 Roemeriana, Scheele iiiLinnaa, 21, p. 583, would seem to be 



cultivated specimens, the silicles are considerably larger. The stipe is sometimes 

 almost as long as the pod; sometimes scarcely half that length. 



10. V. Goedoni (sp. nov.) : tomentuloso-canescens ; caulibus difl'usis ; foliis sub- 

 iniegerrimis, infimis subspathulatis, superioribus lanceolatis vel linearibus ; racemo 

 fn ctifero laxo; pedicellis brevibus patentibus ; silicula glabra breviter stipitata stylo 

 subduplo longiore. — On the Canadian, in the Katon Mountains, Mr. Gordon, 

 (communicated by Dr Engelmann.) April; in flower and fruit. — This is, perhaps, a 

 perennial species, but the root appears more like that of a biennial. The plant is sil- 

 very-hoary, with a stellate pubescence; except the pods, which are very smooth, and 

 two lines in diameter. Flowers not larger than those of V. gracilis, more crowded. 

 The unripe seeds are not at all margined.

 ji. pallida, Torr. if- Gr. 1. c. p. 101. — The corolla is said, by Dr. Leavenworth (who 

 alone has met with this plant) to be " white."

16. V. stenophylla (sp. nov.) : humilis, cano-argentea, multiceps ; foliis anguste 

 linearibus gracilibus confertis; racemo multifloro denso; silicula membranacea gla- 

 berrima stylum sequante. — On the Rio Grande, Texas, Mr. Charles Wright. Mon- 

 terey and Aguaneuva, Northern Mexico, Dr. Gregg, Dr. Edwards. — The specimen 

 of Mr. Wright is the most characteristic one. From a thick, ligneous caudex it bears 

 several, more or less woody branches, a span high, densely leafy, and terminated by a 

 very compact raceme of golden yellow flowers, nearly as large as these of V.grandi- 

 jiora. The plants of Gregg and Edwards are less condensed, and with smaller flow- 

 ers. The leaves are an inch or more, the lower over two inches in length, entire, or 

 the lower sparingly toothed ; and the pods, also, are twice the size of those of V. 

 Fendleri. Specimens intermediate between the two may perhaps occur.
