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 (1819), but 
I cannot see that his position is tenable. Jacksonia is published 
at the place above cited as follows: __ 
_ Jacksonia (trifoliata)—Cleome dodecandra, L. Now Cleome 
dodecandra, L. Sp. Pl. 672° is a well-known Indian species. 
Rafinesque evidently followed Michaux in supposing that it was 
North American, and Cleome dodecandra, Michx. F|. Bor. Amer. 
li. 32 (1803) is indubitably the same as Polanisia graveolens, Raf. 
Amer. Journ. Sci. i. 379 (1819), and not at all the plant of Lin- 
neus. In matters of nomenclature we must be exact, and so it 
Seems to me that /acksonia, Raf., can only apply to the Asiatic, 
Linnean, Cleome dodecandya. 1 do not find any allusion to Jack- 
Sonia in subsequent writings of Rafinesque, and presume that he 
_ discovered his error. 
Alsine, L. Sp. Pl. 272 (1753). I note that this generic name 
must, on the recognition of priority of place, and the beginning of 
nomenclature in 1753, cieany displace Stellaria, L. Sp. Pl. 421 
(1753). 
As given in the Species Plantarum, the Linnean Alsine is 
composed of A. media (Stellaria media, = and A. por’ |
