PLANTS OF WHICH THE SITUATION IS UN- 

 CERTAIN. 



1. PARNASSIA. 



Cal. 5-parted, persistent. Pet. 5, hypogynous, alternate with

 with a hole between them. (Juss.) Capsule 1- celled, 4-val-

 dle. Seeds very numerous, winged on one side, attached to 

 the margin of the dissepiments. Albumen none. Embryo 

 cylindrical. Cotyledons very short, obtuse. Radicle long, 

 straight, centrifugal. (GcBr'tn.)

It is much to be regretted, that so beautiful a plant as this should 

 have no certain station assigned it in any natural arrangement ; and 

 the more so because its structure is completely understood. Probably 

 it is, as Ventenat has supposed, one of those genera which constitute 

 distinct orders of themselves ; just as many solitary species constitute 

 distinct genera. M. de Jussieu, in his Genera Plantarum, placed it 

 next Drosera and Reseda, among the genera supposed to be akin to 

 Capparides. Adanson arranged it among his Cisti. Sir James Smith 

 has conjectured it might be related to Saxifraga and Dioncea; and we 

 believe Mr. Brown is disposed to favour the opinion of its affinity to 

 the former enus. There are others who consider it more near Hy?
