Plantce Lindheimeriajice. 161 



351. Malvastrum carpinifolium, Gray, PL Fendl. p. 22. 

 In sterile soil, New Braunfels, &c. August. — To the syno- 

 nyms cited in the work above-cited, I have to add that of 

 Malva Lindheimeriana, Scheele in Linnaa, 21, (1848,) p. 

 470. The flowers open merely during a few hours of the 

 brightest sunshine. 



352. Pavonia Wrightii, Gray, Gen. III. 2, p. 76, t. 130. 

 P. lasiopetala, Scheele in Linnaa, 21, p. 470. Rocky soil in 

 Cedar woods, New Braunfels. Also gathered in Western 

 Texas, by Mr. Wright, and near Monterey, in Northern 

 Mexico, by Dr. Edwards and Major Eaton. — A low, shrubby 

 species, with handsome, rose-colored flowers, which are larger 

 in the wild than in our cultivated plant, from which the figure 

 in the Genera Illustrata was made. The seeds are glabrous, 

 except a little pubescence at the chalaza ; and in some other 

 respects, also, the species is not very well characterized by 

 Scheele. His name, from its priority in publication, should 

 probably be adopted, although so badly chosen ; for the petals, 

 at most sparingly stellate-pubescent externally, are often 

 nearly or quite glabrous. 



353. A. Texense (Torr. fy Gray, Fl. 1, p. 231): tomento 

 minuto molli undique velutino-canescens ; caule (2-4-pedali) 

 paniculato; foliis cordatis acutis vel subacuminatis serratis 

 supra viridulis, ramealibus gradatim minoribus ; pedunculis 

 inferioribus petiolum subsequantibus, summis folio longiori- 

 bus ; corolla lutea ; capsula ovoidea obtusa cinerea 8-loculari 

 apice breviter 8-loba calyce 5-fido demum reflexo multum 

 longiore ; carpellis erectis obtusiusculis muticis 3-spermis. 

 — Prairies, &c. in hard and dry soil, New Braunfels. August, 

 September. Apparently common throughout Texas, and to 

 Monterey, in Northern Mexico, where it was gathered by Dr. 



brevi complanato membranaceo iuflexis. — On the Rio Grande, Texas, in dry soil. 

 Cultivated in the Cambridge Botanic Garden, it flowers through the summer. Stems 

 a foot or less in height, much more slender than in M. coccineum ; the flowers smaller 

 and paler (between a buff and a brick-color.) The leaves are not canescent, but green 

 and sparsely stellate-hirsute, and their segments incised or almost pinnatifid ; the lobes 

 are tipped with a deciduous mucro or short seta.
