Plante Lindheimeriane. 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.- Ór. Illustrata, 1.

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. 
T S. pracreatus (Gray, Gen. Am. Bor.-Or. Ill. 1. p. 146, 
t. 60. fig. 1—3.): glaberrimus, subglaucus; foliis caulinis 
auriculato-amplexicaulibus, inferiotibus oblongis acutis sspe 
repando-dentatis, superioribus cordatis sinu profundo clauso 
in bracteas cordatas (inferiores florem, summas pedicellum 
subzequantes) sensim decrescentibus ; petalis obovatis purpu- 
reis; siliquis angustis preelongis (54-6 unc.) patentibus sub- 
faleatis. —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
