Paphiopedilum markianum Fowlie in Orch. Dig. 54 (3) : 125. 1990; Z. H. Tsi, S. C. Chen et K. Mori, Wild Orch. China 28. pl. 22. 1997;中国兰花全书123.图6-4 (1) . 彩图6-18. 1998. ——Paphiopedilum tigrinum Koopowitz et Hasegawa in Orch. Advocate 16 (3) : 78. fig. 1. 1990.
Shaded and rocky places in forests or thicket margins along valleys; 1400-2200 m. SE and W Yunnan (Lushui, Malipo) [NE Myanmar]. Markianum and P.tigrinum were both published in 1990. The former was from July to September, and the latter was from May to June. However, because the official print of the former was sent to important academic institutions in the United States and Germany on May 24, while the latter did not specify the type specimen collector, number and date, the former was used ( see Orchid Dig. Apr.-June : 58-61.1991 ). |
