1919.] NATURAL SCIENCES OF PHILADELPHIA. 257 



Flowering in July and August, fruiting in August and September. 

 Corolla externally pale-greenish, on posterior side brownish, within 

 purple-brown on posterior side (on and below posterior lobes, and 

 posterior half of antero-lateral lobes), anteriorly (elsewhere) pale- 

 greenish. Sterile filament dark purple-brown. 



The northern Scrophularia leporella Bickn., easily distinguished 

 by its yellow sterile filament, its more cut leaves and its . earlier 

 flowering season (for fuller contrast see Torreya 19: 118), is to be 

 looked for in upland North Carolina* and Tennessee. 



The type of Scrophularia serrulata Small, Fl. S. E. Un. St. 1058, 

 1337. 1903, "Type Ga., Chapman, in Herb. C. U.," appears to be a 

 specimen of the Palsearctic Scrophularia nodosa L. The plant is 

 from the Chapman herbarium but without indication of collector; 

 certainly some confusing of data has occurred, or perhaps the speci- 

 men is from Georgia in the Caucasus.

CoUinsia verna Nutt., 1. c. 190. pi. 8. 1817. "On descending the Ohio 

 . . . nearly to Galiopolis, ... I recognized it on the more open 

 alluvions of the river, withered and nearly past aflfording seed. . . . 

 From these seeds ... I have been fortunate enough to obtain the 

 plant from which the accompanying drawing was taken by . . . 

 M. C. A. Le Sueur." Type seen in Herb. Academy of Natural Sciences
