yellow cylinder of antherae surrounds the pistillum, which 

 here, as in the ray-florets, is divided. The receptacle is fur- 

 nished with short cilia. The fruit is an angular paryopsis, 

 of which the inferior umbilicus is furnished with a persistent 

 funiculus umbilicalis. The caryopses are provided with sharp 

 cilia, and have a sharp-haired pappus. 



Diagnosis aud Affinity. 



There is a distinct variety of this plant, with small 

 lanceolate leaves, which is figured in the Fl. Dan. 1524. 

 as the Arnica angustifolia Vahl. of Greenland. Linnaeus 

 (Fl. Lappon. n. 305.) mentions the same plant under Doro- 

 nicum foliis lanccolatis, and maintains that it is a peculiar spe- 

 cie?. But he cites, at the ^ame. i\me, Doronicum IV. Chis. 

 Fannon. 522. and Alisma Matthioli J. Bauh. Hist. 3. 20, 

 both of which figures perfectly correspond with our A. mon- 

 tana. Chrysanthemum latifolium mifius Ger. Emac. 742. 

 might also be mentioned on the same occasion. In the later 

 editions of the Species Planiarum this plant is mentioned in 

 the Flora of Lapland, as a variety of A, montana. Nut- 

 tall (Amer. Plants, 2. 164.) also recogi[iises A. fulgens 2iX)A 

 j)Iantaginea Pursh, as varieties which grow ip J^abrador, 

 and on the Missouri. The former small-leaved specie^ is 

 mentioned by Linnaeys in a letter to J, G. Gmelin (Fl. Sib. 

 2. 153.) as a variety, produced by its situation pn high moun- 

 tains. That which bears the greatest resemblance to our 

 plant is A. doronicunri-) which is distinguished, however, by the 

 alternate position and dentated margin of its upper leaves. 

 The genus Arnica is in other respects difficult to be distinguish- 

 ed from Doi'onicum, for both have a double row of leaflets in 

 the calyx, both have a hairy receptacle, abortive filaments ii; 

 the ligulate flprets,and a pappus with sharp-pointed hairs. The. 

 only diflerence is, that in Doronicum the marginal seeds have 

 no pappus. Doronicum plaiitagineum, which is very like oui: 

 plant, is distinguished from it, partly by the geneiic charac- 

 ter, partly by the alternate, imperfectly dentated teeth, an^ 

 ]by the pale yellow, almost inodorous flowers.
