 Native of several parts of Europe, as Germany, Switzer-

 Algiers, in Barbary ; also of Britain, where it is found occa- 

 sionally on chalky ground, or in dry sandy fields that lie 

 over a calcareous soil, flowering in May and June, and then 

 soon dries up, and is blown about, scattering its seeds against 

 the autumnal rains, when they produce young plants, which 

 flower in the following spring. It occurs between Northfleet 

 and Gravesend ; near Chatham, and in the isle of Shepey ; 

 about Croydon, in Surry ; on Newmarket Heath ; about Chip- 

 penham and Gamlingay, in Cambridgeshire ; and near Cam-

 reflexed, veined. Root annual, small, fibrous, with oval fleshy 

 knobs ; corolla pale red or rose-coloured. It flowers about mid- 

 summer. Native of Spain, Italy, and Barbary, about Algiers.

 generally found in a moist gravelly soil. 



35. Trifolujni Striatum ; Soft Knotty Trefoil. Heads ses- 

 sile, lateral, and terminating, ovate ; calices elliptic, hirsute, 

 grooved ; teeth setaceous ; leaves downy. Root annual ; co- 

 rolla scarcely the length of the calix, pale purple. It flow- 

 ers in June Native of Britain, Germany, France, Spain,

36. Trifolium Suffocatum ; Suffocated Trefoil. Heads 

 sessile, lateral, roundish, smoothish ; calicine teeth lanceo- 

 late, acute, recurved, longer than the corolJa. Root annual, 

 tapering, without any tuberous swellings; flowers in sessile 

 axillary round heads; body of the calix a little hairy; teeth 

 bent back, broad, acute, scarcely enlarged after flowering; 

 corolla much shorter than the calix. The exclusion of light 

 often renders the petals whitish, otherwise they are rose- 

 coloured. It grows in the loose blowing sand of the sea- 



shore, beneath which its stems and flowers are often entirely 

 buried, the leaves only peeping above the surface; to this 

 the trivial name alludes, and hence perhaps it has been over- 

 looked as some common species not yet in flower. -Native 

 of Sicily and England. It flowers here in June and July, 

 and is found on the beach at Lowestoff, Yarmouth, and 

 Landguard fort near Harwich. 



37. Trifolium Alexandrinum ; Egyptian Trefoil. Heads

 roundish; calices inflated, two-toothed, reflexed; stem creep- 

 ing. Root perennial, fibrous, with little 'tubers: corolla pur- 

 ple ; banner longer than the wings, flat, and streaked with 

 rose-coloured lines. The singular strawberry-like appear- 

 ance of the heads, arising from the inflation of the calix after 

 flowering, strikingly distinguishes this from the thirteenth 

 species, to which in its general habit it is nearly allied: the 

 whole plant also of this species is smaller, and it usually 

 occurs in moist situations. Native of all parts of Europe, 

 flowering in July and August.
