Dendrobium findlayanum Par. Et Rchb. F.
Dendrobium findlayanum Par. Et Rchb. F. is a perennial herbaceous plant that prefers shade and prefers to grow in warm, humid environments with an annual rainfall of over 1000 millimeters and semi shaded and semi sunny conditions. It is best grown in subtropical deep mountain forests with an average temperature of over 8 ℃ in January. The suitable growth temperature is 15 to 28 degrees Celsius, and the suitable air humidity is above 60%. It does not have strict requirements for soil and fertilizer. In the wild, it mostly grows on loose and thick bark or trunk, and some also grow in crevices. Belonging to the aerial root system, it mainly requires good permeability of the roots, and the substrate used should be well ventilated, breathable, and filter water. Under suitable temperature and humidity conditions, the growth rate is fast and the survival ability is very strong. At the end of spring and beginning of summer every year, flower clusters emerge from the upper nodes of biennial stems. After flowering, new shoots grow from the stem base and develop into stems. In autumn and winter, they enter a dormant period.
The stem is upright or slanting, usually about 20 centimeters long, 7-10 millimeters thick, unbranched, with several nodes; The internodes are flattened or rod-shaped, measuring 3-3.5 centimeters in length, and the base often contains paper leaf sheaths. Leaves are leathery, alternate in the upper part of the stem, lanceolate, 5.5-8 cm long, 1.3-2 cm wide, slightly blunt at the tip and with unequal sides and two slits, and have a sheath that embraces the stem at the base; The inflorescence usually emerges from the upper part of an old stem with fallen leaves and has two flowers; The inflorescence stalk is 6-16 centimeters long, and the base is covered with a membranous sheath about 5 millimeters long
Bracts membranous, ovate triangular, approximately 6 millimeters long; The flower stem and ovary are light rose colored, measuring 5-6 centimeters in length; Flower white with rose colored tip, spreading out; The middle calyx is round lanceolate in shape, measuring 3.5-3.7 cm in length and 9 mm in width, with a nearly blunt apex and 5 veins; The lateral sepals are ovate lanceolate, measuring 3.5-3.7 cm in length and 9 mm in width, with a nearly acute apex and 5 veins; The calyx sac is nearly cylindrical, measuring 5 millimeters in length; Petals are broadly oblong, measuring 3.5-3.7 cm in length and 1.8 cm in width. The apex is acute and pointed, and the base is slightly narrowed into short claws, with 5 veins; Lips nearly circular, concave, about 2.4 cm wide, apex acute with rose color, base with purple red stripes on both sides; The center of the lip disc is golden yellow, densely covered with short hairs; The front surface of the stamen has purple red stripes, about 8 millimeters long; The medicine cap is white with a rounded and blunt tip.
