This plant is native to California, Baja California, Arizona, Oregon, and Utah. 〔(USDA: ''Cheilanthes covillei'' )〕 It grows in rocky crevices in the mountains and foothills. In California it is found in Chaparral, Yellow pine forest, Pinyon-juniper woodland, and Joshua tree woodland habitats. 〔 ==Description== This fern has green leaves which may be up to 4-pinnate, that is, made up of leaflets that subdivide 3 times, such that the leaflets are layered with overlapping rounded segments. The leaves have a bumpy, cobbled look. The undersides of the leaves have scales which are lengthened outgrowths of the epidermis. Tucked under the scales are the sporangia, which make the spores. 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「Cheilanthes covillei」の詳細全文を読む スポンサード リンク
