other, and the heads look much less compact than those of the 

 StrawbeiTy Trefoil. The flowers are about ^ inch long, pale bluish- 

 purple. Pod extremely short, £;lobidar, 2-seeded. 



The curious twist of the corolla, which brings the standard below 

 the keel, at once distinguishes this plant when in flower from all the 

 other British species, while by the reticulated and inflated calyces 

 with their apices all separate from each other, it may be equally 

 well known in fruit. 



Reversed-Jloicered Trefoil.

Section V.— CHRONOSEMITJM. D. 0. 



Flower-heads axillary and terminal or all axillary, sub-globose, 

 becoming ovoid. Flowers sessile or shortly stalked. Pedicels with 

 bracts at the base. Calyx not becoming vesicular in fruit, without 

 a callous or hairy ring in the throat ; the teeth equal, or the 2 

 upper ones shorter, remaining unchanged in fruit. Corolla yellow ; 

 standard becoming enlarged and scarious, folded (at least at the 

 base), and bent down at the tip over the fruit. Pod stalked within 

 the calyx, exserted, 1-seeded, more rarely 2-seeded. Leaves fre- 

 quently pinnately trifoliate.

Rootstock none. Stems several, slender, wiry, erect or ascend- 

 ing, or pi'ocumbent, branched. Leaves shortly stalked, pinnately 

 trifoliate ; leaflets obovate or oblanceolate, usually truncate or 

 emarginate at the apex, finely denticulate in the upper portion. 

 Stipules adnate for about half their length, half-ovate, rounded at 

 the base ; the free portion deltoid, triangular-acute, entire. Flower- 

 heads axillary, on stalks exceeding their own lengtb, and usually 

 (but not always) longer than the leaves from which they spring, 

 globular, at length ovoid or oblong, very dense, many-flowered. 

 Flowers on pedicels shorter than the calyx-tube, at length reflexed. 

 Calyx-tube bell-shaped ; upper teeth triangular, shorter than the 

 tube, the 3 lower ones lanceolate and exceeding it, unaltered in 

 fruit. Corolla longer than the calyx ; standard broadly obovate,
