Neobathiea grandidierana is a species of orchid from Madagascar and the Comoros. It is named after the French naturalist Alfred Grandidier, who devoted his life to the study of Madagascar. Among the 6 described species of Neobathiea, this species is the most widely distributed within Madagascar, occurring in Antsiranana, Antananarivo, Fianarantsoa, and Toliara.[1] In the Comoros, it occurs in Anjouan and Grande Comore.[2] The habitat of this species is humid forest on west-faching slopes at the elevation range of 1000-1650m.[2] In nature, the flowering season of this species is spring to early summer.[1]
The long-spurred Neobathiea grandidierana from Madagascar is pollinated by a long-tongued sphinginid hawkmoth Panogena lingens with the pollinaria deposited on the basal part of the proboscis of the moth.[3]
