"A genus of palms, the most important species of which is the common Date Palm, the Palm Tree of Scripture, a native of the northern half of Aftica, the south-west of Asia, and some parts of India, and which has also been brought into cultivation in the south of Europe, and might certainly be intruduced with advantage into the south of the United States, and many warm parts of America and Australia." — Chambers' Encyclopedia, 1875

Date Palm

A date palm.

An illustration of a portion of a date palm leaf. The Date Palm (Phoenix dactylifera) is a palm in the genus Phoenix, extensively cultivated for its edible fruit. Due to its long history of cultivation for fruit, its exact native distribution is unknown, but probably originated somewhere in the desert oases of northern Africa, and perhaps also southwest Asia. It is a medium-sized tree, 15–25 m tall, often clumped with several trunks from a single root system, but often growing singly as well. The leaves are pinnate, 3–5 m long, with spines on the petiole and about 150 leaflets; the leaflets are 30 cm long and 2 cm broad. The full span of the crown ranges from 6–10 m.

Date-tree

The genus of palms which bear dates.

An illustration of the fruit of a date palm, a date.  The fruit is a drupe known as a date. They are oval-cylindrical, 3–7 cm long, and 2–3 cm diameter, and when unripe, range from bright red to bright yellow in colour, depending on variety. Dates contain a single seed about 2–2.5 cm long and 6–8 mm thick. Three main cultivar groups of date exist; soft (e.g. 'Barhee', 'Halawy', 'Khadrawy', 'Medjool'), semi-dry (e.g. 'Dayri', 'Deglet Noor', 'Zahidi'), and dry (e.g. 'Thoory'). The type of fruit depends on the glucose, fructose and sucrose content.

Dogwood flower

This is the single flower of the dogwood, Cornus florida, (Keeler, 1915).

Leaves - simple, alternate (often crowded at the ends of the branches); edge entire. Outline - broadly oval or egg-shape or reverse egg-shape. Apex - pointed. Base - slightly pointed. Leaf/Stem - one inch long or more. Leaf - about three to four inches long, sometimes yellowish-green; smooth above; whitish beneath, and slightly rough between the prominent curved ribs, seldom entirely flat, usually in clusters at the ends of the branches. Bark - of the branches, smooth, yellowish-green, with whitish streaks. Flowers - yellowish in loose flat clusters. June. Fruit - very dark blue when ripe, on reddish stems. August. Found - in low rich woods and along streams, from New Brunswick through the Northern States, and southward along the Alleghany Mountains to Northern Georgia and Alabama. General Information - A small tree or shrub, ten to twenty feet high, with wide-spreading branches and flattish top. A "Shaker Medicine" is made from its bitter bark. Cornus, from a Greek word meaning horn, because of the hardness of the wood.

Leaves - simple; opposite; edge entire. Outline - egg-shape, or often broad oval, or reverse egg-shape. Apex - pointed, often taper-pointed. Base - pointed and usually slightly unequal. Leaf/Stem - short (about one half inch). Leaf - three to five inches long; smooth above; pale and nearly smooth beneath; with the whitish ribs very distinct and curved. Bark - of trunk, blackish and rough, with short, broken ridges. The bark, especially of the roots, is very bitter and is used as a tonic. Flowers - The real flowers are greenish-yellow, in a small rounded bunch; but this bunch is surrounded by four large, petal-like leaves, white and often tinged with pink, more than an inch in length, reverse egg-shaped, and ending in a hard, abruptly turned point. The appearance is of a single large flower. The tree blossoms in May before the leaves are fully set. Fruit - The "Flower" is succeeded by a bunch of oval berries that turn bright red as they ripen, making the tree in the autumn, with its richly changing foliage, nearly as attractive as in the spring. Found - in rich woods, from New England to Minnesota, and southward to Florida and Texas. It is very common, especially at the South. General Information - A finely shaped, rather flat-branching tree, usually twelve to thirty feet high, but dwindling, northward, to the dimensions of a shrub; one of the most ornamental of all our native flowering trees. Its character throughout the extent of its range would seem to warrant the recognition of its blossom as the "national flower." Cornus, from a Greek word meaning horn, because of the hardness of the wood.

General Information - A tree sixty to eighty feet high.

Dracaena is a genus of about 40 species of trees and succulent shrubs classified in the family Ruscaceae in the APG II system, or, according to some treatments, separated (sometimes with Cordyline) into a family of their own, Dracaenaceae or in the Agavaceae. The majority of the species are native in Africa, with a few in southern Asia and one in tropical Central America. The segregate genus Pleomele is now generally included in Dracaena. The genus Sanseviera is closely related, and has recently been synonymized under Dracaena in the Kubitzki system.
