위키 설명
Phoenix roebelenii, with common names of dwarf date palm,[1] pygmy date palm, miniature date palm or robellini palm, is a species of date palm native to southeastern Asia, from southwestern China (Yunnan Province), northern Laos and northern Vietnam, (in Dien Bien Province, Ha Giang Province, Cao Bang Province, Lang Son Province).[2][3]
The Latin specific epithet roebelenii honours the orchid collector Carl Roebelen (1855–1927).[4]
Description
Phoenix roebelenii is a small to medium-sized, slow-growing slender tree growing to 2–7 metres (6.6–23.0 ft) tall. The leaves are 60–120 cm (24–47 in) long, pinnate, with around 100 leaflets arranged in a single plane (unlike the related P. loureiroi (산대추야자) where the leaflets are in two planes). Each leaflet is 15–25 cm (6–10 in) long and 1 cm wide, slightly drooping, and grey-green in colour with scurfy pubescence below.
The flowers are small, yellowish, produced on a 45 cm (18 in) inflorescence. The fruit is an edible 1 cm drupe resembling a small, thin-fleshed date.[5]
This Palm produces strong, spiny thorns approx. 2-4" in length. The size of the thorns depends on the age of the tree. These thorns are located on the Palm Leaf stem close to the truck and can may extend 6-12" from the trunk. The thorns are very sharp and easily penetrate the skin. They are poisonous and can cause irritation, skin infection, bruising and can be severe. They can also cause an allergic reaction. These reactions differentiate on the exposure.
Cultivation and uses
Phoenix roebelenii is a popular ornamental plant in gardens in tropical and subtropical climate areas. With a minimum temperature requirement of 26 °F (−3 °C) it is grown under glass or as a houseplant in cooler areas.[6] It needs little pruning to develop a strong structure, is resistant to pests, is tolerant to soil variation, and is moderately drought tolerant. The plant grows in partial shade to full sun, with the local climate determining where to plant.
This plant has gained the Royal Horticultural Society's Award of Garden Merit.[7][8]
The NASA Clean Air Study concluded that this was a plant that was effective at removing common household air toxins formaldehyde and benzene.
Palmpedia 설명
The pygmy date palm is one of the most popular small landscape palms in Florida. It is single-stemmed, but is often grown in clumps of 2–4 closely spaced individuals which, when older, give the impression of a multi-stemmed palm (Figure 1). It grows to a height of about 12 ft with a spread of 6–8 ft. The feather-shaped (pinnate) leaves have slender petioles and basal leaflets that are modified into sharp 2–3 inch long spines. The slender, often crooked trunk varies in diameter from 3–6 inches and is covered with distinctive peg-like leaf bases (Figure 2). Older specimens will have a large mass of aerial root initials at the base of the trunk. Cream-colored male and female flowers are found on separate trees (dioecious) in the spring that are followed by small elongated reddish-brown fruits that turn black upon ripening. (Dr. Timothy K. Broschat - edis.ifas.ufl.edu)
In its natural environment Pygmy Date Palm has a single-trunk, but in cultivation it is usually planted with 3-5 specimens. When planted in clumps, the trunks tend to curve gracefully away from the center of the clump creating an especially attractive arrangement.
The Pygmy Date Palm trunk is covered with old leaf scars and topped with pinnate, or feather like, leaves which grow to about 4ft in length. Leaves are bright green, droopy covered with 4-5 in leaflets that are modified into 2-3 in. sharp spines at the base of the petiole. Be careful while pruning it and keep kids away.
Flowers/Fruits: During spring, the Pygmy Date Palm produces beautiful creamy flowers that are held by 1ft long stalks. The Pygmy Date Palm is dioecious, male and female flowers grow on separate plants. Between september and october, flowers are followed by small dates. It usually has about 10 -13 long fruit clusters hanging below the leaves. Fruits are elliptical, 1/2 inch long and turn red-brown to dark purple when ripe. The date is mostly seed with only a thin layer of fruit. (florida-palm-trees.com)
