Hort. Bog. {? Malesia). - The description of this splendid 

 and interesting fern is taken from a spécimen propably gathered 

 in one of the malayan islands and since many years cultivated 

 in the Buitenzorg gardens. ■ I give this as a new species with 

 some hésitation the diagnose of one of the austraîian species 

 (P. Veitchh, 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 Wilhelminae Reginae, v. A. 

 v. R. It is dedicated to Her Majesty WILHELMINA, Queen of 

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

 J. Sm.
