''Calycanthus'' (sweetshrub)〔(''Flora of North America'': ''Calycanthus'' )〕〔(USDA Plants Profile: ''Calycanthus'' )〕 is a genus of flowering plants in the family Calycanthaceae, endemic to North America. The genus includes two to four species depending on taxonomic interpretation; two are accepted by the ''Flora of North America''. ==Description== ''Calycanthus'' plants are deciduous shrubs, growing tall and wide. The bright green leaves are opposite, entire, long and broad. The bark has a strong camphor smell that is released when stems are scraped.〔(''Calycanthus floridus''. ) from (Plants for a Future )〕 The smell remains strong on twigs that have been stored several years in a dry environment. The strongly scented flowers are produced from late spring through early autumn for ''Calycanthus occidentalis'', and April to July for ''Calycanthus floridus''.〔(Lady Bird Johnson Wildflower Center Native Plant Information Network-NPIN: ''Calycanthus occidentalis'' (Western spicebush) )〕 They are broad, with numerous dark red to burgundy to purplish brown tepals. Typical of the Calycanthaceae family, the flowers lack distinct sepals and petals, but instead have distinct spirals of tepals. The lotus-shaped flowers can resemble a small magnolia flower. They are pollinated by beetles in the Nitidulidae family.〔(Las Pilitas Horticulture database: Spice Bush−''Calycanthus occidentalis'' )〕 The fruit is an elliptic dry capsule 5–7 cm long, containing numerous seeds. 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「Calycanthus」の詳細全文を読む スポンサード リンク
