in southern Europe to the Caucasus, extending up western France to the 
shores of the Channel. Rare in England, on the southern coasts, extend- 
ing eastward up to Norfolk, and westward to Anglesea; not recorded 
from Ireland, but perhaps overlooked. Fl. spring or early summer. 
14. T. resupinatum, Linn. (fig. 258). Reversed C.—A glabrous 
annual, with numerous stems, leafy and tufted at the base, lengthened out 
to afoot or more. Stipules rather broad, with narrow points. Flower- 
heads small, on short axillary peduncles. Calyx glabrous or hairy on the 
upper side, the teeth short, but after flowering the upper part becomes 
very much inflated, arched, membranous and veined, with the 2 upper 
teeth at the top, the 3 lower ones remaining at the base of the inflated 
part. Corolla small, pink, the sides of the standard turned outwards 
instead of inwards as in other T'rifolia. 
In meadows and pastures, especially near the sea, in southern Europe 
to the Caucasus, and up western France to the shores of the Channel. 
Not indigenous in Britain, but has occasionally appeared in some of the 
southern counties of England. J. spring and early summer. 
15. T. subterraneum, Linn. (fig. 259). Subterranean C.—A small, 
_ prostrate annual, more or less clothed with long spreading hairs; the 
stems usually short and tufted, but occasionally lengthened out to 6 or 
8inches. Stipules broad. Leaflets obovate, on long leafstalks. Flowers 
white or pale pink, long in proportion to the plant, 2 or 3 together on 
axillary peduncles, which lengthen considerably after flowering, and 
turn down almost into the ground; the fruiting calyx then turns back 
upon the peduncle, and is usually surrounded by short thick fibres, each 
with 5 spreading, subulate teeth, showing that they are undeveloped 
calyxes. 
In dry, gravelly or sandy pastures, common in southern Europe to the 
Caucasus, and up western France to the Channel. Abundant in many 
parts of southern and central England, and in co. Wicklow in Ireland, 
but not in the north, nor in Scotland. fv. spring and early summer. 
16. T. fragiferum, Linn. (fig. 260). Strawberry C.—The perennial 
stock, creeping stems, foliage, and peduncles are those of 7’. repens, 
but the flowers are closely sessile in the head, surrounded by an involucre 
of lobed bracts as long as the calyx-tubes, and the calyx, after flowering, 
_ becomes much inflated, thin, and reticulate, with short fine teeth ; the 
flower-head is then very compact, half an inch or more in diameter, and 
often assumes a pink tint, so as to have been compared to a strawberry. 
Corolla small and red. 
In rather dry meadows and pastures, common in Europe and central and 
Russian Asia, penetrating far into Scandinavia. Frequent in England, 
local in Ireland and Scotland. Fl. summer and autumn. 
17. T. repens, Linn. (fig. 261). White or Dutch C.—A glabrous or 
slightly hairy perennial, the stems creeping and rooting at the nodes. 
Stipules small. Leaflets obovate, distinctly toothed, and usually bearing 
a mark in the centre, which has been compared to a horseshoe, the leaf- 
stalks often very long. Peduncles axillary, long, and erect, bearing a 
globular head, or rather umbel, of white flowers, often tinged with pink ; 
the pedicels, after lowering, more or less elongated and recurved. Calyx- 
teeth scarcely so long as the tube, the lowest one usually the shortest. 
Pod containing 2 to 4 seeds, usually protruding from the calyx, but 
enclosed in the withered corolla,
