tlrical, cal. teeth setaceous longer than the cor., leaflets nar- 

 row- obovate. Lightf. p. 406. E. B. /. 944. 



HAJB. Corn-fields and dry pastures, not unfrequent. Fl. July, Aug. Q . 



Stems 6 12 inches high, erect, branched. Flowers very minute. Re- 

 markable for the many subcylindrical soft hairy heads or spikes. 



7" Tr. scabrum (rough Trefoil), heads terminal and axillary ses- 

 sile ovate, eal. teeth unequal narrow- lanceolate rigid at length 

 recurved, leaflets obcordate serrulate. Lig/i/f. p. 407 . E. B.

HAB. Dry soils by the sea-shore, near Edinb., Dr. Parsons. Dry pas- 

 tures at Dunbar, by the sea. Mr. Borrer and Hook. Fl. June. Q . 



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 c'al. segments are narrow : in Tr. glomeratum the plant 

 is glabrous, the heads are round, the flowers reddish, the leaves 

 strongly toothed, the cal. segmen Abroad. The 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 teeth, leaflets obcordate nearly entire pubescent. 

 Lightf. p. 408. E. B. t. 1843. 



HAB. Diy pastures, as in Edinb. Park, abundantly, Lightf. Fl. June. 



0. 



From 4 8 or 10 inches long, more or less procumbent or reclined, 

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

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



Cal. remarkably inflated after flowering, 

 deciduous. 



Standard of the Cor. 



9. Tr.fragif'erum (Sir awlerry- headed Trefoil) , heads upon long 

 stalks roundish, cal. after flowering inflated membranaceous 

 pubescent two of the teeth setaceous reflexed, stems creeping, 

 leaflets obcordate serrated. E. B. t 1050. 



HAB. Moist pastures. Links near Cockenzie, Mr. C. Stewart. Leith 

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

 St. Andrews, Maugh. Fl. July, Aug. 11 . 



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. 

 Mouth of the Cal. at this time singularly contracted. 



-s--f--f- Standard of the Cor. persistent^ scariose, enveloping the fruit. 

 (Flowers yellow.) 



10. Tr. procumbent (Hop Trefoil], (i spikes oval imbricated, 

 standard deflexed persistent sulcated, steins procumbent, leaf- 

 lets obovate," Sw. Lightf. p. 409 (Tr. agratium). E. B.
