Wikipedia 설명
Archontophoenix alexandrae, commonly known as Alexandra palm, king palm, Northern Bangalow palm, or feather palm,[4][5][6] is a palm endemic to Queensland, Australia. It was named in honour of Princess Alexandra of Denmark,[7] but is often erroneously referred to by the misnomer Alexander palm.
Description
Archontophoenix alexandrae is a tall, solitary palm growing to a height of 30 m (98 ft) with a trunk up to 30 cm (12 in) diameter, often swollen at the base, and bearing prominent leaf scars.[4][5] The graceful crown has 8 to 10 pinnate, feather-like fronds that measure up to 4.5 m (15 ft) in length, with 60 to 80 leaflets on each side of the midrib.[4][7] The pinnae are dark green above and silvery-grey underneath, measuring up to 75 cm (30 in) long, and the entire frond is usually twisted laterally.[4][5] At the base of each frond is a large crownshaft up to 1 m (3.3 ft) high, coloured light green.[4]
Flowers
The inflorescence of Archontophoenix alexandrae is a panicle, creamy white when first released from the protective sheath or prophyll that it develops within, and transitioning through light green as the fruits develop and finally to brown when it is shed from the tree. It measures between 50 to 100 cm (20 to 39 in) wide by 50 cm (20 in) long, and arises from the base of the crownshaft.[4][5][7] Flowering occurs randomly throughout the year,[7] and it is not uncommon to find a group of these palms, some of which carry fruit and/or flowers while others carry neither. Individual flowers are 3-petalled, creamy-white in colour and quite small—the staminate (functionally male) flowers measuring up to 10 mm (0.39 in) wide and the pistillate (functionally female) flowers up to 4 mm (0.16 in).[4]
Fruit
The fruits are ovoid to globose with a persistent calyx. They are initially green turning bright red when ripe. They measure around 10–14 mm (0.39–0.55 in) in diameter and contain a single seed about 8 mm (0.31 in) diameter.[4][7]
Taxonomy
The species was originally described as Ptychosperma alexandrae by Ferdinand von Mueller in his Fragmenta phytographiae Australiae in 1865.[8] In 1875 the German botanists Hermann Wendland and Oscar Drude published a treatment of Australian palms in the journal Linnaea titled Palmae Australasicae, in which this species was renamed Archontophoenix alexandrae.[9]
Etymology
The genus name is derived from the Ancient Greek ἄρχων (árkhōn), meaning "chieftain" or "ruler", combined with the palm genus Phoenix, and refers to the regal stature of the trees. The species epithet is given in honour of Princess Alexandra of Denmark.[7][10]
