BRITISH WILD FLOWERS. 
very curious: it first resembles a ball with a little plume on the upper part, but when the seeds ripen, this upper 
part becomes depressed, and the case divides in the middle; the part with the plume then falls off, and the seeds 
which have been packed up into the smallest compass, gradually drop out. The flowers not only close before 
rain, but generally about two in the afternoon, and they open about seven in the morning. The plant is an 
annual, and it flowers in June and August. 
THE BLUE PIMPERNEL. (A. casrulea, Schreb.) 
This very pretty little plant is rare in England. The stem is upright, and the flowers, which are very small, 
are of a dark blue, with red in the centre. It is an annual, generally growing in corn-fields, and it flowers about 
July. 
THE BOG PIMPERNEL. (A. tenella, Lin.) 
This species is very different from the others. It has very small roundish leaves, and rather large pink 
flowers. It is a perennial, and it flowers in July and August, being generally found in wet peaty bogs.

THE CHICKWEED WINTER-GREEN. (Trientalis, Lin.) 
Lin. Syst. HEPTANDRIA MONOGYNIA. 
Description, &c. —This little plant, which is rare in England, and only found abundantly in some parts of 
the Highlands of Scotland, is very interesting in a botanical point of view, as all the parts of its flowers are in 
sevens, a number extremely rare in the parts of plants. It is the only British species of the Linnaean class 
Heptandria, from its seven stamens ; and its flowers have generally seven sepals to the calyx, and seven petals 
to the corolla. The leaves are also generally in a whorl of from four to seven. It has a creeping underground 
stem, sending up shoots from three to six inches high, which are entirely naked except at the apex, where they 
bear a whorl of leaves, with elegant white flowers, on long slender stalks, rising from their axils. The plant is a 
perennial, and it flowers in June. The origin of the name of Trientalis is very doubtful ; it is said to mean that 
the plant is only the third of a foot in height. 
Related to Primulacece. 
GENUS IX. 
THE COMMON BROOK-WEED. (Samolus, Lin.) 
Lin. Syst. PENTANDRIA MONOGYNIA. 
Description, &c. —The common Brook-weed or Water Pimpernel ( S. Valerandi , Lin.), has more the 
general appearance of a cruciferous plant than one of the Priinulaceas. It is a marsh plant, with a succulent 
stem, and very small white flowers. It is a perennial, and flowers in July. Having five stamens and a single 
style, it is placed in the Linnaean class and order Pentandria Monogynia. Some derive the name of Samolus, 
from Samos ; and others say that it is compounded of two Greek words, which signify to cure a hog, from this 
plant being used by the ancients as a remedy for the diseases of swine.
