Kulinia § Strigia, DC. — Critonia, Gartn., not of/?. Br. 



Heads 10-25-flowered. Scales of the involucre lanceolate, rather loosely 

 imbricated in two or three series; the exterior shorter, acute or acuminate. 

 Receptacle naked. Corolla tubular, somewhat dilated at the base, not ex- 

 panded above, 6-toothed ; the teeth short, obtuse, glandular externally. 

 Style with a villous bulb at the base ; the branches at length exserted, slight- 

 ly clavate and somewhat flattened at the summit, glabrous. (Anthers some- 

 times abortive or unconnected?) Achenia nearly cylindrical, many-striate, 

 sessile. Pappus a single series of strongly plumose bristles. — Perennial 

 herbs or suifrutescent plants, with alternate or somewhat ojiposite 1-nerved 

 or tripli-nerved lanceolate leaves, sprinkled with resinous dots beneath. 

 Heads paniculate-corymbose. Flowers white or purple. 



"We have drawn the above character from the North American species alone, to 

 which, with probably K. rosmarinifolia of Cuba (the section Strigia, DC.) the ge- 

 nus should doubtless be restricted: the species with pentagonal estriate achenia 

 seem to be closely allied to Eupatorium, while Kuhnia proper is more near to Cla- 

 vigera. — Kuhnia glutinosa of tUiott is placed by De CandoUe in his section Leio- 

 go°iia, and is referred by Hooker to Eupatorium altissimum, in both cases on the 

 authority of specimens communicated by the author himself who had inadvertendy 

 sent under that name the Eupatorium aUissimum, a very different plant frorn the K. 

 glutinosa of his herbarium (also long since sent to his correspondents in this coun- 

 try), and by no means agreeing with his published description, in which the pappus 

 is said to be "beautifully feathered."— Kuhnia Arabica, Hochst. tf- Steu/i.! pi. Arab, 

 un. itin.; DC! prodr. 7. p. 267, is a species of Pegolettia, as Dr. A molt first inti- 

 mated to us.— Nothites, Cass, (of which we know a single species) is nearer Kuhnia 

 than Mikania, but a distinct genus. 



1. K. eupatorioides (Linn.): stem herbaceous; leaves, as w^ell as the 

 scales of the involucre, thickly sprinkled beneath with shining resinous dots, 

 lanceolate; the cauline ones txiostly irregularly serrate; those of the branches 

 narrow and usuallv entire; heads in paniculate corymbs; flowers white or 

 yellowish-white.— L?>?». I. c. (excl. syn. Pluk.) ; Linn. f. decad. 2. p. 21,

p. corymbulosa: lower surface of the leaves, and the branches, cinereous- 

 pubescent; lower leaves ovate-lanceolate, irregularly serrate or sometimes 

 laciniate-toothed ; corymbs rather short and dense. — K. eupatorioides, Ell.

y. gracilis: leaves scarcely pubescent; the lower cauline ones lanceolate 

 and more or less serrate; the others linear and mostly entire; corymbs loose, 

 paniculate.— K. paniculata, Cass. diet. 2i. p. 516; DC! I. c. K. Critonia,

Dry soil, New Jersey ! and Pennsylvania! to Florida! Alabama! Lou-

 nia pubescent when young, nearly glabrous when mature. Pappus white 

 or tawny. — The K. eupatorioides of Linnaeus, and the Critonia Kuhnia of 

 Ga;rtner were clearly founded on the same plant, and that the more common 

 form in New Jersey and Pennsylvania, which is rather the K. Critonia of 

 authors than K. eupatorioides; so that some changes in nomenclature would
