkaline soil tolerant, moderately fast growing, monoecious palm. Rare in cultivation, locally common in the wild. It has a spiny, black trunk, 10 m. (33 ft.) tall, 38 cm. (15 inch) diameter with no obvious leaf scars, and large segmented, pinnate (feather) leaves, 3.7 m. (12 ft.) long, 1.5 m. (5 ft.) wide, green above and beneath.

The trunk is columnar and straight but occasionally has a slight bulge in the middle. A. aculeata sp. totai is armed with 12-13 cm (5-5½ in) black needlelike spines in closely set rings covering most of the trunk. This is the cold-hardiest form of Acrocomia aculeata.

Acrocomia totai can tolerate freezing temperatures to about -6.5°C (20.3°F). However, this is not a norm., and ideally you should not try to subject this palm to these temperatures. This is a species from dry grassland savannahs, open forests, or low montane environments, it should be grown in open sunny positions. You can try growing it in an understory position under a tree canopy to help protect the palm from serious cold, but we advise a south-facing position where the palm can catch as much of the winter sunshine as is possible.

鑑別:
