Britton and Shafer, N. Am. Trees 358. fig. ji8. 1908; Mackensen, 

 Trees and Shrubs of San Antonio, 17. pi. j. 1909. — Koch's descrip- 

 tion of C. Lindheimerii was made from a tree growing in the Botanic 

 Garden in Berhn which had been raised from seeds gathered at 

 New Braunfels, Texas, by Lindheimer and sent by Engelmann 

 to Berhn. Koch's description leaves no doubt that C. Lindheimerii 

 (Engelmann in Herb. A. Braun) is the tree with leaves pale and 

 densely pubescent on the lower surface and pubescent branchlets 

 which is common at New Braunfels and in the neighborhood of 

 San Antonio. 



Of the specimens of this tree which I have seen the oldest was collected 

 by Drummond in 1834 without locality but probably near Austin (nos. 343 ?, 

 334, 259 in Herb. Gray). It was collected by Lindheimer at New Braunfels, 

 Comal County, in 1850 (no. 444 in Herb. Gray). Mohr collected it in the 

 valley of the Comal River, New Braunfels, in 1850. I collected it at San 

 Antonio, Bexar County, in 1881, and Bush also collected it at San Antonio 

 October 1900 (no. 1246), September 1901 (no. 797), and March 1902 and 1903 

 (nos. 1 172, 3677). Palmer's collections of this tree are from Sutherland 

 Springs, Wilson County (no. 9302), Goliad, Goliad County (no. 9128), San 

 Marcos, Hays County (no. 13311), dry limestone banks. South Llano River, 

 Telegraph, Kimble County (no. 10931). 



C. Lindheimerii is most abundant in the neighborhood of streams and springs 

 and occurs less commonly on higher ground. I have no evidence that it grows 

 on the Edwards Plateau or westward.

 1884; Garden and Forest 3:40. ^g. 12. 1890. — C. mississippiensis 

 var. reticulata Sargent, Silva N. Am. 7:72 (in part). 1895; Man. 

 301. fig. 243. 1905. — C. reticulata, C. Lindheimerii, and C. Douglasii 

 are similar in their thick leaves, rough on the upper surface and 

 conspicuously reticulate venulose below, and in their pedicels longer 

 than the petioles. The entire leaves green on the lower surface and 

 the orange-red fruit on shorter pedicels of C. reticulata distinguish 

 it from C. Douglasii. The shape of the leaves of C. Lindheimerii, 

 pale and pubescent below over their whole surface, makes it easy 

 to distinguish that species from C. reticulata. 



I have not seen the flowers and spring leaves of C. reticidala, which, although 

 it was described 90 years ago, is still very imperfectly known. The young
