''Fouquieria'' is a genus of 11 species of desert plants, the sole genus in the family Fouquieriaceae. The genus includes the ocotillo (''F. splendens'') and the boojum tree or cirio (''F. columnaris''). They have semisucculent stems with thinner spikes projecting from them, with leaves on the bases spikes. They are unrelated to cacti and do not look much like them; their stems are proportionately thinner than cactus stems and their leaves are larger. These plants are native to northern Mexico and the bordering US states of Arizona, southern California, New Mexico, and parts of southwestern Texas, favoring low, arid hillsides. The Seri people identify three species of ''Fouquieria'' in their area of Mexico: ''jomjéeziz'' or ''xomjéeziz'' (''F. splendens''), ''jomjéeziz caacöl'' (''F. diguetii'', Baja California tree ocotillo), and ''cototaj'' (''F. columnaris'', boojum). The genus is named after French physician Pierre Fouquier (1776-1850). The spines of ''Fouquieria'' develop in an unusual way, from a woody thickening on the outer (lower) side of the leaf petiole, which remains after the leaf blade and most of the petiole separate and fall from the plant.〔W. J. Robinson, 1904. The spines of ''Fouquieria''. ''Bulletin of the Torrey Botanical Club''. 31(1):45–50〕 == Classification == ''Fouquieria'' species do not have a particularly close resemblance to any other sort of plants; genetic evidence has shown they belong in the Ericales. Prior to this, they had been variously placed in the Violales or their own order, Fouquieriales. 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「Fouquieria」の詳細全文を読む スポンサード リンク
