Description
Type:— JAPAN. Ryukyu Islands: Kagoshima Pref., Amami-Oshima Island, Amami City, Naze, 5 May 2018, Morita N 15-04 (holotype: TNS, a flower in the spirit collection).
Didymoplexis siamensis var. amamiana differs from D. siamensis var. siamensis only in lacking a pair of the long recurved stelidia on each side of its stigma.
Additional specimens examined:— JAPAN. Ryukyu Islands: Kagoshima Pref., Amami-Oshima Island, Amami City, Naze, 5 May 2018, Morita N15-07 (TNS, a flower in the spirit collection); Kagoshima Pref., Amami-Oshima Island, Amami City, 13 May 2018, Morita N15 - A (KYO, a flower in the spirit collection).
Note:— The new variety is currently known only from a single population. About 20 flowering individuals were found in a dense forest dominated by Castanopsis sieboldii (Makino) Hatusima (1971: 223). The new variety is not completely sympatric with D. siamensis var. siamensis, whereas D. siamensis var. siamensis can be observed a few hundred meters from the type locality.
