94 Pennell : Plants of the southern United States 



About Wilmington, North Carolina, he was in yet another district 

 of unusual interest, in aspect recalling the open grassy pine-lands 

 further south. 



In 1913, from August 22 to October 20, the writer was again 

 in the field, traversing districts inland from, or west of, those 

 visited the year before. In the Mississippi Valley collections 

 were made in Indiana, Illinois, Missouri, especially in the eastern 

 (Cambrian) Ozark region, Arkansas and Oklahoma. Most of 

 September was spent in Texas, through the Black Belt, in the 

 Edwards Plateau northwest of New Braunfels and at Boerne, in 

 the coastal plain eastward from Cuero and Victoria to Rosenberg, 

 and in the pine-land of the southeast. Late September and early 

 October he was in the pine-land of western Louisiana, in Arkansas, 

 in the mountains of northeastern Alabama and eastern Tennessee, 

 and about Stone Mountain, Georgia. Detailed itineraries of the 

 routes of both seasons will be published in the writer's "Agalinis 

 and Allies in North America."* 



All specimens collected by the writer, unless otherwise specified, 

 are in the herbarium of the University of Pennsylvania. Some 

 of these are represented by duplicates in the herbarium of the 

 New York Botanical Garden, and in other herbaria. In the 

 following lists numbers cited in parentheses are those of the writer's 

 collecting. For groups critically studied specimens are cited from 

 various herbaria indicated by letters as follows: 



Academy of Natural Sciences, Philadelphia (A.) 



Biltmore Herbarium, Biltmore, North Carolina (B.) 



Missouri Botanical Garden, St. Louis (M.) 



University of Pennsyh-ania, Philadelphia (P-) 



United States National Museum, Washington (U.) 



New York Botanical Garden, New York City (Y.) 



To the custodians of all the above herbaria the writer is 

 indebted. In an especial degree he must acknowledge the kind- 

 ness of Dr. John M. Macfarlane, of the University of Pennsylvania, 

 whose interest made possible the collecting of the specimens 

 recorded as well as much of the opportunity for their study. This 

 study has been conducted at the University of Pennsylvania and 

 at the New York Botanical Garden.
