The following pages contain descriptions of some new species 

 of ferns and fern-allies and complétions of older, well-known 

 diagnoses. 



For the sake of convenience the gênera hâve heen arrangea al-

Paraphyses obconico-pyramidatae, apice truncatae, obtuse 

 3 — B-lobatae. 



This form, determined as A. callifolium Bl, differs from the 

 type in having the paraphyses obconical, rather 3 — 6-angularly 

 obpyramidal, i. e. narrowed at the base, dilated, truncate and 

 sinuated at the apex with 3 — 6 rounded lobes and impressed 

 sides ; costa pale, indistinct except at the very base. — New Guinea 

 (Versteeg No. 1153). 



The type has the paraphyses pyriform, entirely smooth, and 

 rounded at'the apex. 



A. callifolium BL differs from the preceding forms in having 

 the paraphyses perfectly linear, not thickened at the apex. 



The new variety bears the name of Mrs. M. Lang, Assistant 

 at the Buitenzorg Herbarium, who observed me the erroneous 

 détermination quoted above.
