 hairs; stipe 10 cm. liij^li. firm, erect, pubescent; frond 30 to 4.5 cm. I«mg,

 the central ones the largest, 10 cm. or more long, 2 to 4 cm. broad, cut 

 down to a broadly winged rachis, with oblong pinnules cut about half 

 way down with faleatr, nnuronate teeth: texture thinly herbaceous,

Warburg's Davao plant is described as epiphytic. The Mariveles speci- 

 mens are terrestrial, witli rliizomes so short the fronds are clustered.
