12. S. Harbisonii Schneider. — See Schneider in this Jour. i. 29. — It 



should be mentioned that there has been described a S. caroliniana by 

 Michaux, Fl. Bor. Am. n. 226 (1803), from "Carolina et Georgia/' He 

 cites S. pentandra Walter as a synonym, and that species is the same as 

 S. nigra Marshall. From the description it remains uncertain what 

 form Michaux had in mind, and most of the authors have regarded his 

 caroliniana as nothing but nigra. Nevertheless it might be identical with 

 S. Harbisonii but unfortunately no type specimen seems to exist in Mi- 

 chaux's herbarium at Paris.

1 With regard to the footnote given (1. c.) on p. 322 I received the following statement 

 from Mr. Johnston in a letter dated Oct. 28, 1919: "1 sec in your recent synopsis of 

 the willows of the section Longifoliae (p. 322) that I apparently gave some confusing 

 information. As, no doubt, you suspected the data given in the footnote should refer 

 to my collection No. 1241 from Cucamonga Canyon rather than to my No. 1243 from 

 Red Hill as it is given. Concerning the Red Hill collection (No. 1243 



43) the following 



data may be given:
