United States Department of Agriculture plants profile, accessed Oct. 18th, 2011. )〕 == Description == Dewberry is known as a sub-shrub or herbaceous perennial (Kartesz 2011). The trailing stems (stolons) are in length, and the upright petioles are usually less than 20 cm (8 inches) tall. They differ from larger shrubby species in the genus in that the only upright part is herbaceous and only lightly speckled with fine hairs (hence the specific epithet "pubescens"), as opposed to the woody stems and larger prickles that cover many other species of ''Rubus''〔Johnson, D., L. Kershaw, and A. Mackinnon. 1999. Plants of the Western Boreal Forest and Aspen Parkland: Including Alberta, Saskatchewan And Manitoba. Lone Pine Publishing, Edmonton, Alberta.〕〔(Flora of North America, ''Rubus pubescens'' Rafinesque, 1811. Dwarf red blackberry or raspberry or red raspberry, ronce pubescente )〕 Leaves are compound with three more or less sessile (stalk-less), diamond-shaped leaflets. The middle leaflet is the largest, and most symmetrical, while the two side leaflets are wider below the midrib; all leaflets have toothed margins.〔 With the exception of the trailing stems, all parts of the plant are shed in the fall.〔 Flowers have five white petals, often curled backwards, and the yellowish anthers give the center an appearance of yellow and black speckles. Flowering typically occurs between late May and late June, depending on the locality, but occasional flowers can be seen from early May through August. Flowers usually produce a single shiny red fruit, in the form of a compound drupe (several tiny berries attached to a central receptacle), in early July. Like a blackberry, the fruit does not easily separate from its receptacle.〔 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「Rubus pubescens」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
