[Ventenat declares, after Jussieii, that Viola is the type of a 

 natural order, jjreswned to exist, but of" which no other 

 genus is known. It were better to say it cannot be referred 

 to any known order ; for though it possesses here and 

 there a character of several different orders, it is hardly 

 allied, on the whole to any one.] 



Cat. inferior, permanent, of 5 ovate-oblong, erect, equal, 

 acute leaves, inserted above their obtuse base ; 2 of them 

 subtending the uppermost petal; one each of the lateral 

 petals ; and one the 2 lowermost. Cor. irregular, of 5 un- 

 equal petals ; the uppermost solitary, broadest, most ob- 

 tuse, slightly cloven, directed downward (the position of 

 the flower being reversed), terminating at the base in a 

 horn-shaped blunt nectary, projecting betwixt the calyx- 

 leaves ; 2 lateral petals opposite, equal, obtuse, straight ; 

 2 lowermost (turned upward) equal, larger. Filam. very 

 small, 2 of which, adjoining the odd petal, have 2 com- 

 bined spurs, which enter the nectary. Anth. broad, con- 

 verging, scarcely connected, obtuse, each terminating in 

 a membranous point. Germ, superior, roundish. Style 

 thread-shaped, projecting be^^ond the anthers. Stigina 

 oblique, pointed or concave. Caps, ovate, triangular, ob- 

 tuse, of 1 cell and 3 rigid, finally reflexed, valves. Seeds 

 several in each cell, ovate, polished, attached to the linear 

 central receptacle of each valve. 



The stigma of V. odorata, and its allies, is a simple liooked 

 point ; in V. tricolor, and others of the Pansy tribe, it is 

 a hollow knob, perforated at the summit, and gaping oc- 

 casionally. T^hejlower is reversed, or inverted, in all the 

 Europajan species ; in most of the Indian ones erect. 



The species are numerous, almost entirely herbaceous, and 

 of humble stature. Stem trailing, or erect, or wanting. 

 Leaves stalked, simple, mostly alternate; in some instances 

 deeply divided; in ail crenate, or serrated. Stipidas in 

 pairs, various and remarkable. Fl. on simple stalks, va^ 

 riously coloured ; very often streaked in a radiant man- 

 ner, like Veronica. One species especially is highly fra- 

 grant, and gives its name to a peculiar deep purplish-blue
