284 ' DESCRIPTIONS OF NEW SPECIES 
Tribe II. EUPATORIACE. (Lessing, Decand.) 
LIATRIS. 
Liatris brachystachya. (Nutr.) Arkansa; also in the prairies of Missouri, 
common. Liatris pychnostachya? Muicu. Vol. IL, p. 91. 
Liatris oppositifolia (NuTT.) is a species of Hupatorium. 
Liatris virgata, (Nurv.) nearly smooth; root tuberous; stem often paniculately 
and virgately branched; the flowers sometimes upon short, but usually on long 
pedicels; involucrum subhemispherical; fifteen to twenty flowered ; scales oval, 
nearly all equal and imbricate, somewhat acute or obtuse; pappus rather short, 
slightly plumose; receptacle naked, or bracteolate—Has. In the pine forests of 
Georgia, and near Newbern, N. Carolina. Very peculiar in its great tendency 
to branching; the branches slender. Leaves linear, sublanceolate, not remark- 
ably unequal; erect, or reflected; smooth, or somewhat ciliated. One speci- 
men, which I cultivated at Cambridge, Mass., had a bracteolate receptacle, with 
a foliaceous scale to each floret; in this individual the leaves were reflected, 
I give the following apparently new genus of VeRNontacE®, allied to Vernonia, collected by 
the late Doctor Baldwin on some part of the Pacific coast of South Ameriea, and from its curious 
honey-combed receptacle, I have called it 
* SYMBLOMERIA. 
_ Capitulum many-flowered, homogamous; the florets tubular and deeply five-cleft, with linear 
segments, the exterior series subpalmate. Receptaculum pitted with angular cavities like 
a honey-comb, in which the turbinate villous achenium is almost wholly immersed, (as in Bald- 
winia.) Involucrum hemi herical, imbricate, and somewhat squarrose, in several unequal series, 
the scales adnate at their base. as with the branches filiform and pubescent, acuminate. 
Pappus double, and, in several is ME and much shorter, all paleaceously bristly.— 
A shrub eight or ten feet high, with alternate, lanceolate, ‘acuminate, entire, smooth leaves; capi- 
tuli rather large, axillary and terminal, pedicellate and corymbose (florets apparently white, judg- 
ing by the dried specimen.) 
Symblomeria Baldwiniana. 
A branching shrub with terete somewhat cinereous puberulous branches and young shoots. 
Leaves about three inches long, an inch to an inch and a half wide, acuminate at each end. Ca- 
pituli a little larger than those of Vernonia noveboracensis,
