龍舌蘭屬（食蟲類：Agave L.）是隸屬于天門冬科的一屬，約300多種，多年生常綠被子植物門。分布于美洲，喜溫暖氣候。莖短，葉多硬質，排列成蓮座形，邊緣鋸齒狀。開花時花序從生長點伸出，花后開花的蓮座會枯萎死亡，但花序上及蓮座底部的吸芽可作為母株生命的延續。外觀類似阿福花亞科的蘆薈，但兩者的親緣關系并不相近。
形態特征
多年生植物。無莖或有極短的莖。葉呈蓮座式排列，大而肥厚，肉質或稍帶木質，邊緣常有刺或偶而無刺，頂端常有硬尖刺。花莖粗壯高大，具分枝；花通常排列成大型稠密的頂生穗狀花序或復總狀花序，有些種類每年或隔年開花一次，另一些種類只開花結果一次，開花后便死亡；花被管短，花被裂片6，狹而相似；雄蕊6，著生于花被管喉部或管內；花絲細長，常伸出于花被外，花藥丁字形著生；子房下位，3室，每室有胚珠多數，花柱線形，柱頭3裂。果長橢圓形，室背3瓣開裂；種子多數，薄而扁平，黑色。細胞染色體基數x=30。
分布范圍
原產西半球干旱和半干旱的熱帶地區，尤以墨西哥的種類最多。廣東省、福建省和云南省有逸生。

主要價值
本屬植物經濟價值較大，有些種類的纖維通稱龍舌蘭麻類，是世界著名的纖維植物之一；有些種類還含有甾體皂元，是生產甾體激素藥物的重要原料；另一些種類栽培供觀賞。葉內的纖維為硬質纖維之一，強韌耐腐，可編繩索和大纜，適為航海用。在我國引入的三種中，劍麻的品質最良，拉力大，次為龍舌蘭。
