furnished no means of determining to which of these classes any- 

 given name belongs. For instance, Miss Vail is credited with a 

 list of species of Meibomia, only one of which was described by 

 her, and none at the place cited; and McMillan is credited with 

 six species of Pleurolobus. Only the comparatively small num- 

 ber of botanists who concern themselves with changes in nomen- 

 clature are likely to remember that these are but familiar species 

 of Desmodium, many of them described by Linnaeus. Professor 

 Greene is credited with fifteen new species of Blepharipappus, 

 which are only renamed Layias, and twenty-four species of Lin- 

 anthus, all but one of them long-described and well-known 

 Gilias. In like case are all the new species of Platystemon, 

 Bicuculla, Caprifolium, Jacksonia, Lesquerella, Nasturtium, 

 Stellularia, Hesperalcea, Kuhnistera, Kunzia, Lutkea, Therofon, 

 Stellaria, Arracacia, Myrrhis, Symphoricarpus, Caprifolium, 

 Ereminula, Lappula, Koellia, Tullia, Salvia, Ramona, Mirabilis, 

 Neckeria, Razoumofskya, Manihot, Scoria, Ostrya, Leptorchis, 

 Corallorhiza, Gyrostachys, etc., etc. In a number of instances 

 the same species — even those considered the same by their 

 author — is listed twice, as in the case of Fritillaria coccinea & 

 Fritillaria reciirva coccinea, Callichroa nutans & Blephatipapptcs 

 nutans, Ptagiobothrys Californicus & P- campestris. These 

 serious errors are so easily remediable by the use of different 

 type or by double citation that we hope to see the next list 

 free from them. 



Additions to the Plicenoganiic Flora of Mexico. By B. ly. 

 Robinson and H. E. Seaton, being No. 3 of the New Series of 

 Contributions from the Gray Herbarium of Harvard University. 

 In it twenty-nine new species and several varieties are described. 



In the Torrey Club Bulletin for July, Dr. Britton has been 

 doing useful work in looking up the authenticity of some of 

 Rafinesque's genera recently attempted to be revived. Pseva, 

 which Dr. Kuntze has taken as the older name of Chimaphila, 

 in which action he was precipitately followed by Professor 

 Greene, is shown to have no foundation. It rests upon 

 Rafinesque's statement, published in the Journal de Physique, 

 1819, that ''Chimaphila Pursh is antedated by Pseva, Raf Med.
