''Dermatophyllum'' is a genus of three or four species of shrubs and small trees in the subfamily Faboideae of the pea family, Fabaceae. The genus is native to southwestern North America from western Texas to New Mexico and Arizona in the United States, and south through Chihuahua, Coahuila and Nuevo León in northern Mexico. Members of the genus are commonly known as mescalbean, mescal bean or frijolito. One of the common names of ''Dermatophyllum secundiflorum'' is Texas mountain laurel, although the name mountain laurel also refers to the very dissimilar and unrelated genus ''Kalmia'' (family Ericaceae) and the name laurel refers generally to plants in the unrelated order Laurales. Although still commonly treated in the genus ''Sophora'', recent genetic evidence has shown that the mescalbeans are only distantly related to the other species of ''Sophora''. ==Species== ''Dermatophyllum'' comprises the following species:〔 * ''Dermatophyllum arizonicum'' (S.Watson) Vincent—Arizona Mescalbean (Arizona, Chihuahua) * * subsp. ''arizonicum'' (S.Watson) Vincent * * subsp. ''formosum'' (Kearney & Peebles) Vincent (Arizona) * ''Dermatophyllum gypsophilum'' (B.L. Turner & A.M. Powell) Vincent—Guadalupe Mescalbean (Southern New Mexico, western Texas, Coahuila) * ''Dermatophyllum guadalupense'' (B.L. Turner & A.M. Powell) B.L.Turner * ''Dermatophyllum juanhintonianum'' (B.L. Turner) B.L. Turner * ''Dermatophyllum secundiflorum'' (Ortega) Gandhi & Reveal—Texas Mescalbean (Texas, New Mexico, Coahuila, Nuevo León) * ''Dermatophyllum purpusii'' (Brandegee) Vincent 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「Dermatophyllum」の詳細全文を読む スポンサード リンク
