Three, growth and distribution

Orchidium multiflorum is native to tropical and subtropical regions of China, distributed in Hainan, Guangdong, Taiwan and other places. Sex like shade, afraid of direct sunlight, like moist, avoid dry, like fertile, rich in a lot of humus slightly acidic sandy loam. Born in the edge of the forest or valley stream?

Function

The roots and rhizomes of the orchid can be used as medicine, with the effect of moistening the lungs, relieving cough, clearing away heat and inducing dampness, and are mainly used for the treatment of lung-heat cough, whooping cough, hemoptysis of tuberculosis, and urinary tract infections. Because of its colorful flowers, elegant flowers, so it has a high ornamental value, can be potted for indoor viewing.

V. Morphological characteristics

Multiflora orchid is an epiphyte of the genus Orchidaceae, pseudobulb nearly cylindrical, 1.5 to 2.5 cm long, about 1 cm wide, enclosed in the persistent leaf base. Leaves 2～4, suberect, rectangular-oblanceolate, thicker leathery, 22～27 cm long, 3.5～4.7 cm wide, apex acute or obtuse, with a conspicuous midvein, the base obviously stalked; petiole slender, 15～23 cm long, 4～5 mm wide, grooved on the ventral surface, joints are located in the near middle .

Scape sheathing from base of pseudobulb, suberect or recurved, 16-28(~35) cm long; inflorescences usually with 10-40 flowers; bracts small; flowers denser, 3-4 cm in diam, generally unscented; sepals and petals reddish-brown or occasionally greenish-yellow, rarely grayish-brown, labellum white with purplish-red patches on lateral and middle lobes, pleats yellow; sepals narrowly oblong, 1.6-1.6 cm long, with a distinct midvein. 1.6-1.8 cm, 4-7 mm wide; petals narrowly elliptic, 1.4-1.6 cm, sepals subequal in width; labellum subovate, 1.6-1.8 cm, 3-lobed; lateral lobes erect, papillose; middle lobe slightly recurved, also papillose; 2 longitudinal folds on labellar disk, folds connivent at ends; stigmatic column 1.1-1.4 cm, slightly curved forward; pollinia in 2, triangular.

VI. Differences between Near Species

Cymbidium floribundum and Cymbidium suavissimum are not only similar in the form of leaf blades, but also have erect flower stalks and more than 50 stalks of flowers, which make them easy to be misidentified. Their differences are:

1 the color of the flowers, the fragrance is different

Multiflora orchid flowers for the reddish-brown, while the fruit of the orchid for the yellowish-green; multiflora orchids have no fragrance, while the fruit of the orchid orchid has a fruity aroma.

2 different flowering period

Multiflora orchids bloom 1 month earlier than fruity orchids.

3Leaves are different

Pseudobulbs of Orchidium multiflorum are inconspicuous, while those of Orchidium fructus are long and large. The leaves of Orchidium multiflorum are fewer and shorter; the leaves of Orchidium fructus are more numerous, longer and wider. The basal joints of the leaves of Orchidum are distinct and entire, while the bases of the leaves of Orchidum are united and entire.

4Differences in Distribution

Multiflora orchids are distributed in Fujian, Guangdong, Guangxi, Guizhou, Yunnan, Tibet and Southeast Asia Peninsula, and India; while Fructus Versicolor orchids are only distributed in Yunnan and Myanmar.

VII. Protection Level

Listed in China's List of National Key Wild Plants for Conservation - Grade II, listed in the Washington Convention (CITES) - Appendix II. Included in the IUCN Red List of Threatened Species (IUCN) - Vulnerable (VU).
