Trifolium. | XXV. PAPILIONACES. 113 
stem, pedunculate above the last leaves, small and globular. Flowers very 
small, Calyx campanulate, the teeth subulate, quite glabrous, and about 
the length of the corolla. Pod ovoid, generally 1-seeded, projecting from 
the calyx. 
In dry pastures and waste places, scattered over central and southern 
Europe, from the Atlantic to Transylvania. In Britain, confined to the 
Channel Islands and the Cornwall coast about the Lizard Point. FV. early 
summer. 
11. T. glomeratum, Linn. (fig. 255). Clustered Clover.—A small, 
slender, spreading annual, glabrous or nearly so. Stipules short, with a 
subulate point. Leaflets broadly obovate. Flower-heads small, globular, 
closely sessile in the axils of the leaves or at the ends of the branches. 
Calyx-teeth short, broad, very pointed, and rigidly recurved as the pod 
ripens. Corolla of a bright pink, very small, although longer than the 
calyx-teeth., 
On dry heaths, pastures, and waste places, very abundant in southern 
Europe to the Caucasus, and extending more sparingly along western 
France to the southern and eastern counties of England, and Wicklow in 
Ireland. Fl. early summer. 
12. T.suffocatum, Linn. (fig. 256). Suffocated Clover.—A very 
small tufted annual, with procumbent stems often scarcely developed, and 
seldom more than 2, or at most 3, inches long. Leaflets glabrous, obovate, 
on long, slender footstalks. Flowers small, closely sessile, in little dense 
heads, crowded along the short stems, close to the ground. Calyx thin, 
with fine recurved teeth ; the corolla very minute. 
In dry pastures and sandy or gravelly places, especially near the sea, in 
southern Europe to the Caucasus, extending up western France to the 
shores of the Channel. Rare in England, on the southern coasts, extending 
eastward up to Norfolk, and westward to Anglesea; not recorded from 
Ireland, but perhaps overlooked from its small size. Fl. spring or early 
summer. 
13, T. resupinatum, Linn. (fig. 257). Reversed Clover.—A glabrous 
annual, with numerous stems, leafy and tufted at the base, lengthened out 
to a foot 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 standard turned outwards instead of in- 
wards as in other Trifolia. 
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 someof the southern 
counties of England. 1. spring and early summer. 
14, T.subterraneum, Linn. (fig. 258). Subterranean Clover.—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 
8 inches. 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
