Rep. 1809." Dr. Britton says: " I wish to record here that I 

 have recently gone over these papers line by line, and can find 

 no allusion to Pseva in any of them, nor have I met with the 

 name in any of Rafinesque's writings except at the place where 

 he claims it as noted above." The attempt to resurrect an 

 earlier name for Polajiisia is disposed of as follows: "Jacksonia, 

 Raf. Med. Rep. (II) v, 352 (1808). Professor Greene has argued 

 in Pittonia ii, 174 and 274 that this name should replace Polanisia 

 Raf. Journ. Phys. Ixxxix, 98 (18 19) but I cannot see that his 

 position is tenable. Jackso7iia is published at the place above 

 cited as follows: 



Jacksonia {ixiioXioXa)^ Cleome dodeca7idra 'L,. Now Cleome 

 dadecandra, ly. Sp. Rl. 672 is a well-known Indian species. 

 Rafinesque evidentlj^ followed Michaux in supposing that it was 

 North American, and Cleome dodecandra Mich. Fl. Bor. Amer. ii, 

 32, 1803, is indubitably the same as Polanisia graveolens Raf. Amer. 

 Journ. Sci. i, 379 (18 19) and not at all the plant of lyinnaeus. In 

 matters of nomenclature we must be exact and so it seems to me 

 that Jacksonia Raf. can only apply to the Asiatic, lyinnaean, 

 Cleome dodecandra. I do not find any allusion to Jacksonia in 

 subsequent writings of Rafinesque, and presume that he dis- 

 covered his error." In the meantime, however. Professor Greene 

 has made haste to transfer* the species of Polanisia to Jacksonia 

 and under the head of " Corrections in Nomenclature " fto trans- 

 fer the three dozen species of the Australian, IvCguminous 

 g^nus Jackso7iia to another name. 



The Range of Amorpha fndicosa. By John M. HolzingeR 

 of the U. S. National Herbarium. Under this heading Mr. 

 Holzinger prints in Erythea for June some notes on specimens 

 belonging to the U. S. National Herbarium which show that the 

 range of the species is considerabl}^ farther extended than had 

 been supposed. In the course of his examinations he found that 

 the three sheets of this group belonging to Professor Greene's 

 herbarium, two of them labeled A. Californica Nutt. and one A. 

 hispidnla Greene, were in his opinion incorrectly named. Con- 

 cerning them he wrote: " There seems to have existed a long
