* (13) O. hispida, Mett., Rac, Flor. Btz., I, 12. 



Fronds to ± 50 c.M. long, forked. Forkings 1 — 3 X forked again. 

 Ultimate segments erecto-patent, lineai', entire, close or + distant, to 2 c.M. long, 

 ± 2 m.M. broad, the edges recurved. Texture coriaceous; stipes, rachises and 

 under surface more or less densely covered with a tomentum of long, ferru- 

 gineous hairs, the younger portions of the fronds very densely tomentose. — 

 Specimens in the Buitenzorg herbarium have the fronds with the axillary 

 buds copiously developed and without stipulae, as in Protogleichenia.
