1, C.lutetiana, Linn. (fig. 352). Common Circe@a, LEnchanter’s 
Nightshade.—Stems erect or shortly decumbent, and rooting at the base, 
1 to 14 feet high, and, as well as the leaves and racemes, more or less 
clothed with very short whitish hairs. Leaves on rather long stalks, 
broadly ovate or heart-shaped, 2 to 3 inches long, rather coarsely toothed, 
of a thin texture. Flowers white or pink, in elegant, slightly branched, 
leafless, terminal racemes. Pedicels about 2 lines long, turned down after 
flowering. Capsule small, . aes covered with stiff, hooked hairs, 
forming a small burr. Seeds 2 
In woods and shady situations, throughout Europe and central and 
Russian Asia, except the extreme north, andin North America, Abundant 
in England and Ireland, rarer in Scotland, but extending to Aberdeenshire. 
Fl, summer. 
2, C. alpina, Linn. (fig. 353). Alpine Circea.—Closely resembles the 
common species, of which it may be a mountain variety, but is smaller in 
all its parts, and usually quite glabrous, except the fruit. It is seldom 
above 6 inches high ; the leaves are thinner, and often glossy ; the capsules 
smaller, less hairy, much narrower, and usually contain only a single seed, 
owing to the almost constant abortion of one of the cells. 
In woods, and stony places, chiefly in mountain districts, in Europe and 
all across Russian Asia, often ascending to great altitudes, and penetrating 
further northward than C. lutetiana, but apparently not an Arctic plant. 
Abundant in Scotland, extending into the midland counties of England, 
but disappearing in the south; in Ireland it is both in the north and in 
Cork county. #7. summer. <A larger variety, or hybrid, has sometimes 
been described as a distinct species, under the name of C. intermedia, 
Ehrh,, a name also occasionally given to smaller states of C. lutetiana. 
XXVIII. LYTHRARIEA. THE LYTHRUM FAMILY. 
_ _Herbs, or, in some exotic genera, shrubs or trees, with leaves 
mostly (at least the lower ones) opposite, entire, and without 
stipules; the flowers either axillary or forming terminal 
racemes or spikes, more or less leafy at the base. Calyx free, 
tubular or campanulate, with as many, or twice as many, teeth 
as there are petals. Petals 4, 5, or sometimes more, rarely 
deficient, inserted at the top of the tube of the calyx, crumpled 
in the bud. Stamens equal to or double the number of the 
petals (or, in some exotic genera, indefinite), inserted in the 
tube of the calyx, often lower down than the petals. Style 
single. Ovary free from the calyx, but generally enclosed 
within its tube, divided into 2 or more cells, each with several 
ovules. Capsule of a thin texture, sometimes becoming 1-celled 
by the drying up of the partition, containing several small seeds 
without albumen.
