no comment as to their relationship or identity. Bigelow in 

 his "Florula Bostoniensis, " second edition, 1824, p. 327, gives 

 only C. parviflorum Willd. and, as a synonym, G. calceolus Mx. 

 The description there given will apply as well to one form as 

 the other; that is, as well to G. hirsutum Mill, as to G. parvi- 

 florum Sails b. 



Dr. Torrey, in his "Flora of the State of New York,'' Vol. 

 2, page 287, says: "This G. parviflorum Salisb. and the preced- 

 ing species, G. ijubescens Swartz, are very nearly allied, and 

 many of our botanists do not consider them distinct. Since my 

 attention has been particularly directed to these plants, I have 

 had no opportunities of comparing them in the living state. 

 The diagnostic characters given above are those of Hooker, 

 who has no doubt (having examined cultivated specimens) that 

 they are perfectly distinct. " On comparing the characters of 

 the two forms the only diiference discernible is the size and 

 depression of the lip, the form of the sepals, and some imagi- 

 nary distinctions in the coloring of the sepals and petals. 



Amos Eaton, in his "Manual of Botany of North America, " 

 seventh edition, 1836, page 271, gives, after eliminating the 

 commoa phrases, the following for G. j^arviflorum, ' Lobes of 

 the style triangular, acute," and for G pubescens, "Lobes of the 

 style triangular, oblong, obtuse " The other apparent differ- 

 ences are merely a play on words. 



Professor Rafinesque, in his "Medical Flora," edition, 1828, 

 page 142, says, "Many botanists have made two species, G. 

 pubescens and G. parviflorum of this, to which the previous and 

 better name of G. lateum ought to be restored. I have ascer- 

 tained that they form only one species, affording many varie- 

 ties, some of which are: var. picbescens, entirely pubescent, even 

 the flowers; var. glabrum, nearly smooth; var. grandiflorum, 

 slightly pubescent, labellum very large; var. parviflorum^ 

 slightly pubescent, labellum very small; var. maculatum, label- 

 lum more or less spotted, with red dots, lobule often red; var. 

 biflorum, with two flowers and bracteoles; var. concolor, the 

 whole flower yellow or yellowish, unspotted; var. angustifolium, 

 leaves and bracteoles lanceolate. A multitude of intermediate 

 varieties or deviations may be seen, with undulate or spiral 

 sepals, obtuse or acute lobule, broader or narrower leaves, etc. " 



While all this may not be to the reader's taste yet the 

 description together with the figure given leaves no doubt in 

 our minds as to what Rafinesque referred and further it well
