Anisosoriis Trevis. Atti dell' Ist. Veneto II. 2: 166. 1851. 



Type: Pteris laciniata Willd. , and thus synonymous with 

 Antiosorus Römer, Kuhn 1882. 



Neurosorus Trevis. Atti dell' 1st. Veneto II. 2: 168. 1851. 



Types : Grammitis caudata Wall, and Gymnogramme javanica 

 Bl. ; thus synonymous with (if not older than) Coniogramme 

 Fée 1850—52. 



Eschatogramme Trevis. Atti dell' 1st. Veneto II. 2: 168. 1851. 



Types: Pteris furcata L. and Taenitis Desvauxii Kl. This 

 name is surely the best generic one for the named species, as 

 the following list of synonyms shows. 

 Eschatogram m e furcata (L). 



Pteris L. 1753; Taenitis Willd. 1810; Pteropsis Desv. 1827; 

 Cuspidaria Fée 1850 — : 52 (not Cuspidaria DC. 1821); Dicrano- 

 glossum J. Sm. 1854; Taeniopsis Moore 1857; Vittaria Baker 

 1870; Elaphoglossum Keyserling 1873; Oetosis O. Ktze. 1891. 



Mildella Trevis. Rendic. Ist. Lombardo sei. et lett. II. 9 : 807. 1876. 

 Type; Pellaea intramarginalis (Klf.) J. Sm. 



Cheilosoria Trevis. Atti dell' 1st. Veneto V. 3:579. 1877. 

 Type: Cheilanthes tenuifolia Sw. 



Eremopodium Trevis. Atti dell' 1st. Veneto V. 3 : 589. 1877. 



Types: Asplenium viitæforme Gav. and A. sundense Bl. The 

 genus falls under, but it is not identical with Micropodium Mett. 



I take here the opportunity to state, that the first fascicle of 

 the important work, Reliquiae Haenkeanæ, containing the Filices 

 by Presl, was edited 1825, not 1830 as Underwood and several 

 others think, and thus antedates Desvaux: Prodrome, Blume's 

 Enumeratio and other books on ferns ; this mistake has caused 

 very great confusion in the nomenclature. 



The genus Leptochilus in my sense is mainly an old-world's 

 genus and exclusively tropical. Out of about half a hundred 

 described species only about a dozen are restricted to tropical 

 America, but here widely spread from the West-Indies and Mexico 

 to Paraguay and southern Brazil. The majority of the American 

 species belong to the genus Bolbitis Schott (Poecilopteris Pr. ; Cyrto- 

 gonium J. Sm. ; Heteroneuron Fée), the others, viz. : L. alienus (Sw), 

 L. Fendleri (Eat.), L. nicotianifolius (Sw.), L. oligarchicus (Bak.)
