Sclimidel and Reiclienbach. If that be taken for a variety of TJ. vul- 

 garis., all the more should the U. macrorhiza of Le Conte, an extreme 

 form of the common N. American species. I have never seen a spur 

 of the latter so long in proportion and so abruptly contracted as in 

 Le Coute's figure. 



" U. STRIATA." The drawing bears the name of " U. hijiora, Vahl," 

 which in the monograph this is thought probably to be. A diagnosis 

 written in pencil under the figure seems to identify it with U. striata, 

 and begins with " caule bi-trifloro." The published character in the 

 monograph says " 5-6-flowered," which is certainly wrong. The figure 

 has only two flowers, on a stem barely a span high, which is smaller 

 than usual. It represents the species which has been always taken for 

 U. striata, and which is referred in the Synoptical Flora to U. fibrosa, 

 Walt. But the outline of tlie flower in the monograph (fig. 4) is not 

 taken from the drawing, nor from any figure in the collection, and the 

 spur in the two does not quite correspond. So that the identification 

 is rather doubtful. 



" U. GiBBA." From the drawing (6-flowered) and the description 

 (4:-7-flowered), this should be U. minor, L., except that the proportion 

 of the parts of the corolla is that of U. gibha. 



" U. FORNICATA." The drawing which I suppose to represent this 

 species bears no name. It is obviously U. gibba, L. 



'' U. LONGiROSTRis " obviously represents the species which I take 

 for U. bifiora, Lam. This name should therefore in the Flora be made 

 a synonym of that species, and be excluded from U. fibrosa. 



" U. INTEGRA," from the drawing (if rightly identified, for it is with- 

 out name), as well as from the description, I judge to be specifically 

 the same as the last preceding, the spur rather stouter. Only the tip 

 of it is represented in fig. 8 of the monograph. 



" U. PURPUREA." It is the large-flowered form that is represented, 

 probably fiom New Jersey. 



" U. PERSON ATA." Vide supra. 



" U. SETACEA." The U. subulata, L., of which it is said that " nothing 

 worthy the name of a description exists." This is true as to Gronovius 

 and Linnanis. Both were evidently puzzled by Clayton's '• Pyrola 

 floribus albis si)icatis," etc., which somehow or other got affixed to this 

 Utricular ia in the manuscript. 



U. CORXUTA, Michx., is barely enumerated in the monograph, but 

 not figured, having been confounded with U. personata. Vide sxpra. 



Two other tropical species claim a place in our flora, having been 

 detected in Florida.
