''Celtis tenuifolia'', the Dwarf Hackberry or Georgia Hackberry is a shrub or small tree 2 to 12 meters high. It is native to eastern North America, but is very uncommon north of the Ohio River.〔(【引用サイトリンク】 Celtis Tenuifolia Range Map )〕 In Canada, dwarf hackberry is designated as threatened and protected under Canada's Species at Risk Act.〔COSEWIC. 2003. COSEWIC assessment and update status report on the dwarf hackberry Celtis tenuifolia in Canada. Committee on the Status of Endangered Wildlife in Canada. Ottawa. vi + 15 pp. (www.sararegistry.gc.ca/status/status_e.cfm)〕 ==Characteristics== The leaves are alternate, simple, blades 5 to 7 centimeters long, and 2 to 3.5 centimeters in width, shallowly toothed, and finely hairy. The winter buds are brown and hairy, similar to those of other hackberries, but smaller, only 1 to 2 centimeters long. Terminal buds absent. Flowers are monecious and unisexual, occurring either solitarily or in small clusters. This species is wind-pollinated and appears to be self-compatible. The fruit is a berry-like drupe, 5 to 8 millimeters in diameter, consisting of a single stone encased within a thin, sweet mesocarp. From green, it becomes a light orange, then a dark red, then purplish-brown. This edible mesocarp is composed of a smooth outer crust and a pulpy yellow inside. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Celtis tenuifolia」の詳細全文を読む スポンサード リンク
