''Physaria'' is a genus of flowering plants in the mustard family. Many species are known generally as twinpods, bladderpods, or lesquerella. They are native to the Americas, with many species endemic to western North America. They are densely hairy perennial herbs often growing prostrate or decumbent, along the ground in patches or clumps. They bear inflorescences of bright yellow flowers. The fruit is often notched deeply, dividing into twin sections, giving the genus its common name. Bladderpod oil is extracted from the seeds of ''Physaria fendleri'' and certain other species in the genus.〔() U.S. Fish and Wildlife Service: Missouri Bladderpod 5-Year Review (2008)〕 Many of species of ''Physaria'' were formerly included in the now-defunct genus ''Lesquerella''. Species include: *''Physaria acutifolia''—Sharpleaf twinpod *''Physaria alpestris''—Washington twinpod *''Physaria alpina''—Avery Peak twinpod *''Physaria argyraea''—Silver bladderpod *''Physaria bellii''—Front Range twinpod *''Physaria brassicoides''—Double twinpod *''Physaria chambersii''—Chambers' twinpod *''Physaria condensata''—Tufted twinpod *''Physaria congesta'' —Dudley Bluffs bladderpod *''Physaria didymocarpa''—Common twinpod *''Physaria fendleri''—Fendler's bladderpod *''Physaria filiformis''—Missouri bladderpod *''Physaria floribunda''—Pointtip twinpod *''Physaria fremontii''—Fremont's bladderpod *''Physaria geyeri''—Geyer's twinpod *''Physaria globosa''—Globe bladderpod *''Physaria grahamii''—Graham's twinpod *''Physaria hemiphysaria''—Intermountain bladderpod *''Physaria integrifolia''—Snake River twinpod *''Physaria kingii''—King bladderpod *''Physaria lepidota''—Kane County twinpod *''Physaria lepidota''—Kane County twinpod *''Physaria navajoensis ''—Navajo twinpod *''Physaria obcordata''—Dudley Bluffs twinpod (threatened) *''Physaria occidentalis''—Western bladderpod *''Physaria okanensis''—O'Kane's bladderpod *''Physaria oregona''—Oregon twinpod *''Physaria pallida''—White bladderpod *''Physaria parviflora''—Piceance bladderpod *''Physaria parvula''—Pygmy bladderpod *''Physaria pruinosa''—Pagosa bladderpod *''Physaria reediana''—Alpine bladderpod *''Physaria repanda''—Indian Canyon twinpod *''Physaria saximontana''—Fremont County twinpod *''Physaria tenella''—Moapa bladderpod *''Physaria thamnophila''—Zapata bladderpod *''Physaria tumulosa''—Kodachrome bladderpod *''Physaria vitulifera''—Roundtip twinpod ==External links== *(Jepson Manual Treatment: ''Physaria'' ) *(USDA Plants Profile ) *(CONPS: ''Physaria'' of Colorado ) 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「Physaria」の詳細全文を読む スポンサード リンク
