灰叶剑麻龙舌兰科（Agavaceae） 龙舌兰属多年生草本。叶纤维作物。从叶子获得的纤维又称墨西哥马盖、汉尼昆。原产墨西哥尤卡坦半岛， 现中美洲古巴、 哥斯达黎加、危地马拉、洪都拉斯等国家都有分布。主产国为墨西哥。20世纪50年代引入中国海南省，现海南、广东、广西和福建等地有少量种植。叶片疏生，狭长，肉质，长 100～180厘米，宽8～14厘米，灰绿色,叶面多蜡粉,边缘有刺；圆锥花序，轴高5～7米,花灰绿色,花蕾较短,长约5厘米,花梗短,萼筒与裂片等长，花气味不良。体细胞染色体数为140(基数30)，属非整倍的五倍体,杂交后代不育。植株耐寒力较强，并耐旱、耐瘠，能在荒漠地区生长，适宜生长于年平均气温26℃(上限40℃,下限10.5℃)、年降水量750～1250毫米的环境；在珊瑚岩风化石灰性红壤、火山灰和滨海沙壤上生长良好。抗病虫能力也强。栽培技术与剑麻基本相同。用珠芽或吸芽作繁殖材料。田间管理较粗放。定植后5～6年开始割叶,约6个月收割1次。单株年长叶20～30片，纤维率4％左右。生命周期15～30年，产叶270～330片。纤维洁白，有光泽，束纤维长120～150厘米，拉力强度为50～60千克，主要用于制绳索、地毡、麻布、麻袋等。叶汁含海柯吉宁等多种皂苷元，可制药。育种上可用作杂交亲本。
