In Mededeel. Rijksherb., No. 31, p. 7, Rosenstock, citing Zollinger's 

 No. 1602 but not mentioning any source and without any discussion or 

 explanation, reduced ihis species to Dryopteris vilis O. Ktze=:Aspidium 

 vile Kze. 



We possess in the Buitenzorg Herbarium neither the typespecimensof Zol- 

 linger nor those of Blume so that I am not able to make any comparisons 

 but those plants to which the exisiing diagnoses are fitting show the way. 



Besides the original diagnosis of A. vile Kze (in Bot. Zeit. , 1846, 

 474) there exists another one (with citation of the same number 1602) 

 by Mettenius, in Farng. , IV, Phegop. & Aspid. , 114, 



When coniparing thèse two diagnoses it appears that, whilst agreeiiig 

 in some respcts, they differ in other points. Kunze says f. i. „soris . . . 

 inter costulas strigoso-paleaceas et marginem revolutum mediis, e furcatione 

 venarum oriundis; indusiis medio pilosis. fugacibus; etc." — In the parallel 

 part of the description by Mettenius we read „laciniae . . , nervum 

 ramis indivisis ... ; sori costulis potius quani margini approximati 

 . . . . ; indusium minutum, membranaceum, margine longissime araneose 

 ciliatum" . 



Given the existence of so mportant discrepancies in essential parts we 

 may ask whether ZoUinger (as has repeatedly happened and still happens)
