SCItOPIIULAKIACEvE. 153 



This species bears a general resemblance to the preceding, but 

 is a much stouter plant. The leaves sometimes are more than an 

 inch long, broader, with the teeth larger and more acute ; peduncles 

 much longer ; flowers about \ inch across, brilliant blue, with 

 darker veins ; the 2 pairs of sepals widely divergent. The capsule 

 is larger and much more compressed than in the two preceding 

 species ; the lobes gradually attenuated into the sharp keel, with 

 the notch between theni forming a very obtuse angle ; the surface 

 nearly glabrous, except at the top, and with a very evident network 

 of raised lines. Plant green. 



It is probable that the name V. Persica ought to be adopted ; 

 but the plant so named is described by Poiret as having the pedun- 

 cles shorter than the leaves, and the corolla-segments shorter than 

 the calyx.

Annual or perennial. Flowers in terminial racemes. Pedicels 

 not reflcxed in fruit, solitary in the axils of bracts, which towards 

 the top of the stem become much smaller than and dissimilar to 

 the lower leaves. Corolla 4-partite ; tube of the corolla shorter 

 than wide. Seeds flat or plano-convex, scarcely excavated beneath 

 in any of the British species except V. triphyllos.

Annual. Stem stiff, decumbent at the base, then ascending or 

 erect, usually slightly branched ; branches ascending. Lowest 

 leaves stalked, ovate, entire or toothed ; middle and upper ones 

 sessile, palmately-partite, with 3 to 5 oblong or obovate entire 

 segments. Bracts alternate, sessile, tripartite, or the uppermost 

 ones entire, the lowest sometimes with the lateral lobes cleft. 

 Flowers in a lax raceme. Peduncles longer than the bracts and 

 calyx, curved upwards. Sepals oblong, obtuse, clothed and ciliated 

 with gland-tipped hairs. Capsule orbicular, rather shorter than 

 the calyx, obcordate, much compressed above, faintly veined, 

 ciliated with gland-tipped hairs ; the lobes contiguous, separated 

 by a deep acute-angled or right-angled sinus between them. Style 

 projecting beyond the notch of the capsule. Seeds excavated on
