''Caulanthus crassicaulis'' is a species of flowering plant in the mustard family known by the common name thickstem wild cabbage. It is native to the western United States where it is a member of the flora in sagebrush, woodland, and desert scrub habitats. This is a perennial herb producing a stout, inflated stem from a woody caudex base. The leaves form a basal rosette and occur at intervals along the stem. They are broadly lance-shaped on the lower stem and much smaller and linear in shape farther up. They may have smooth, toothed, or deeply cut edges. The rounded flower has a coat of thick, pouched sepals which part at the flower tip to reveal narrow dark purple or brown petals. There are two varieties of this species: var. ''crassicaulis'' generally has hairy flowers, while var. ''glaber'' has hairless. The fruit is a long, thin silique which may approach 13 centimeters in length. ==External links== *(Jepson Manual Treatment ) *(USDA Plants Profile ) *(CalPhotos photo gallery ) *(NatureServe Explorer ) 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「Caulanthus crassicaulis」の詳細全文を読む スポンサード リンク
