Colletogyne
Colletogyne is a monotypic genus of flowering plants in the Araceae family. The single species making up the genus is Colletogyne perrieri. Colletogyne is endemic to northern Madagascar and is found growing in only one small region abundant with limestone. Much like the other genera in Araceae found exclusively in Madagascar Colletogyne is believed to be one of the most advanced aroids with regards to its flowers and pollen structure. Colletogyne has heart shaped leaves and is tuberous. The spathe is white with purple spots and the spadix has red spots. It is often found growing in humus in and amongst limestone.
