Nota. Descriptio plantae, quae a cl. N. E. Brown in Journ. Linn. Soc. XVIII. (4 880) 

 250 false ad A. heterophyllum Blume attribuitur, exacte cum notis hujus speciei congruit. L. c. 

 p. 250 dicitur: »The pedatisect leaf has 15 — 17 sessile, oblong-lanceolate, shortly cuspidate Seg- 

 ments, the middle one being about as long as the first pair of lateral ones.< 

 Contradictio autem 1. c. p. 251: »From both of these [A. tortuosum Schott et A. curvatum Kunth) 

 and from all others of the group at present known it is readily distinguished by the middle 

 leaflet being shorter than the lateral ones next it«.
