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.
A new species of the genus Alpinia subgenus Alpinia subsection Catimbium (Zingiberaceae), A. nelumboides is described from Laos and Vietnam. It is morphologically most similar to A. kwangsiensis, but distinguished by its large pinkish bracteoles, shorter petioles, entire margin of labellum, and larger pubescent ovoid fruits.
