2. Notes on some American Species of Utricularia, 



9 



These notes were suggested by an inspection of the colored draw- 

 ings which were prepared by Major John Le Conte to illustrate his 

 *' Observations on the North American Species of the Genus Utricu- 

 laria," whicb was published in the year 1824 in the first volume of the 

 Aiinals of the Lyceum of Natural History, New York, pp. 72-79. 

 Only rude outlines of the flowers, copied from these colored drawings, 

 were published in this paper. After the death of Major Le Conte, 

 the original drawings for this paper, along with those of his corre- 

 sponding papers upon Viola and Gratiola, came into the possession of 

 Mr. I. C. Martindale, in whose careful hands these interestinof data 

 are likely to be preserved, as they ought to be. Mr. Martindale 

 obligingly lent them to me at a time when I was led to believe that 

 Le Conte's Utricularia personata had been wrongly combined with the 

 U. cornuta of Micliaux. 



Major Le Conte, in his memoir upon the genus, insisted that he had 

 never seen Utricularia cornuta of Michaux ; but his U. pe)-sonata is 

 said to inhabit bogs from New England to Florida, a district over 

 which U. cornuta abounds, extending quite to the northern parts of 

 Canada. It seemed certain, therefore, that he had unwittingly included 

 U. cornuta in his U. persojiata^ although the charactei'S of flowers 

 racemed, and lower lip of corolla small, showed that he had in view a 

 Southern form to which these particulars apply. So we had admitted 

 only one species of this peculiar group, allowing it to be quite vari- 

 able ; and Benjamin (in Linnoea, xx. 305, and in Mart, ¥\, Bras. x. 

 240) did the same, referring to U. cornuta not only U personata, but 

 U. jimcea of Vahl, a native of Guiana. But there is a small flowered 

 racemose form in the Southern Atlantic States which one cannot with- 

 out much forcin" combme with the larije- and few-flowered U. cornuta. 

 And now Le Conte's original drawings for U. personata are found 

 to represent the small-flowered form in question. His drawing is of 

 a plant bearing seven racemosely scattered flowers, with corolla not 

 over four lines long, and the spur filiform. Although we have no 

 specimens from Brazil or Guiana, I jndge that this form does extend 

 to these countries, and that it is the U. juncea of Vahl, a name to be 

 retained. From C. Wright's Cuban collection it appears that both 

 this and the true U. cornuta are in Cuba. One can hardly draw up a 

 clear diagnosis ; but the following may serve, 



U. CORNUTA, Michx. Stem 1-5-flowered, the flowers approximate 

 at summit : lips of the corolla half-inch long; lower with the two sides
