tinction between G. inuloides, glutinosa, and ciliata. The 
present may, I believe, be safely referred to the former of 
these species. It is a much taller and ranker growing 
plant than G. squamosa, and has less rigid and less spinous 
teeth, and is a much shyer flowering plant : but the flowers 
are considerably larger and handsomer. In regard to the 
Genus, Mr. Brown has expressed his opinion that GrinpELIA 
and Donia ought to be united. Lessine has kept them sepa- 
rate, and even placed them in a distinct subsection of his As- 
TEREE ; the one chiefly distinguished by the caudate anthers, 
including Donia glutinosa, (to which he adds as a conge- 
ner D. Canariensis,—Burutuatmum, Brouss.,) while Grin- 
DELIA is referred to a division whose anthers are destitute of 
awns. But as this proves to be the case also, according to 
Mr. Arnorr, with D. glutinosa,so the D. Canariensis ought 
alone to remain in Donia. 
This plant was detected in Texas by Mr. Drummonp, and 
from seeds sent by him our specimens were raised, which 
flowered in the open border of the Glasgow Botanic Garden 
in September, 1835. 
Descr. Stems two feet and more high, much branched 
and slightly downy, especially above. Leaves alternate, 
the lower ones somewhat spathulate, the rest oblong, semi- 
amplexicaul, the uppermost ones broader at the base and 
linear, inclining to ovate, all of them of a somewhat mem- 
branaceous texture, glabrous, sharply toothed at the mar- 
gin. Flowers large, terminal, solitary, yellow. Involucre 
hemispherical, viscid, of numerous, subulate, squarrose 
scales. Receptacle convex, naked. Ligulate florets entire 
at the apex ; those of the disk, with included anthers: ger- 
mens of both obovate, compresso-triquetrous, with one or 
two long, flexible, very caducous bristles.
