Very similar to Tr. glomeratum, which, like this, is a small, procum- 

 bent, spreading plant, of 3 — 8 inches in length, and has also the 

 cal. segments recurved. Here, however, the plant is hairy, the 

 heads are ovate, the flowers are white, the leaves are faintly tooth- 

 ed, and the cal. segments are narrow : in Tr. glomeratum the plant 

 is glabrous, the heads are round, the /towers reddish, the leaves 

 strongly toothed, the cal. .segmentshroacl. Tiie flowers in both are 

 very small : and they both, in England, grow in the same situation. 



8. Tr. striatum (soft knotted Trefoil), heads terminal and ax- 

 illary ovate subsolitary subsessile, cal. striated hairy with un- 

 equal straight teetli, leaflets obcordate nearly entire pubescent.

HAB.^Dry pastures, as in Edinb. Park, abmidantly. Light/. Fl. June. 



From 4 — S or 10 inches long, more or less procumbent or rechned, 

 pubescent. Flowers small, purplish red. Cal. deeply furrowed, 

 swelling with 5 almost setaceous, straight, not recurved teeth. 



4-+- Cal. remarkably biflated after flowering. Standard of the Cor. 



deciduous. 



9. Twfragifenmi {Sir awlerry -headed Trefoil), heads upon long 

 stalks roundish, cal. after flowering inflated mcu)branaceous 

 pubescent two of the teeth setaceous refle.xed, stems creeping, 

 leaflets obcordate serrated. E. B i 1050. 



Hab. Moist pastures. Links near Cotkenzie, Mr. C. Stewart. ■ Leith 

 Links, Mr. J. T. Mackaij. Links near Aberlady, and Links near 

 St. Andrews, Maugh. Fl. July, Aug. 1/ . 

 Flowers very small, purplish red. Cal. remarkably large after flower- 

 ing, inflated, veined, and clustered, and often coloured, so as not 

 inaptly to represent the fruit from which it derives its specific name. 

 Mjuth of the Cal. at this time singularly contracted. 

 ^ ^ .(_ Standard of the Cor. persistent, scariose, enveloping the fruit.
