Cheirostylis thailandica is characterized by its petals with recurved tips and non-adnate to dorsal sepal , two green spots at the base of epichile, non-fringed lobules and stylids slightly longer than rostellum arms . Listera brevicaulis differs from all its allies by having very short stem with its leaves prostrate on the ground , bilobed lip with its lobelets recurved and meeting underneath. Pholidota recurva is characterized by its cylindrical and superposed internodes, secund
