''Pilostyles'' is a genus of flowering plants currently placed in the family Apodanthaceae. It was formerly placed in the Rafflesiaceae. It includes several species of parasitic plants that live inside the stems of other plants and produce tiny flowers that burst through the surface of the host plants' tissue. Plants of this genus are sometimes referred to as stemsuckers.〔(USDA Plants Profile: ''Pilostyles'' )〕 ''Pilostyles'' are specialized parasites of woody-stemmed legumes.〔Gomes, A. L. & G. W. Fernandes. (1994). (Influence of parasitism by ''Pilostyles ingae'' (Rafflesiaceae) on its host plant, ''Mimosa naguirei'' (Leguminosae) ). ''Annals of Botany'' 74 205-8.〕 There are about 20 species.〔Armstrong, W. (Southern California's Most Unusual Wildflower )〕 They are perennial herbs that lack roots and chlorophyll, as they obtain water and nutrients from their hosts.〔 The plants themselves are only a few millimeters wide and live within the host plant tissue, becoming externally visible only when the flowers emerge.〔 The flowers are two or three millimeters wide and in some species each female flower can produce over 100 seeds, which are minute.〔 Species include: *''Pilostyles blanchetii'' *''Pilostyles hamiltonii'' *''Pilostyles haussknechtii'' *''Pilostyles ingae'' *''Pilostyles strawiaskii'' *''Pilostyles thurberi'' ==References== 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「Pilostyles」の詳細全文を読む スポンサード リンク
