Mindanao, Zamboanga, San Ramon, 800 m. s. m., Copeland 1710. 



This Diplazium is in the group of D. latifolium (Don) Moore. The form of 

 the frond and of the sori suggest D. vestitum Presl, but the rachises are without 

 the characteristic pubescence. Young plants with fronds still simply pinnate 

 are sometimes fertile.
