below the petals, variable in number. Capsule covered by the tube of 
the cal^x, 1-celled, placenta central. — (G. Don.) 
Essential Character, — Calyx tubular, ribbed, the sinuses between 
the lobes sometimes lengthened out into the other lobes. Petals 4 — 6, 
inserted into the tube of the calyx. Stamens inserted in the tube 
Description, &c. — The OTieT*Li/thracece contains several interesting plants, and among others, the Henna 
{Laicsonta inermis), so much used hy ladies in the East, the Lagerstroemias, or Pride of India, and the plant 
supposed by some to be the Rosewood of commerce, PhysocaJymna floribunda. The only genera containing 
annual flowers are Lythrum and Cuphea. The annuals in the first genus are wild British plants, and only 
those belonging to the genus Cuphea are cultivated in gardens. Even these plants are by no means beautiful, as 
they have all that peculiarly dark reddish and yet blackish purple, which has made the name of the order be 
derived from the word lythron, black blood.

Generic Cuaricter. — Calyx tubular, 12-toothed, Petals 6 — 7, unequal. Stamens 11 — 14, rarely 6 — 7, unequal, inserted in the orifice of the 
calyx. Capsule 1 — 2-celled, — (G, Don.') 
Description, &c, — The plants composing the genus Cuphea were separated from those forming the genus 
Lythrum, chiefly because the former have a tubular calyx and unequal petals, while the latter have not a tubular 
calyx, and the petals are equal. There is likewise a difference in the stamens, and in the capsule.

Description, &c. — An erect plant, growing from a foot to eighteen inches high, with a dark purple stem, and 
pale dull purple flowers. The stem is branched, and the whole plant is covered with clammy hairs. The flowers 
begin to appear when the plant is not above six inches high, and as it continues growing, the flowers continue 
expanding. It is found wild in America, from Brazil to Pennsylvania, in humid shady places. It was introduced 
m 1 776. The seeds are generally raised on a hotbed, and planted out into a moist shady border in June ; or 
they may be sown in the open air in April.
