Ravenea moorei J.Dransf. & N.W.Uhl

This species is accepted, and its native range is Comoros (Njazidja).

Comoro Islands: Grande Comore.
Secondary moist forest; 500-800 m.
Endangered. Seed of this species was collected by DeArmand Hull in October 1993 at the north end of Grand Comore at c. 500 m, above Mitsamouli; only two female trees were seen by Mr. Hull. He considers them highly endangered due to continuing agricultural pressure on the forest in this area.
