ßl.) doubtfully referred by me to H. pusilla Carr.; two of these are sterile, 

 and undeterminable but positively distinct from the 3rd (Hallier No. 3317), 

 which may be Copeland's H. pusilloides. At any rate the latter, as well as 

 Kornassi's No. 735 from Ceram {Makoeala Ina, L. Rutten's Explor. Com- 

 miss.), fits nearly Copeland's key of Bornean ferns and is distinguished by 

 the following characters: 



Rhizoma longe repens, in sicco brunneum, albido-pruinosum, squamis 

 brunneis, subulato-lanceolatis, erectis, decidue vestitum. Sîipites sparsi, 

 frondium steriliuin V4 — 1 cm., fertilium 1 — 4 cm. longi, glabri vel parce 

 squamulosi. Frondes rigide coriaceae, glabrae. Frondes steriles late cordato- 

 ovatae, i 1 — 2 cm. longae et latae, apice obtuso parce flabellato-lobatae, 

 basi profunde pinnatipartitae ; segmenta primaria conferta vel approximata, 

 usque ad 4 in utroque latere, superiora ascendentia, sublineari-oblonga, 

 obtusa, inferiora horizontalia, postice producta, frondium minimarum antice 

 integerrima vel subintegerrima, postice lobata ad pinnatifida, frondium 

 maximarum antice pinnatifida, postice profunde pinnatipartita, segmentis
