 Ultimate segments! subspreading, lineal', entire, close or + distant, to i^cM. long, 

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

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

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

 Specimens in the Buitenzorg herbarium have the fronds vyith the axillary 

 buds copiously developed and without stipulae^ as in Protogleichenia.
