''Zamia integrifolia'' is a small, tough, woody cycad native to the southeast United States (Florida, Georgia), the Bahamas, Cuba, Grand Cayman and possibly extinct in Puerto Rico and Haiti. ''Zamia integrifolia'' produces reddish seed cones with a distinct acuminate tip. The leaves are 20–100 cm long, with 5-30 pairs of leaflets (pinnae). Each leaflet is linear to lanceolate or oblong-obovate, 8–25 cm long and 0.5–2 cm broad, entire or with indistinct teeth at the tip. They are often revolute, with prickly petioles. It is similar in many respects to the closely related ''Zamia pumila'', but that species differs in the more obvious toothing on the leaflets.〔(Linnaeus, Carl von f. 1789. Hortus Kewensis 3: 478 )〕 This is a low-growing plant, with a trunk that grows to 3–25 cm high, but is often subterranean. Over time, it forms a multi-branched cluster, with a large, tuberous root system, which is actually an extension of the above-ground stems. The leaves can be completely lost during cold periods, with the plant lying dormant in its tuberous root system, allowing this cycad to be relatively cold hardy. The plant can survive up to USDA region 8b (this can be quite northern: for instance, Seattle is 8b). The stems and leaves will regenerate after the cold period subsides with full foliage 〔〔Whitelock, L. M. (2002). ''The Cycads''. Portland, OR: Timber Press.〕 Like other cycads, ''Zamia integrifolia'' is dioecious, having male or female plants. The male cones are cylindrical, growing to 5–16 cm long; they are often clustered. The female cones are elongate-ovoid and grow to 5–19 cm long and 4–6 cm in diameter.〔 ==Common names== This plant has several common names. Two names, Florida arrowroot and wild sago, refer to the former commercial use of this species as the source of an edible starch. Coontie (or koonti) is derived from the Seminole Native American language ''conti hateka''. 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「Zamia integrifolia」の詳細全文を読む スポンサード リンク
