Sp. incisum, Pr.; pulveruleutum, Z.; serrulatum, Z/«w.; villosum, 

 Linn. ; variura, H. B. K. ; falcatum, Sw. ; obtusum, Desv. ; hirtum, 

 Kl.; Cayennense {Willd.), Klotzsch; Klotzschianum, //(9oA-. = tomen- 

 tosum, Klotzsch, the name being changed because inappropriate, a 

 liberty we believe few botanists will entirely approve ; prionophyllum, 

 H. B. K. ; rhomboideum, H. B. K. ; laxura, Kze. ; Haenkeanum, Pr.; 

 fructuosum, Spr. ; urophyllum, Hook., a new species, from the Pa- 

 cific coast of South America, — it may be remarked that the specific 

 character as well as figure in this instance appear to agree very well 

 with the ordinary form of prionophyllum, a native of the Atlantic 

 coast of the same continent ; intermedium, Sw. ; glaucescens, Kl. ; 

 triangulatum, Kaulf. ; denticulatum, Sw. ; proximum, Gaudich. ;

Sp. Le Prieurii, Hook., a new species, collected in Berbice, by Sir 

 R. H. Schomburgk, and on moist declivities of the mountain Matouri, 

 at Notaille and Oyapoch, French Guiana, by Le Prieur. This appa- 

 rently distinct species does not range well with its neighbours. Is it 

 an Adiantum ? 



[Indistinctly pedate). 



Sp. affine, Willd., a curious instance of the fallacy of a nan?e, this 

 species having no kind of similarity to the preceding or following.
