in Hook. Jonm. Bot, 3 (1841) 411. 
A reduced insular form of the D. glandulosa type. The plant small, the 
terminal pinna only developed, the lateral ones reduced to auricles. 
Leyte (315 Cuming), This is the plant figured by Hooker Sp. Fil. 1: 19. A 
sterile frond with the above specimen shows that it is a larger plant than 
figured and demonstrates clearly that the species is more especially a reduction 
of D. Spenceri. Specimens from San Ramon, JIiadanao {Copeland) February, 
April, 1905, have the nerves less pronounced, the terminal pinna narrower and 
the pubescence more grayish.
