counties have been referred to this species. It is also reported 

 from Scott county by Nagel and Haupt in Proceedings of 

 Davenport Academy of Sciences. 



We have long doubted that this is a valid species. At best 

 it very closely simulates the preceding. It is usually distin- 

 guished by its smaller size, brighter color and smaller size of 

 the lip, and the presence of a sweet odor. Our material affords 

 specimens varying in height from seven to twenty inches. 

 The color of the flowers of the specimens determined by Pro- 

 fessor Norton of the Missouri Botanical gardens, and of speci- 

 mens collected in Muscatine county by Mr. Reppert, agree with 

 the small stature and small flowered forms which may with 

 safety be referred to this species if such is possible. As to the 

 character of possessing an odor we have no faith in it what- 

 ever as a distinguishing factor. The length of the lip varies 

 in our material from one to one and a half inches, while the lip 

 of the preceding species varies in length from one to two 

 inches. Professors Beal and Wheeler in their "Flora of Michi- 

 gan," page 138, say that the preceding species is, "Much 

 coarser in every way, with strongly plaited hairy leaves, and 

 large light yellow flowers, more or less brown spotted. Small 

 forms of this are often mistaken for G. parviflorum, but the two 

 species are apparently distinct in Michigan. " Prom this plain 

 statement it will be readily perceived that the two forms at 

 best are not readily distinguished and further that the size of 

 the lip is no constant character. Britton and Brown in their 

 "Illustrated Flora," Vol. 1, page 459, admit that this form 

 appears to intergrade with the preceding, or of which it may 

 be but a form. Professor Gray in his Manual, sixth edition, 

 says it seems to pass into the preceding. Professor Wood, in 

 his Botanist and Florist, says that G. pubescens Sw., a synonym 

 for the preceding, has the "Stems usually clustered, " which is 

 contrary to our experience, though in more favored localities 

 this could readily be the case, and further, "Lip compressed 

 laterally, moccasin-shaped, leaves broadly lanceolate, " whereas 

 for G. parviflorum Salisb. he gives, "Leaves lanceolate, lip 

 depressed." The depression of the lip seems not to be con- 

 sidered of any importance by botanists generally, while any 

 distinction founded upon difference in the form of the leaves 

 will so far as these two forms are concerned end in disappoint- 

 ment. Professor MacMillan in his "Metaspermae of the 

 Minnesota Valley, " page 163, gives the two species but makes
