154 SINGENESIA. JEa^ALIS. 



pappus through a lens scabious, often colouredj in the 

 following species purple.) 



Species. 1. V. noveboracensis. Common from Canada 

 to Virginia. 2. prcealta. 



3. * uUisshna. Leaves lanceolate, serrate, scabrous; slem 

 smooth; calix small and hemispherical, scales appressed, 

 ovate, acute, ciliate, awnless. Hae. Near Savannah in 

 Georgia, and throughout the states of Ohio and Kentucky, 

 on the margins of streams and swamps, very common, 

 and constant to the above character, which may perliaps, 

 at the same time, designate nothing more than the true 

 V. praaHa, but certainly not the plant so described by 

 WUldenow, Michaux, Pursh, and T'ersoon. — Stem 6 to 12 

 feet high, leaves very long, nearly smooth on both sides, 

 though scabrous; stem smooth and brown. Flowers very 

 numerous and small; inner scales of the calix obtuse, 

 without points, external merely acute, and with the points 

 appresscd. r. s. Anonymous, in Herb. Muhl. Obs. In all 

 the above species the seeds are almost perfectly smooth. 



A. J'nscindaia. 5. angustifolia. From Carolina to Florida. 



6. * scaherrima. 1 eaves linear-lanceolate, acute, closely 

 sessile and very scabrous, nearly entire; corymb subum- 

 bellate, few-flowered; scales of the calix lanceolate and 

 naked, filifornily acuminated. Uab. From South Caro- 

 Jinia to Florida. Obs. Stem about 2 feet high, simple, 

 slender, hirsute below, smooth above. Leaves about 2 

 inches long, varying in breadth, mucronately acute, now 

 and then remotely serrulate, sessile, sometimes subam- 

 plexicaule, approximating but not crowded. Corymb 

 small, from 5 to 10 or more flowered. Calix scales fili- 

 formly terminated as in V- noveboracensis. 



7. oligophylla. Obs. Stem nearly naked, about 18 inches 

 high; corymb irregularly branched or paniculate; scales 

 of the calix lanceolate, acuminate. Kab. In North and 

 South Carohna; to me a very rare plant. Growing in low 

 and swampy Pine forests. Note. In species 5, 6, and 

 7, the sirjatures of the seed are strigosely pubescent, 

 .seen through a lens, and the pappus more distinctly sca- 

 brous; these consequently approach to the genus Liatris, 

 but possess the double pappus. 



An American genus, with the exception of V. anthel- 

 mintica of India, the 10 other species comprisin.^the ge- 

 nus are indigenous to the tropical regions of America. 



541. KUHNIA. WUldenow. 



Calix imbricate, cylindric. Receptacle naked.
