Hort. Bog. (? Malesia). — The description of' this splendid 

 and interesting fern is taken from a specimen propably gathered 

 in one of the malayan islands and since many years cultivated 

 in the Buitenzorg gardens. — I give this as a uew species with 

 some hesitation the diagnose of one of the austialian species 

 (P. Veitchii. G. Ghr.) being unknown to me. — If Underwood's 

 conception of the priority of the generic name should be right this 

 species should be called Alcicornium Wühelminae Eeginae, v. A.

 The Netherlands. — Raciborski referred this plant to P. grande, 

 J. Sm.
