Amethystea. Amethystea Coerulea

A tender annual with pretty blue flowers, and a variety with white; grows about 1 1/2 foot high; not very common in gardens; in flower from July to October.

Ammobium

[From the Greek, meaning to live upon sand.}

Ammobinm alatum. - Winged Ammobium. - A pretty, half-hardy New Holland annual, with dry, white, involu-cral scales, like a Gnaphalium. The flowers, when gathered before they fully mature, retain their shape and brightness, and are fit companions for Helichrysums, Amaranths, and other everlasting flowers for winter ornaments. Height, two feet. The stems have a curious winged attachment their whole length.

Amsonia

[Named after a traveller, Mr. Charles Amson.]

Amsonia Tabernaemontana

Broad-leaved Amsonia, and has been called A. latifolia, but the name here given is the oldest. A hardy perennial, about two feet high, with leaves somewhat like those of the peach and pale-blue flowers in terminal clusters.

A. Salicifolia

Willow-leaved Amsonia, has narrower leaves. Both are easily cultivated native plants, which succeed in almost any soil, and flowers in June.

Anagallis. Pimpernel

. [From the Greek, to laugh; the name expressing the medicinal qualities of the plant; which, by removing obstructions from the liver, removed a cause of low spirits and despondency. So at least say Pliny and others.]

Anagallis arvensis - Pimpernel, or Poor man's weather glass, one of the Moras horologicae, opening its flowers regularly about eight minutes past eight o'clock in the latitude of England, and closing about three minutes past two o'clock. It also serves as an hygrometer, for, if rain fall, or there be much moisture in the atmospere, the flowers either do not open, or close up again. So says Loudon. It is a handsome trailing weed of England, and is found in some parts of this country.

Anagallis grandiflora carnea, A. lilacea and A. fruti-cosa, are pretty annuals.

Anchusa. Bugloss

[Derived from the Greek, meaning paint for the skin; one of the species having been used in early times to stain the skin.]

Anchusa Italica. - Italian Bugloss. - Is a tall-growing hardy perennial, with coarse, rough leaves, but bearing a multitude of small brilliant blue flowers all the season. There is another species with parti-colored red and purple flowers; and still another with red flowers. AU the species are tall-growing plants, from two to three feet high. Easy to cultivate and perfectly hardy, desirable only in large collections.
