tomous ; leaves petiolate, elliptical lanceolate, acuminate, smooth, yellowish glau- 

 cous beneath ; cyme erect, pedunculate, axillary to the last dichotomies and much 

 shorter, naked and trichotomous. — A shrub four to five feet high, growing on 

 the banks of the Kentucky river. I described it in the Western Review, vol. 1. 

 p. 229. The C. albida of Erhart which is a distinct species, differs from it by 

 lanceolate leaves, not obliqual, dimidiate petiols, cyms terminal, &c. and the C. 

 polygama of Fl' Ludoviciana by sessile leaves, fruit black. &c. 



102. Houstonia ropestr,is. Smooth; stems fruticulose, assurgent and 'genicu- 

 late; leaves long-linear, attenuate and acute at both ends; flowers corymbose 

 paniculate ; pedoncles short, unequal ; divisions of the corolla lanceolate acute, 

 style exert, capsule elongate, — A small shrub, a foot high, growing on the cliffs 

 of the Kentucky river, and blossoming in August. It is very different from H. 

 tenuifolia of Nuttall which is not frutescent. 



103. Aparine (Galium L.J viscidifiora. Stem erect ; leaves quaternate, semi- 

 petiolate, ovate-lanceolate, nearly obtuse, trinerve, margin and nerves ciliate ; 

 flowers in divaricate, lateral, loose and trichotomous panicles; bracteas opposite 

 lanceolate ; peduncles long and slender ; corolla viscid, divisions ovate mucro- 

 nate, fruit smooth. — A pretty species with dark purple flowers ; it grows in the 

 Alleghany mountains of Maryland, &c. blossoming in June. Stem a foot high; 

 Perennial. The linnean name of Galium being nearly the same as Allium, the 

 former and better name of Toumefort ought to be employed instead. 



104. Cacalia paniculata Stem grooved ; leaves petiolate, rhomboidal, acute 

 at both ends: base entire, remainder unequally sinuate ; teeth large, acute: flow- 

 ers paniculate ; peduncles divaricate, with some small scaly bracteoles ; perian- 

 the five leaved, five flowered; phylles lanceolate, carinate. — It grows in the knob 

 hills of Kentucky, blossoming in August ; flowers white. 



105 Cacalia pteranthes. Stem grooved and crooked ; leaves petiolate, ovate 

 or lanceolate, acute thick laciniate ; flowers corymbose, paniculate ; peduncles 

 elongate : perianthe five leaved, five flowered; phylles oblong, with an undula- 

 ted wing on the back — It grows in the barrens of Indiana and Illinois. Flowers 

 white ■ it has much affinity with the foregoing. 



106. Solidago sphacelata. Stem striated, pubescent above; leaves petiolate, 

 ovate, acute, mucronate, serrated in the middle, rough on the edges and beneath, 

 inferior ones subcordate ; flowers sessile, lateral spikes loose, dense flowered and 

 short, the lower ones recurved, reflexed, the terminal one erect ; folioles of the 

 perianthe oblong, obtuse, brown or sphacelate at the end, adpressed, Hgules ob- 

 tuse, hardly longer. — It grows on the hills of Kentucky and Virginia, rising less 

 than two feet; leaves small, about an inch long; ; flowers of a dirty brownish 

 yellow, blossoming in August. Perennial. 



107. Solidago rupestris. Stem straight, slender, striated, pubescent above ; 

 leaves crowded, broad, linear, sessile, very acute, with faint remote serratures, 

 except at the end, smooth and trinervate ; flowers lateral, ascending, peduncula- 

 ted; racemes crowded, paniculated, elongate, flexuose, bracteate, divaricate, the 

 terminal one reflexed ; bracteoles subulate; folioles of the perianthe loose, subu- 

 late, acute ; ligules elongate, narrow, linear. — A fine species, growing on the 

 cliffs of the Kentucky river and blossoming in August ; flowers bright yellow ; 

 leaves slender, breadth only one-tenth of the length. Stem two feet high. It 

 has some affinity with S. odora but is not frEgrant. I had wrongly called it S par- 



' viflora in some specimens sent to several botanists. Perennial. 



108. Helianthus hirsutus. Hirsute ; leaves shortly petiolate ; lanceolate very 

 acute, remote, serrate, pale beneath, somewhat trinervate ; flowers terminal, soli- 

 tary, nearly sessile ; folioles of the perianthe adpressed, ovate, acute, ciliate, stria- 

 ted, brownish. — I found it on the knob hills of Kentucky, blossoming in August; 

 Stem two or three feet high, simple, covered with stiff grey hrirs very much 

 crowded, those of the leaves are more remote. Perennial. 



XXII N. G. Peramibus. Perianthe 12-16 partite on a single row, folioles al- 

 ternately longer and shorter ; eight sterile rays without ovary. Phoranthe con- 

 vex, paleaceous. Florets with a triangular ovary without teeth, tubulose cam- 

 panutate. Seeds triangular, naked, smooth. — This is another of the numerous 

 genera having affinities with Rudbeckia, Ratibida, Lepachys and Coreopsis, from 

 which it differs by the naked seed, &c. and from Obelisteca by the simple perian- 

 the, convex phoranthe and triangular seeds. The Coreopsis acuta, P. Cor. scabra 

 Fl. Ludov. and C. palmaia, rosea a.nd JMtdaio Nuttall, will belong either to this ge- 

 nus or to Obelisteca. The name means alternating around.
