Apetalse by Samydeae,* and on the other, though as it seems to me less 

 intimately, with Polypetalas by Violese, would not accord with any arrange- 

 ment of natural orders that has yet been given. While the admission of the 

 floral envelope being entii-ely calyx ; and of the affinity of the class with Violese, 

 would certainly be unfavourable to M. de CandoUe's ingenious hypothesis of 

 petals in all cases being modified stamina. 



VIOLEjE.f Tliis order does not appear to me so nearly related to Passi- 

 floreje as M. du Petit Thouars is disposed to consider it : for it not only has 

 a genuine polj-petalous corolla, which is hj'pogynous, but its antheras differ 

 materially in structure, and its simple calyx is divided to the base. The 

 irregularity both of petals and stamina in the original genera of the order, 

 namely, Viola, Pombaha,|:J; and Hybanthus, though characters of considerable 

 importance, are not in all cases connected witli such a difference in habit as to 

 prevent their union -nith certain regular flowered genera, which it has lately 

 been proposed to associate with them. 



The collection from Congo contains two plants belonging to the section of 

 Violeffi with regulai- flowers. One of these evidently belongs to Pussalia, an 

 unpublished genus in Sir Joseph Banks's herbarium, and described in the manu- 

 scripts of Solander from a plant found by Smeathman at Sierra Leone, which is 

 perhaps not specifically distinct from that of Congo, or from Ceranthera dentata 

 of the Flore d'Oware. But Ceranthera,% wliich ]\I. de Beauvois, being unac- 

 quainted with its fruit, has placed in the order Mehaceae, is not difierent from 

 Akodeia, a genus published somewhat earlier, and from more perfect materials, 

 by M. du Petit Thouars,H who refers it to Violeae. 'llie latter generic name 

 ought of course to be adopted, and with a change in the termination (Alsodince) 

 it may also denote the section of this order with regidar flowers. 



Physiphora of Sir Joseph Banks's herbarium, discovered by himself in 

 Brazil, differs from Alsodeia only in its filaments being very slightly connected 

 at base, and in the form and texture of its capsule, which is membranaceous, 

 and, as the name imports, inflated.
