Main Article Content
Platycerium grande (Fee) Kunze is an endemic, Critically Endangered species of fern in the Philippines. The known distribution of this species remains limited at present and its population is threatened by various anthropogenic threats especially for ornamental collection. In our recent survey, we found high abundance of this species in Central Mindanao, southern Philippines. It can be distinguished from other species belonging to the genus Platycerium through its frond’s vegetative leaf which is symmetrical with two equally long main lobe. Based on literatures, the known distribution range extend from Zambaonga, Lanao, and Davao (Mt. Apo); and our recent records extends the known distribution of this species in Kalamansig, Sultan Kudarat and South Upi, Maguindanao suggesting this species may still be around in other areas within the known range, however, the species may remain narrowly distributed as multiple threats to this species continue to persist.
