Planta Lindheimeriarue. 143 



by Moricand, from flowering specimens which occurred in 

 Berlandier's Texan Collection. We have now fine specimens 

 both in flower and fruit from Mr. Lindheimer's, Mr. Wright's, 

 and from Dr. Gregg's collections ; the latter met with it as 

 far south as Buena Vista. I have characterized it as a third 

 section of Berberis, in the Genera Am. Bor.-Gr. lllustrata, 1. 

 p. 80.

323. Streptanthus petiolaris, Gray, PL Fendl. p. 7. 

 Muskit thickets and shady woods, New Braunfels and San 

 Antonio. March. — All the lower leaves, as well as the base 

 of the stem, are more hairy in my specimen than in those 

 cultivated in the Cambridge Botanic Garden, from seeds 

 taken from Mr. Wright's plant ; and the radical leaves are 

 barely lyrate-pinnatifid, and rounded at the summit. From 

 seeds sown in early spring, it flowers and fruits during the 

 summer and autumn. 



f S. bracteatus (Gray, Gen. Am. Bor.-Or. 111. 1. p. 146, 

 t. 60. fig. 1-3.): glaberrimus, subglaucus ; foliis caulinis 

 auriculato-amplexicaulibus, inferioribus oblongis acutis ssepe 

 repando-dentatis, superioribus cordatis sinu profundo clauso 

 in bracteas cordatas (inferiores florem, summas pedicellum 

 subaequantes) sensim decrescentibus ; petalis obovatis purpu- 

 reis ; siliquis angustis praelongis (5^-6 unc.) patentibus sub- 

 falcatis. — At New Braunfels. June. Also gathered by 

 Mr. Wright on sand bars of the Colorado, near Austin, in 

 flower only, in the month of April. The radical leaves are 

 sometimes entire or barely repand-toothed, sometimes incised 

 or even lyrately pinnatisect, with most of the lower segments 

 minute. One of Mr. Wright's specimens is remarkable for 

 having all the lower cauline leaves pinnately parted in this 

 way, and petioled. The sepals are tinged with deep purple ; 

 the petals are light purple, with the broad spreading lamina 

 half an inch in length. No ripe pods were gathered. The 

 largest seen are about six inches long, but less than a line 

 wide ; the immature seeds are winged. I have no specimens
