42 ENGLISH BOTANY. 



Very local ; probably confined to the counties of Essex, Cambridge, 

 Herts, Suffolk, and Norfolk. 



England. Perennial. Summer and Autumn. 



Uootstock many-headed, producing tufts of long-stalked leaves 

 and flowering stems, which are 9 to 18 inches high, erect, with a 

 slight curvature at the base. Leaflets ^ to 1 inch long, those of 

 lower leaves obovate, obcordate, becoming more oval or elliptical 

 and entire on the apex, as they are placed higher on the stem. 

 Stipules with long slender triangular points. The uppermost of 

 the alternate leaves remote from the pair of opposite ones : these 

 latter are generally considerably smaller in size, very shortly 

 stalked, and with the stij^ules broader. Elower-heads ^ to 1^ inch 

 above the involucre, f to 1^ inch in diameter. Elowers f inch 

 long, oclireous. The calyx-teeth erect when in flower, but spreading 

 when in fruit, especially the lower one, which becomes reflexed. 

 Pod longitudinally striate, opening by an operculum. Seed ovoid, 

 smooth. Stem and petioles thickly clothed with spreading tawny 

 hairs, the leaves with adpressed hairs. 



This plant has much the habit of T. pratense, but the stipules 

 are more like those of T. medium. The pale-yellow flowers form a 

 conspicuous distinction from the common states of both these 

 plants, but one on which implicit confidence cannot be placed, as T. 

 pratense sometimes has flowers of that colour. The calyx-teeth 

 are decidedly broader at the base, and tapering gradually in a 

 triangular shape, and much more strongly nerved than in either 

 of the two preceding species. 



SuJphiir-coloured Trefoil. 



French, Trejle Jauiidtre. German, Blassgelber Klee. 



This species has been recommended to the experimental agriculturist as a sub- 

 stitute for others in certain soils and situations ; but it has met with no favour, and is 

 not often grown at all. 



SPECIES v.— TRIPOLI UM MARITIMUM. Iluds. 

 Plate CCCL. 



Rootstock none. Stems several, ascending, branched. Leaflets 

 oblaneeolate, entire. Stipules herbaceous, with few nerves which 

 do not anastomose, adnate for less than half their length, with 

 the free portion elongated, linear-triangular. Uppermost leaves 

 opposite, shortly stalked, a little below the flower-heads, with 

 slightly dilated stipules. Elower - heads stalked, terminating 

 the stem and branches, globose-ovoid, becoming ovate-ovoid in 

 fruit. Calyx-tube 10-ribbcd, sub-glabrous, the throat with lateral 

 callosities nearly closing its mouth; teeth rather shorter than
