Stems 3-6 inches high. Leaves 1 - Iw inch in diameter, sometimes sprinkled with a 

 few very short hairs on the upper surface, flat. Peduncles longer than the leaves. Flowers 

 as large as in the preceding species, pale blue ; the petals veined with deep purple. Spur 

 slender, sometimes nearly twice the length of the flower. Appendages of the anthers filiform, 

 extending almost the entire length of the spur. Style slender, of nearly uniform thickness 

 throughout, terminating in the tubular stigma, the orifice of which is manifest, as in V. Muh- 

 lenbergii. 



Swamps and moist rocky woods. Latter part of May. Rather common in the interior 

 of the State, but not yet found below Hudson. Fl. Latter part of May and early in June. — 

 The whole appearance of the plant, except the long spur, is that of V. MuJilenbergii ; but the 

 characters given above seem to be pretty constant. 



§ 2. Stigma capitate, bearing a tuft of hairs on each side, with a minute somewhat lateral orifice : 

 style compressed, clavate : stamens oblong, approximate ; torus rather flat : capsule often triangular.
