150 SYNGENESIA. SVPERFLUA. 



*Chrysopsis. t Calix imbricated. Rays of 

 rtie corolla mostly yellow. Anthers naked at the 

 base. Receptacle naked. Pappus double, exterior 

 paleaceous, minute, interior scabrous, many-rayed. 

 Seeds obovate, villous. 



Herbaceous; flowers fastigiate, subcorymbose, stem 

 simple or paniculalely branched; radial florets rarely ever 

 more numerous than in Aster, to which this subgenus is 

 very closely related. — Scales of the calix unequal, rigid, 

 subcarinate, and pointed; anthers naked, or not bisetose 

 at the base. Minute exterior, paleaceous pappus, white, 

 the interior conspicuously scabrous, (through a common 

 lens) often fuscous or rufescent, consisting of more than 

 40 rigid rays. \ 



Species. 2. gomipina. From Virginia to Florida. 

 Abundant throughout the Pine-barrens of North Carolina, 

 particularly near Wilmington. — PerenniaU leaves all en- 

 tire, radical ones spathulate-lanceolate, cauline cuneate- 

 oblong, obtuse, with a point, lanuginous, in common with 

 the whole plant, except the corolla; peduncles fastigiate, 

 corymbose, l-fiowered; flower bright r^olden-yellow, larg- 

 er than tiiat of C maviuna; radial florets about 25. Pap- 

 pus rufescent, rigid and conspicuously scabrous; external 

 minute, paleaceous, simple and white; seed obovate, vil- 

 lous. The aspect of this species is more like tiiat of the 

 European Inula than any other in this Catalogue, but the 

 anthers are not bisetose at the base. 



3. • trichophylla. Corymb simple; leaves entire, oblong, 

 obtuse, subaraplexicaule, lanuginously pilose, and sca- 

 brous on the margin, diminishing upwards; fastigiate pe- 

 duncles and hemispherical calix smooth. Hab. In North 

 and South Carolina and Georgia. It appears to be an in- 

 termediate species betwixt the preceding and C. mariana. 

 Obs. Perennial; upper leaves oblong-lanceolate, green, 

 and sparingly lanuginous; stem 12 to 18 inches high, 

 simple, nearly smooth, attenuated upwards, 3 to 6, or 9- 



f In allusion to the prevailing yellow colour of the flowers. 



\ Note. Imda dysenterica and I. Pulicaria also possess a dou- 

 ble pappus, but in these the anthers are bisetose at the base, 

 and the rays of the pilose pappus in the first about 24, and in 

 PnUcaria only 8 or 10; the radial florets are also very numerous 

 and linear. In the following species, I have observed the parl- 

 ous to be simple; viz. Imda Belejiium, I. briiamiica^ I germmii' 

 iia, I. ociihis Christiy I. odoruy I. Vaillantiiy I. crithniifoliat I. sua- 

 veolens, I.japonicuy I. sijiiavrosa, and/- hirta; in most of these 

 the vinthers are also bisetose.
