Quince, shrub or small tree of the Asian genera Chaenomeles and Cydonia of the family Rosaceae (rose family). The common quince (Cydonia oblonga) is a spineless tree with edible fruits cultivated from ancient times in Asia and in the Mediterranean area, where it was early naturalized. Its pome fruit is similar to that of the related apple and pear but is very astringent, and hence it is used chiefly cooked in preserves; marmalade is said to have first been made from quince. As a commercial fruit tree, the quince is cultivated more widely in the temperate zone of Europe than in the United States, where it is grown chiefly in California and New York. It is often used as a rootstock for dwarf fruit trees, especially the pear. The flowering quinces (genus Chaenomeles) are cultivated as ornamental shrubs for their profuse, usually thorny branches and attractive scarlet, pink, or white flowers. The fruit is too small and hard to be of commercial value but is sometimes used locally. Best know

L oquat (lō`kwŏt), small ornamental evergreen tree (Eriobotrya japonica) and its fruit. It belongs to the family Rosaceae (rose family) and is probably indigenous to China. It has been grown from antiquity in Japan and N India and is cultivated also in Indochina, the Mediterranean region, and to some extent in the New World subtropics. The yellowish, oval fruits are borne in clusters and taste somewhat like apples or pears but are slightly tart. They are commonly eaten fresh but are used also for making jam, jelly, pie, and sauces. Sometimes the loquat is called Japanese medlar, probably because it somewhat resembles the medlar of Europe and Asia. The loquat is one of the few important fruit trees of the tropics belonging to the rose family. Loquat is classified in the division Magnoliophyta, class Magnoliopsida, order Rosales, family Rosaceae.

Apricot [Arabic from Lat.,=early ripe], tree, Prunus armeniaca, and its fruit, of the plum genus of the family Rosaceae (rose family), native to temperate Asia and long cultivated in Armenia. The fruit is used raw, canned, preserved, and dried. California is the chief place of cultivation in the United States, although by selecting suitable varieties the apricot can be grown in most regions where the peach is hardy. Apricots are used in the making of a cordial and also for apricot brandy. A number of apricot-plum hybrids, such as the plumcot, Pluot, and Aprium, have been developed. Apricots are classified in the division Magnoliophyta, class Magnoliopsida, order Rosales, family Rosaceae.

Cherry, name for several species of trees or shrubs of the genus Prunus (a few are sometimes classed as Padus) of the family Rosaceae (rose family) and for their fruits. The small, round red to black fruits are botanically designated drupes, or stone fruits, as are those of the closely related peach, apricot, and plum. The cherry is one of the most commonly grown home-orchard fruits. About 600 varieties are cultivated, practically all derived from two species—P. avium (sweet cherries) and P. cerasus (sour cherries). Both are believed to be native to Asia Minor and have long been cultivated; they were mentioned in the writings of the ancients. Sour cherries are hardier and more easily grown than sweet cherries and are mostly self-fertile, while many sweet cherries must be cross-pollinated to bear well. The fruit is popular raw, in preserves, and in pies; cherry cider and liqueurs are also made. Europe is the largest producing area. Several species of the flowering cherry, many native t

Pear, name for a fruit tree of the genus Pyrus of the family Rosaceae (rose family) and for its fruit, a pome. The common pear (P. communis) is one of the earliest cultivated of fruit trees, both in its native W Asia and in Europe. Most of the pear strains grown for their sweet and juicy fruit are varieties of P. communis or of its hybrids with other species of Pyrus—usually P. pyrifolia, known as the Japanese, Chinese, or sand pear and indigenous to China. The main use of the sand pear today is as a rootstock in pear orchards; the related quince is used for the same purpose. Pear strains with fruit of really good eating quality were not developed until the 18th and 19th cent. in N Europe, whence almost all the present successful varieties (e.g., the Bartlett and Seckel) grown in the United States (chiefly on the Pacific coast and in the Great Lakes area) were directly imported. European production is far greater—especially in Germany, France, and Switzerland, where much of the crop i

Figwort, common name for some members of the Scrophulariaceae, a family comprising chiefly herbs and small shrubs and distributed widely over all continents. The family includes a few climbing types and some parasitic and saprophytic forms. Common Species and Their Uses Among its many wildflowers are several European species that have been introduced to America and become thoroughly naturalized, e.g., the mulleins (genus Verbascum), the common speedwell (Veronica officinalis), and the butter-and-eggs (Linaria vulgaris). The common mullein (V. thapsus), also called flannel plant and torches, was formerly a favorite multipurpose medicinal plant; it is still occasionally used for domestic remedies, e.g., as a tea for coughs. Its large stalks are said to have been oiled and used for funeral torches in early times. The speedwells, of which several species are native to the United States, are also called veronica, supposedly because of a resemblance of the flower to the relic (see veronica

Rhizome (rī`zōm) or rootstock, fleshy, creeping underground stem by means of which certain plants propagate themselves. Buds that form at the joints produce new shoots. Thus if a rhizome is cut by a cultivating tool it does not die, as would a root, but becomes several plants instead of one, which explains why such weeds as Canada thistle and crabgrass are so hard to eradicate. Ginger, the common iris, trillium, and Solomon's-seal all have rhizomes. True arrowroot is starch from the rhizome of a West Indian plant. See perennial. Tuber , enlarged tip of a rhizome (underground stem) that stores food. Although much modified in structure, the tuber contains all the usual stem parts—bark, wood, pith, nodes, and internodes. The eyes of a potato tuber are nodes where sprouts appear, and they are arranged in the same spiral pattern characteristic of buds on an aerial stem.
