seas of central Asia. Common on the British coasts. Fl. swmmer. 
VII. ANAGALLIS, PIMPERNEL. 
Procumbent or creeping herbs, with opposite leaves, and opposite 
axillary flowers on slender pedicels. Calyx deeply cleft into 5 narrow 
segments, Corolla 5-cleft, rotate or campanulate. Stamens 5. Capsule 
opening transversely by a circular fissure across the middle. 
A small genus, chiefly from the Mediterranean region and central 
Asia, with one South American species.

1. A. arvensis, Linn. (fig. 660). Common P., Shepherd’s or Poor 
Man’s Weather-glass.—A neat, much branched, procumbent annual, 6 
inches to near a foot long, with opposite, broadly ovate, sessile, and 
entire leaves. Pedicels considerably longer than the leaves, and rolled 
back as the capsule ripens. Calyx-divisions pointed. Corolla rotate, 
usually of a bright red within, but occasionally pale pink, or white, or 
bright blue. 
A very common weed of cultivation, in cornfields, gardens, waste 
places, &c., all over Europe and Russian Asia, except the extreme 
north, and has accompanied man in his migrations over a great part 
of the globe. J. the whole season. ‘The blue variety (A. cceerulea, Sm.) 
is as common in central and southern Europe as the red one, but with 
us it is rare. 
2. A. tenella, Linn. (fig. 661). Bog P.—A delicate, slender, creep- 
ing perennial, only a few inches long, with very small, orbicular, 
opposite leaves. Flowers very elegant, of a pale pink, on long slender 
pedicels. Segments of the calyx pointed but short. Corolla narrow 
campanulate, of a very delicate texture, and deeply 5-cleft. Stamens 
erect in the centre, with very woolly filaments. 
On wet, mossy banks, and bogs, chiefly along rivulets, throughout 
western Europe, extending eastward to north-western Germany, Tyrol, 
and here and there round the Mediterranean. Spread over the greater 
part of Britain, but chiefly in the west from Cornwall to Shetland, and 
in Ireland. Fl. summer.

VIII. CENTUNCULUS. CENTUNCLE. 
Small, slender annuals, with minute axillary flowers, differing from 
Anagallis in their alternate leaves, and in the parts of the flower being 
in fours instead of in fives. 
Besides our own species, the genus contains but very few, all from 
America, 
1. C. minimus, Linn. (fig. 662). Chaffweed.—Stem often under an 
inch and seldom 3 inches high, branched at the base only. Leaves 
ovate, 1 to 2 lines long. Flowers almost sessile, shorter than the leaves. 
Calyx-divisions linear. Corolla pink, very minute. Capsule opening 
transversely as in Anagallis. .
