50 ENGLISH BOTANY. 
Section III.—TRIFOLIASTRUM. D.C. 
Flower-heads axillary and terminal, or all axillary, stalked or 
sessile, sub-globose or oblong. Flowers numerous, more or less 
distinctly stalked. Pedicels with bracts at the base. Calyx not 
becoming vesicular in fruit, without a callous or hairy ring in the 
throat ; teeth equal, or the upper ones longer. Corolla persistent, 
rarely deciduous, purple, rose, or white; standard often folded over 
the fruit, and retaining its form, but becoming scarious and striated. 
Pod sessile or slightly stipitate within the calyx, often exserted, 2- to 
6-seeded.

Puate CCCLVIII. 
Rootstock none. Stems numerous, slightly flexuous, prostrate 
or ascending, nearly simple or slightly branched, the central one 
elongate. Leaves rather shortly stalked; leaflets obovate, denti- 
culated, rounded at the apex ; veins very prominent, the lateral ones 
straight. Stipules adnate for less than half their length, with the 
free portion ovate, contracted into a long point; those which 
enclose the flower-heads dilated. Flower-heads axillary and ter- 
minal, sessile, solitary (or the terminal ones sometimes in pairs), 
not approximate, globular. Flowers sub-sessile. Calyx-tube oblong, 
10-ribbed, glabrous, open at the throat ; teeth ovate-acuminate, sub- 
spinescent, auricled at the base and reticulated, with a moderately 
thick central nerve, all nearly equal, shorter than the calyx-tube, 
at length spreading-recurved. Corolla longer than the calyx-teeth. 
Pod 2-seeded, shorter than the calyx-tube. Plant glabrous. 
On dry, gravelly, and sandy commons, pastures, and waste 
ground. Rather rare. It has been reported from the counties of 
Devon, Dorset, Hants, Kent, Surrey, Middlesex, Suffolk, Norfolk, 
Leicester, Somerset, Denbigh, Carmarthen, and Glamorgan; but 
the records of its occurrence in the West of England require to be 
confirmed. 
England. Annual. Early Summer. 
Stems slender, spreading in a circle, 2 to 12 inches long. Leaf- 
lets to 4 inch long, shaped like a boy’s kite, sharply toothed at 
the margins from the apex nearly to the base. Flower-heads rather 
distant, about + inch across, rather dense. Flowers sub-sessile, about 
¢ inch long, pale bluish-purple; standard becoming scarious, stri-
