 as is said by Don, but has a midnerve stretching from the apex towards the base, 

 as is usual in the genus.

5. V. Shortii, Torr. tf« Gr. Fl. 1. p. 102. — The silicles, in the specimen of Herb. 

 Torr., the only one I have ever seen, are nearly all sterile and imperfectly grown ; 

 hence their small size in proportion to the length of the style. In one pod, however, 

 although remarkably small for the genus, I found a single ripe (marginless) seed, 

 nearly filling the cell ; in this case the style was no longer than the silicle. The 

 species, although not suthciently well known, is unlike any other here enumerated.

 There are no specimens with full-grown silicles, while those of V. Nuttallii are alto- 

 gether fruitful, with no good flowers. There is much reason to suspect that the two 

 belong to one species. V. Nuttallii usually has a shorter but distinct stipe to the 

 pod ; but in one of the original specimens the stipe is fully as long as in V. gracilis.
