112 THE PEAFLOWEK TEIBE. [Tri folium. 



In dry pastures, on banks and waste places, in central and southern 

 Europe to the Caucasus, extending northward into southern Sweden. 

 Diffused over nearly the whole of England and southern Scotland, very 

 rare in Ireland. Fl. all summer. 



9. T. Bocconi, Savi. (fig. 253.) Boccone's 0. Very near T. striatum, 

 but the stems are erect or nearly so, 2 to 6 inches high ; the stipules 

 narrower ; the leaflets narrow-oblong, spathulate, or nearly linear ; the 

 flower-heads more oblong, usually 2 together at the summit of the stem, 

 and sometimes 1 or 2 besides, on short, lateral branches. Flowers 

 much like those of T. striatum, of a very pale colour, the calyx rather 

 less hairy. 



In dry pastures and waste places in southern Europe, and here and 

 there up western France. In Britain only on the Cornwall coast, near 

 the Lizard Point. Fl. summer. 



10. T. scabrmn, Linn. (fig. 254). Rough C. Very near T. striatum, 

 and not always easy to distinguish from it. Usually more procumbent 

 and less hairy, the leaflets not so broad, the flower-heads more in the 

 axils of the leaves, and the stipules of the floral leaves less prominent ; 

 but the chief distinction lies in the calyx, of which the teeth are broader, 

 more rigid, and usually spreading or recurved after flowering, giving 

 the plant a stiffer appearance. Flowers small and whitish. 



In dry pastures and waste places, in central and southern Europe to 

 the Caucasus, scarcely extending into northern Germany. In Britain, 

 chiefly near the sea, in England, eastern Ireland, and eastern Scotland, 

 but less common than T. striatum. Fl. all summer. 



11. T. strictum, Linn. (fig. 255). Upright C. An erect annual, 

 seldom 6 inches high, and perfectly glabrous. Stipules very broad and 

 thin. Leaflets narrow. Flower-heads solitary, or 2 or 3 on each 

 stem, pedunculate above the last leaves, small and globular. Flowers 

 very small. Calyx campanulate, the teeth subulate, quite glabrous, 

 and about the length of the corolla. Pod ovoid, generally 1 -seeded, 

 projecting from the calyx. 



In dry pastures and waste places, scattered over central and southern 

 Europe, from the Atlantic to Transylvania. In Britain, confined to the 

 Channel Islands and the coast about the Lizard Point. Fl. early summer. 



12. T. glomeratuxn. Linn. (fig. 256). Clustered C.A small, slender, 

 spreading annual, glabrous or nearly so. Stipules short, with a subulate 

 point. Leaflets broadly obovate. Flower-heads small, globular, closely 

 sessile in the axils of the leaves or at the ends of the branches. Calyx- 

 teeth short, broad, very pointed, and rigidly recurved as the pod ripens. 

 Corolla of a bright pink, very small, but longer than the calyx-teeth. 



On dry heaths, pastures, and waste places, very abundant in southern 

 Europe to the Caucasus, and extending more sparingly along western 

 France to the southern and eastern counties of England, and Wicklow 

 in Ireland. Fl. early summer. 



13. T. suffocatum, Linn. (fig. 257). Suffocated C.A very small 

 tufted annual, with procumbent stems often scarcely developed, and 

 seldom more than 2, or at most 3, inches long. Leaflets glabrous, obovate 

 on long, slender footstalks. Flowers small, closely sessile, in little 

 dense heads, crowded along the short stems, close to the ground. Calyx 

 thin, with fine recurved teeth ; the corolla very minute. 



In dry pastures and sandy or gravelly places, especially near the sea
