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 smail 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 Linnzeus. 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, Keellia, 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 Fritéllaria coccinea & 
Fritillaria recurva coccinea, Callichroa nutans & Blepharipappus 
nutans, Plagiobothrys 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 Phenogamic Flora of Mexico. By B. lL. 
Roprnson and H. E. SEATOon, 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 Zorrey 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.
