A new locality of Lecanorchis taiwaniana from Nam Ha National Protected Area, Luang Namtha Province, northern Laos is reported and a description of the species based on the Laos material is provided. Lecanorchis taiwaniana was known previously only from Japan and Taiwan. Considering that species of Lecanorchis are easily overlooked in the wild due to their short flowering season and dwarf habit, it is possible that L. taiwaniana is more widely distributed.

Gastrodia albida T. C. Hsu & C. M. Kuo is reported from Yaku Island, Kagoshima Prefecture, Japan, as a new record of this species to Japan. Traits of G. albida are described and illustrated based on specimens collected on Yaku Island. This species has a unique combination of characters, such as only partly united lateral sepals, curved perianth tube and white triangular lip. The population on Yaku Island differs from the population at the type locality in Taiwan in having widely opening lateral sepals and a flat-topped disk of the lip and epichile slightly 2-ridged along the margin.
