Plant ce Lindheimeriana. 157 



specimens of No. 85, PL Fend I., which I should now refer to 

 L. rigidum, Pursh. I believe that I have also noticed them 

 in L. Virginianum ; but they do not appear in any of the 

 specimens preserved in my herbarium. The localities from 

 the eastern parts of the United States, cited from Torr. &f 

 Gr. Fl. N. Amer. by Planchon under L. Berlandieri, belong 

 to his L. Boottii, as I suppose does also the whole of what 

 is called L. rigidum in New England, &c. At least this is 

 the case with the plant gathered at New Haven by Oakes, 

 and at Providence by Mr. Olney. The latter is exactly L. 

 Boottii o. Planchon, I. c. As to his L. Bootlii B. from Texas, 

 by Lindheimer, I fortunately possess a corresponding speci- 

 men, supplied by Engelmann subsequently to the distribution 

 of Lindheimer's former collections, and named "L. rigidum" 

 on a ticket bearing the printed number 118, which number 

 has been erased with the pen. This explains its occurrence 

 in the same way in herb. Hooker. The root is annual. If it 

 be a distinct species, as is most likely, still it appears, from 

 what has already been stated, the stipular glands cannot be 

 entirely relied upon for a character. Planchon has omitted 

 to notice the more or less glanduliferous-ciliate margins of the 

 sepals, which are conspicuous in most cases, and caused the 

 plant to be referred in the Flora of North America, &c. to 

 L. rigidum, to which it is very nearly related.
