Description
Colletogyne has heart shaped leaves and is tuberous. The spathe is white with purple spots and the spadix has red spots. 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.
Range and habitat
Colletogyne is found only in the Montagne des Français protected area in the dry deciduous forests of northern Madagascar, where it grows in shrubland on limestone substrate between 100 and 300 meters elevation.[1]
It has a small range, and is threatened with habitat loss from deforestation. Its conservation status is assessed as vulnerable.[1]
