164 ICOSAND. POLYGYN. 



brous above hairy beneath, petals ovate longer than the cal., 

 stem ascending. - E. B. t. 2389. 



HAB. Werron hill and the East rocks of Clova, G. Don. Fl. May, 

 June. U . 



This is the second a instance I have to record of a plant which' had 

 heretofore been considered a native of N. America only, having 

 been found upon the eastern side of Scotland by the late Mr. G. 

 Don. It is totally unlike any other British species j does not ex- 

 ceed 4 5 inches in height, and is terminated by 3 or 4 rather 

 large white flowers. 



8. P. Fragaria (barren Strawberry), leaves ternate, leaflets obo- 

 vate deeply serrated silky on both sides (especially beneath), 

 petals obcordote as long as the cal., stems procumbent. Poi- 

 ret, Encycl. Lightf.p. 268, and . B. t. 1785 (Fragaria 

 ster ills'). 



HAB. Woods, banks, and dry pastures. Fl. March, April. I/ . 



Peduncles terminal, single or two together. Flowers white. This 

 wants the essential character of Fragaria, and is rightly placed by 

 the continental authors in the present genus. Seeds, or rather 

 seed-vessels, rugose, not smooth as in Fragaria, according to 

 Smith's definition of that genus. 



9. TORMENTILLA. 



1. T. officinalis (common Tormentil), leaves ternate all sessile, 

 leaflets lanceolate inciso-serrate, stem nearly erect dichoto- 

 mous. Light/, p. 272 (T. erecta). E. B. t. 863. 



HAB. Barren and hea*thy places, common. Fl. June, July. I/. 

 Root large and woody, used medicinally, and by the Laplanders for 



staining leather of a red colour. Stem weak, 6 8 inches long. 



Peduncles axillary and terminal. Flowers rather small, yellow, 



drooping before expansion. 



2. T. reptans (trailing Tormentil), leaves ternate on footstalks, 

 leaflets obovato-cuneiform inciso-dentate, stem prostrate. 

 Lightf.p.273. ..*. 864. 



HAB. Borders of fields and waste places, but not common, Sibbald. 

 N. side of the canal, Fossil marsh, below the bridge, Hopk. Road- 

 side between Hamilton and Cambuslang, Mr. Murray. Near Kirk- 

 caldy, Mr. Stewart. Near Ardvorlich, Mr. Arnott. Road- side be- 

 tween Glasgow and the village of Bowling ; and near Moulinarn, 

 Perthshire, Maugh. Fl. June, July. U. . 



Stems prostrate, but not rooting, varying much in length. Flowers 

 twice the size of the last. This, as well as the lastspecies, has some- 

 times 5 petals and 10 calycine segments j and then the plant be- 

 comes a perfect Potentilla, with which it accords entirely in habit. 

 Many of the continental botanists, on these accounts, abolish the 

 genus Tormentilla : and Scopoli has done so with the remark ' ' Mo- 

 noculum hominem ab humano genere quis separabit?" 



a The first was Juncus tenuis.
