158 BRITISH BOTANY. 



Stems spreading and prostrate^ usually very short (2-6 inches 

 long) . Leaflets obovate, cuneate at the base, truncate or notched 

 at the apex, serrated, with sharply subvilate teeth ; stipules lan- 

 ceolate-subulate, entire. Flowers few {1-5), usnallj pedimculate. 

 Divisions of the calyx (teeth) nearly equal, longer than the tube- 

 Standard longer than the wings. Legume pubescent, linear,

 seeds (6-8). 



Dry, sandy, and gravelly places. Wandsworth Common.

Stems reclining and rooting, furrowed on one side, glabrous 

 or pubescent. Leaflets roundish-obovate, toothed, glabrous; 

 stipules membranous, entire, lanceolate, awned. Heads round, 

 subtended by scarious bracts. Peduncles axillary, much longer 

 than the leaves. Calyx pubescent, with silky hairs, and with 

 linear-subulate divisions, inflated, membranous and reticulate in 

 fruit.

T. resupinatum, L. Reversed Trefoil. — e.b.s. 2789. l.b.s. List 

 of Excluded Sp. 



A. 3 ? Lat. 51°. Alt. 0-50 yds. 



Root annual. Stem slender, prostrate or ascending. Leaflets 

 obovate, rounded, toothed, with lanceolate, elongate stipules, 

 ovate at the base, lanceolate-subulate above. Peduncles about 

 as long as the leaves. Flowers in rather lax, hemispherical 

 heads, purplish, twice as long as the calyx. Fruit in strawberry- 

 like clusters, formed by the inflated calyx. 



At Wandsworth Steam-boat Pier. Annual ; June-Sept, 



This species may readily be known by its elegant purplish 

 flowers, and when in fruit by its inflated calyxes, forming a glo- 

 bular head like that of T. fragiferum.

 Leaflets obovate-toothed. Heads nearly sessile. Flowers ro-
