 much branched." — Br. Fl. p. 101. E. B. i. 944. 



In dry, barren, sandy fields and pastures, on banks and waste ground by the 

 sea ; frequent. -Fi. June — August. 0. 



E. Med.— On the Dover, Kyde. Plentiful and very luxuriant at the foot of 

 the clifl's in Sandown bay, on the debris of the green sandstone. On St. Helen's 

 S]iit. 



Root tough, tapering, with several long slender fibres running far into the sandy 

 ground. Stems round, numerous, erect or ascending, sometimes procumbent, 

 clothed like the rest of the plant with copious gray pubescence. Leaves on short 

 stalks, of 3 narrow, obovato-lanceolate, sessile leaflets, abrupt or truncate at the 

 tip, with a minute point and a few obscure serratures. Stipules small, strongly 

 ribbed with green or purple, with long spreading points. Heads of flowers termi- 

 nal, cylindrical, very obtuse, grayish white with a. bluish tinge, extremely soft, 

 scarcely an inch long. Calyx minute, the tube ovate, 10-ribbed, and like the 

 long, flexible, spreading, setaceous teeth covered with flue white hairs. Corolla 

 much shorter than the calyx-teeth, very small, cream-coloured, ovate, incumbent, 

 the sides deflexed, with a long, broad, curved claw. Legumes very minute, yel- 

 lowish, membranous and wrinkled, nearly orbicular, tipped with the style. Seed 

 solitary, filling the pod, greenish yellow, nearly globular, smooth. 



5. T. striatum, L. Soft Knotted Trefoil. Downy, heads of 

 flowers terminal and axillary ovate subsolitary sessile, calyx pro- 

 minently 10-ribbed in seed ventricose, its teeth subulate nearly 

 erect rigid, leaflets obcordate subdenticulate at the summit with 

 numerous close not prominent veins running straight to the mar- 

 gin. Br. Fl. p. 101. E. B. t. 1843.

E. Med. — On the Dover, Ryde. [On St. Helen's spit and in Sandown bay, 

 A. G. More, Esq., Edrs.] 



Whole herb downy with copious, long, simple, spreading hairs. Root tough, 

 whitish and tapering, scarcely branched but mostly emitting many slender tuber- 

 cular fibres. Stems numerous, much branched from the base or nearly simple, 

 round, solid, purplish above, a little rigid, 3 inches and upwards in length, usu- 

 ally procumbent or prostrate, rarely in a variety mentioned by Mr. Leighlon (Fl. 

 of Shrops. p. 363) erect or ascending, for the most part spreading in a circular 

 form. Leaves distant, alternate, inferior on long, the superior on much shorter 

 half-rounded petioles grooved above, the uppermost leaf subtending the terminal 

 flower-heads, very shortly stalked ; leaflets silky, grayish green, on very short 

 stalks, or very nearly sessile ; those of the lower leaves obcordato-obovate or even 

 rotundato-obovate ; of the upper obovate or obovate-elliptical, cuneate at the base 

 and pointed, at other times shaped like the inferior leaflets ; all, as Sir W. Hooker 

 remarks, nearly entire, being only obscurely sinuato-denticulate along their upper 

 margins, the veins, as Koch observes, of equal thickness throughout, very nume- 

 rous, close, not prominent, and running in nearly straight lines to their marginal 

 termination. Stipules large, membranaceous, ribbed, ovate or oblong, adnate to 

 the petiole and amplexicaul, with subulate sometimes leafy points, those beneath 

 the flower-heads very broad and concave. Heads many-flowered, axillary and 

 terminal, solitary or in pairs (the second smaller and placed laterally), sessile, 

 ovate or roundish ovate, often (at least in seed) subconical. Flowers small, erect, 

 quite sessile and ebracteate. Calyx tubular, somewhat elliptical, a little gibbous 

 in front, much swollen or ventricose in seed, prominently 10-ribbed, the ribs red 

 or greenish, when in fruit foi-ming very broad convex ridges with deep intermedi- 

 ate furrows ; teeth erect, lanceolato-triangular, scarcely half the length of the 

 tube, green or purplish, single-ribbed, rigid and unequal, the 3 lowermost rather
