Araceae
Also known as arum family
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe (or leaf-like bract). Also known as the arum family, members are often colloquially known as aroids. This family of 114 genera and about 3,750 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions.
AI overview
The Araceae, commonly called the arum family, are flowering plants with a distinctive flower arrangement where tiny blooms cluster on a spike-like structure called a spadix, often surrounded by a leaf-like bract called a spathe. This large family of over 3,750 species is found worldwide but is especially abundant in tropical regions of the Americas.

天南星科（学名：Araceae）是單子葉開花植物中的一科，有107屬、3700個以上的物種，主要分佈在新世界的熱帶地區，但也有些分佈於舊世界的熱帶及溫帶地區。中國有35屬約206種，主要分佈在南方各地。臺灣產16屬40種，有4種記錄為雜草[1]。由APG最近的基因研究顯示，原先獨立歸於浮萍科的植物，也應歸類於天南星科之中。 火鶴花與馬蹄蓮是本科有名的植物，常被栽培供觀賞用。粗肋草、觀音蓮、彩葉芋、黛粉葉、黃金葛、龜背芋、蔓綠絨、白鶴芋、合果芋、千年芋、美鐵芋等耐陰性強的觀葉植物可以做室內植物栽培。芋頭、蒟蒻（魔芋）地下塊莖可以加工做成蒟蒻，可以食用。半夏、天南星、千年健、犁頭尖可做藥用。水榕、隱棒花、水芭蕉、大萍等水生植物可做水族造景。巨花魔芋是全世界最高的花，其花序是植物界中最長的花序。姑婆芋（海芋屬）是一種很有名的野生植物，其植株具毒性。 目录 1 形态 2 繁衍 3 分类 3.1 内部分类 4 屬 4.1 天南星亞科 4.2 麻菖蒲亚科 4.3 棘芋亞科 4.4 浮萍亞科 4.5 龜背芋亞科 4.6 金棒芋亞科 4.7 柚葉藤亞科 4.8 美鐵芋亞科 5 参考文献 6 外部連結 形态 草本，常有辛辣味或乳状液汁，有块状或延长的地下茎，间有木质而呈攀援状，或以气根附生于他物上，少数浮生水中。 叶子多基生，如茎生则互生为2列或作螺旋状排列，全缘或分裂，常呈戟形或箭形，基部有一膜质鞘。 花极小，常有强烈臭味，排列于肉穗花序上，外围以佛焰苞，花两性全相似或单性同株，雌花在花序的下部，雄花在花序的上部，介于两者之间的常为中性花，花被在两性花中常具存，裂片4－6枚，鳞片状或合生为杯状，在单性花中缺，雄蕊一至多数，子房上位，由一至数心皮合成，每室有胚珠一至数枚。 浆果密集于肉穗花序上。 种子一至数枚埋藏在浆汁果肉中，有各种不同的外种皮。 繁衍 種子缺少胚乳，在非相似原生地，可藉由鱗莖珠芽（bulbil）行「無性生殖」，以進行繁殖。[2] 分类 天南星科属于泽泻目，在演化史上，天南星科是泽泻目已知各科中最早分化出去的一支。泽泻目各科的亲缘关系如下（节点有“*”标志的分支表示其自助法支持率介于50-70%之间，有“·”标志的少于50%，无标志者为70%以上）[3]： 澤瀉目 Alismatales * · * · · 絲粉藻科 Cymodoceaceae 流蘇菜科 Ruppiaceae 海王草科 Posidoniaceae 眼子菜科 Potamogetonaceae 大葉藻科 Zosteraceae 花香蒲科（英语：Maundiaceae） Maundiaceae 水麥冬科 Juncaginaceae 水蕹科 Aponogetonaceae 冰沼草科 Scheuchzeriaceae * · 水鱉科 Hydrocharitaceae 花藺科 Butomaceae 澤瀉科
