Family Rosaceae

Trees , shrubs , or herbs, deciduous or evergreen . Stems erect , scandent , arching , prostrate , or creeping , armed or unarmed . Buds usually with several exposed scales , sometimes with only 2. Leaves alternate, rarely opposite, simple or compound ; stipules paired , free or adnate to petiole , rarely absent, persistent or deciduous; petiole usually 2-glandular apically; leaf blade often serrate at margin , rarely entire. Inflorescences various, from single flowers to umbellate , corymbose , racemose or cymose-paniculate. Flowers usually actinomorphic , bisexual , rarely unisexual and then plants dioecious. Hypanthium (formed from basal parts of sepals, petals, and stamens) free from or adnate to ovary, short or elongate . Sepals usually 5, rarely fewer or more, imbricate; epicalyx segments sometimes also present. Petals as many as sepals, inserted below margin of disk, free, imbricate, sometimes absent. Disk lining hypanthium, usually entire, rarely lobed . Stamens usually numerous , rarely few, always in a complete ring at margin of or above disk; filaments usually free, very rarely connate ; anthers small, didymous , rarely elongate, 2-locular. Carpels 1 to many, free, or ± connate and then adnate to inner surface of cupular receptacle; ovary inferior, semi-inferior, or superior; ovules usually 2 in each carpel, rarely 1 or several, anatropous , superposed . Styles as many as carpels, terminal , lateral , or basal, free or sometimes connate. Fruit a follicle, pome, achene, or drupe, rarely a capsule, naked or enclosed in persistent hypanthium and sometimes also by sepals. Seeds erect or pendulous, sometimes winged , usually exalbuminous , very rarely with thin endosperm; cotyledons mostly fleshy and convex abaxially, rarely folded or convolute.

Between 95 and 125 genera and 2825-3500 species: cosmopolitan , mostly in N temperate zone; 55 genera (two endemic) and 950 species (546 endemic) in China.

Many plants of this family are of economic importance and contribute to people s livelihoods. The Rosaceae contain a great number of fruit trees of temperate regions . The fruits contain vitamins, acids, and sugars and can be used both raw and for making preserves, jam, jelly, candy, various drinks, wine, vinegar, etc. The dried fruits of the genera

Amygdalus and Armeniaca are of high commercial value. Some plants in the genus Rosa containing essential oils or with a high vitamin content are used in industry . Rosaceae wood is used for making various articles, stems and roots are used for making tannin extract, and young leaves are used as a substitute for tea. Numerous species are used for medical purposes or are cultivated as ornamentals .

The Rosaceae are very well represented in China, with great economic and scientific importance. The Co-chairs of the Editorial Committee (Wu and Raven) here note that the patterns of relationship are complex and the group is taxonomically difficult. [1]

Genus Amelanchier

Shrubs or trees , deciduous; buds conspicuous , narrowly conical , with several scales . Leaves simple , petiolate , stipulate , venation camptodromous , margin entire or serrate. Racemes terminal ; bracts caducous . Hypanthium campanulate . Sepals 5, margin entire. Petals 5, white, oblong or lanceolate, slender. Stamens 10-20. Ovary inferior or semi-inferior, 2-5-loculed, with 2 ovules per locule, separated by a false partition from back of locule; styles 2-5, partly connate or free . Fruit a small berrylike pome, bluish black to dark purple, usually juicy and sweet, incompletely 4-10-loculed, with one seed in each locule, crowned by persistent , usually recurved sepals.

About 25 species: Asia, Europe, North America; two species (one endemic) in China.[2]
