Plante Lindheimeriane. 157 
specimens of No. 85, Pl. Fendl., 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. & 
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 a. Planchon, l. c. As to his L. Boottii g. 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. Tf 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.
