Is a variant of Is a variant of Dendrobium, with the original variant is the difference between the plant is more stout, stems more than 4 mm thick, leaf width 1.8 to 4.5 cm, inflorescence length of 5 to 14 cm, 1.8 to 3 cm long bract, the upper lip Mask A large purple plaque, producing Hainan, Guangxi, southwest to northwest, southern Guizhou to the southwest, was born at an altitude of 600 to 2500 meters in the mountain forest in the trunk.
The difference from the original variant lies in that the plant is obviously thicker with stem thicker than 4 mm, leaves 1.8-4.5 cm wide, inflorescence 5-14 cm long, and flower buds 1.8-3 cm long, with a large purple plaque above the labial petals.
Stem slender, cylindrical, usually 25-35 cm long, 2-4 mm thick, unbranched, with many nodes; internodes 2.5-4 cm long, yellowish or yellowish brown. Leaves leathery, linear or narrowly oblong, 8-10 cm long, 0.4-1.4 cm wide, apex obtusely and pitted or sometimes acute and slightly rounded on one side, base sheathing; Inflorescences laterally erect, 0.5 cm long, basally nested 3-4 sheaths; sheaths proximally erect, lasts about 1 cm, usually 1-to 2 cm, sometimes 3-flowered; Papery, pale white, cup-shaped or tube-shaped, base shorter, gradually becoming longer and longer, 5-20 mm long; bracteoles membranous, pale white, boatlike, 1.2-1.3 cm long and 5 mm wide, Apex obtuse; pedicel and ovary ca. 3 cm; flowers orange-yellow, spreading; middle sepals oblong-elliptic, 2.3-2.5 cm long, 1.1-1.4 cm wide, apex obtuse, entire, with 5 veins; Round, as long as sepals and slightly narrower, apex obtuse, base slightly astigmatism, with 5 veins; calyx sac conical, ca. 6 mm; petals elliptic or broadly elliptic-obovate, 2.4-2.6 cm long, wide 1.4-1.7 cm, apex obtuse, entire, with 3 veins branched on main lateral veins; lip suborbicular, 2.5 cm long, 2.2 cm wide, with claw ca. 3 mm at base and Sometimes with several red stripes on the inside, the central below the two sides hold pistils, densely covered on the top of the hair with irregular serrated teeth, lips without any spot ; Gynostemium about 4 mm, about 3 mm, the stem foot; anther cap narrowly conical, about 4 mm, smooth, distal subtruncate. Flowering from May to June.
Origin distribution
Production of Hainan (Dam Wang Ling), Guangxi southwest to northwest (Lingyun, music industry, Fengshan, Jingxi, Germany Paul, Napo), southern Guizhou to the southwest (Xingyi, Luodian, Pingtang, Guanling, Huishui), Yunnan southeast to northwest (Pingbian, Yanshan, Jianshui, Menghai, Fengqing, Cangyuan, Lancang, Gengma, Zhenkang, Tengchong, Gongshan, Lijiang, , Deqin and other places). Born in an altitude of 600 ~ 2500 meters in the mountain forest in the trunk. Distributed in India, Nepal, Sikkim, Bhutan, Myanmar, Thailand, Laos, Vietnam. Specimens were collected from Laos.
Variants Edit Briefly
Dendrobium Lamina is a variant of Dendrobium. Dendrobium Dendrobium is a large species of domestic flowers, the most delicate stems. Production in Taiwan, central and southern Sichuan, Yunnan, southeast to the northwest, Myanmar, India is also more distributed. Dendrobium stem diameter 2 ~ 4 mm, leaf width 0.4 ~ 1.4 cm, flower orange, lip no any plaque.
In addition to the above variants, there are two monolayers of Dendrobium, producing southern Sichuan to the middle of the sepals with a pale purple halo, there are two purple patches.
