Donia ciliata; foliis oblongis obtusis semiamplexicaulibus ciliato-serratis, 
laciniis calycinis ——— planis, seto acuminatis, caule herbaceo.— 
Nutt. 
Donia ciliata, Nurratt, in Journ. of the Voataiey of Nat. Sciences of Phila- 
delphia, vol. ii. (1821), p. 118. 
Root subfusiform, fibrous, biennial. Stem from 1 to 2 feet high (in its wise 
country 4 or 5 feet), erect, branched, furrowed, glabrous, the branches 
proceeding from the axils of the leaves. Leaves from 2 to 4 inches long, 
oblong, obtuse, slightly concave, rigid, waved, gradually smaller upwards, 
the margins strikingly ciliato-serrate, the midrib strong, keeled at the 
base, and forming a swelling where it is inserted upon the stem; with 
indistinct lateral nerves. The whole substance of the leaf is beautifully 
reticulated with pellucid veins, as may be seen by holding it up ol 
the light. 
i lowers solitary, terminal upon the stems and branches, yellow, showy. In- 
volucres hemispherical, formed of numerous linear imbricated scales, of 
which the outer ones are squarrose, the inner ones erect, all of them acu- 
minate, and almost aristate. Receptacle naked, pitted. Florets of the ray 
ligulate, patent, bidentate; Germen destitute of pappus; Florets of the 
disk tubular, 5-toothed ; Stamens yellow; Anther with an acute appen- 
dage at the top, none at the base ; Germen pappose ; Stigmas two, fili- 
form, pubescent ; Seed or Pericarp ere) ; Pappus sessile, of nu- 
merous scabrous bristles. 
Evidently allied to the Donia squarrosa of PursuH and of 
the Botanical Magazine, t. 1706, but differing from it, even 
at first sight, in its smaller flowers, and in the shorter scales of 
the involucre, and more especially in its far larger leaves, which
