 chaud. (Bulletin of the Torrey Botanical Club. XXXII. No- 

 vember 1905. p. 587—596.) 



A preliminary revision of Alciconiiinn, a genus of tropical ferns, 

 established byGaudichaud in 1826, this name having clear pri- 

 ority over the accepted name Platycerium Desvaux, 1827. The 

 complicated nomenclatorial history of several of the species is 

 traced in detail and the synonymy of each is given, together with 

 references to all published illustrations. Thirteen valid species are 

 recognized, as follows: Alciconiinm Andimim (Baker) Underw., this 

 being the only American species known; A. angolen&e (Welw.) 

 Underw., A. bifiircatum (Cav.) Underw., A. coronarinm (Müller) 

 Underw., A. Elllsil (Baker) Underw., A. grande (J. Sm.) Underw., 

 A. Hillii (Moore) Underw., A. madagascariense (Baker) Underw., 

 A. Stemmaria (Beauv.) Underw., A. sumbawense (Christ.) Underw., 

 A. Wallichu (Hook.) Underw., A. Willinckii (Moore) Underw., and 

 A. Veitchii Underw., the last a new species from Adelaide, 

 Australia, which, though previously mentioned in literature several 

 times, is here first published. Maxon.
