위키 설명
Phalaenopsis amabilis, commonly known as the moon orchid or moth orchid in India[7] and as anggrek bulan in Indonesia,[8] is a species of flowering plant in the orchid family Orchidaceae. It is native to the Indonesia and Australia, and widely cultivated as a decorative houseplant. It is an epiphytic or lithophytic herb with long, thick roots, between two and eight thick, fleshy leaves with their bases hiding the stem and nearly flat, white, long-lasting flowers on a branching flowering stem with up to ten flowers on each branch.
Description
Phalaenopsis amabilis is an epiphytic, rarely lithophytic herb with coarse, flattened, branching roots up to 1 metre (3.3 ft) long and usually 3–4 millimetres (0.12–0.16 in) wide. Between two and eight fleshy, dark green, oblong to egg-shaped leaves 150–300 millimetres (5.9–12 in) long and 40–70 millimetres (1.6–2.8 in) wide are arranged in two rows along the stem. The stem is 100–300 millimetres (3.9–12 in) but hidden by the leaf bases. The flowers are arranged on a stiff, arching flowering stem 300–750 millimetres (12–30 in) long emerging from a leaf base, with a few branches near the tip. Each branch of the flowering stem bears between two and ten white, long-lasting flowers on a stalk (including the ovary) 20–35 millimetres (0.79–1.4 in) long. Each flower is 60–70 millimetres (2.4–2.8 in) long and 50–80 millimetres (2.0–3.1 in) wide with the sepals and petals free from and spreading widely apart from each other. The sepals are egg-shaped, 30–40 millimetres (1.2–1.6 in) long and about 20 millimetres (0.79 in) wide and the petals broadly egg-shaped to almost square, 30–40 millimetres (1.2–1.6 in) long and wide. The labellum is white with yellow and reddish markings, about 25 millimetres (0.98 in) long with three lobes. The side lobes curve upwards and partly surround the column. The middle lobe is cross-shaped with a rounded tip and two long, thread-like wavy arms. There is a large yellow callus near the base of the labellum. Flowering time depends on distribution but occurs from April to December in New Guinea.[9][10][3][11]
Subspecies
There are three subspecies of P. amabilis recognised by the World Checklist of Selected Plant Families:
Phalaenopsis amabilis subsp. amabilis[4] which is the most widespread subspecies and is distinguished from the other subspecies by its cross-shaped labellum middle lobe, the base of which has yellow and red markings;[17]
Phalaenopsis amabilis subsp. moluccana (Schltr.) Christenson[5] which has a linear-oblong labellum middle lobe, with a slight dilation at its base where there are yellow and white markings;[17]
Phalaenopsis amabilis subsp. rosenstromii (F.M.Bailey) Christenson[6] which has a relatively short, triangular labellum middle lobe where the markings are yellow;[17]
In Australia, subspecies rosenstromii is recognised as Phalaenopsis rosenstromii by the Australian Plant Census.[18] It was discovered by Gus Rosenstrom "on trees, high from the ground, Daintree River" and was first formally described by Frederick Manson Bailey who published the description in the Queensland Agricultural Journal.[19][20]
Distribution and habitat
Phalaenopsis amabilis usually grows on trees, rarely on rocks, in rainforest where the humidity is high but there is free air movement. Subspecies amabilis has the widest distribution and occurs from Palawan in the southern Philippines to Borneo, Sumatra and Java. Subspecies moluccana is separated from subspecies amabilis by the Wallace Line and is found in Sulawesi as well as Seram and Buru in the Moluccas. Subspecies rosenstromii is native to New Guinea and Australia where it occurs on the Cape York Peninsula between the Iron Range and the Paluma Range National Park. It is separated from subspecies moluccana by Lydekker's Line.[9][17]
