ably laid away and forgotten. Consequently it is quite annoying 

 to discover that from both regions a considerable number of 

 names have been omitted. It seems necessary- to make a brief 

 historical supplement to be added jointly to my two papers. 

 The cause of the omission of these well-described species, 

 all of Rafinesque, is that they were described in works so rare, 

 at least in Europe, that they were not seen by the compilers 

 of the Index Kewensis, that mar\-ellous summary of plant-names. 

 Of course, many other species and genera of Rafinesque have 

 been overlooked beside these few Scrophulariaceae. The only 

 large work of his not catalogued is the Autikon, and of the genera 

 in it I am publishing a list in the Bulletin of the Torrey Club. 

 The following Scrophulariaceae, excepting the last, are all 

 from that work, and were published in 1840 under the serial 

 numbers given, and on the pages whose numbers follow in 

 parentheses. I quote Rafinesque 's notes of occurrence, and add 

 explanations and comments.

With his own Gratiola rigida (Atl. Jour. 176. 1833) from Ar- 

 kansas or Texas, Rafinesque quite correctly identified the older 

 G. acuminata Walt., 1788, and, because both possessing all 

 four stamens fertile, he transferred them to the Oriental genus 

 Ambulia Lam. The plant is Mecardonia acuminata (Walt.) 

 Small. He now describes four varieties:
