身边的植物 --- 棕榈科植物
   

棕榈科也叫椰子科,广泛分布于热带、亚热带地区,而以美洲和亚洲的热带地区为其分布中心其下分为刺葵亚科(仅刺葵1属,17种)、贝叶棕亚科(31属,360余种)、糖棕亚科(6属,40余种)、鱼尾葵亚科(3属,38种)、鳞果亚科(22属,600余种)、椰子亚科(22属,640种)、槟榔亚科(120属,1100种)、水椰亚科(11种,即水椰)、象牙椰亚科(315种)等九个亚科。

根据叶的分裂方式,一般以掌状叶子(扇叶类或掌叶类,大部分具掌状叶的棕榈都属于贝叶棕亚科)的叫“棕”、“榈”或“葵”;羽状叶子(羽叶类)的叫椰子。扇叶类中乔木有棕榈、蒲葵等;灌木有棕竹等。羽叶类中乔木有椰子、桄榔、鱼尾葵、槟榔、王棕、假槟榔、油棕等;灌木有山槟榔等,藤本有省藤、黄藤等;除以上陆生种类外,还有生于海边浅水中的水椰等。

 

 

           蒲葵的树干暗褐花序轴短厚不下垂,花较密集   

 

棕榈植物为常绿植物,其形态有乔木、灌木或藤本。多直立单干,不分枝;并具坚挺大叶聚生干顶。叶掌状或羽状分裂,多具长柄,叶柄基部常扩大成一纤维状鞘。花小而多,两性或单性,雌雄同株或异株,密生于叶从或叶鞘束下方的肉穗花序,常为大型佛焰苞所包被。浆果、核果或坚果,外果皮常呈纤维状。种子一粒,胚小而富胚乳,含油。

棕榈中很多种类是重要的热带经济树种。如椰子的种子制干或取油;棕枣果是著名甜品。油棕有世界油王之称。棕榈、槟榔、椰子等的树干坚韧通直且耐水湿,可作建筑用材。棕竹属植物茎干细直坚韧,可制伞柄、手杖等。有的种类还可提供优质纤维和作制糖原料。槟榔种子可入药。蒲葵叶可供制扇和编织。黄藤和省藤则是编织藤器的良好材料。除上述经济用途外,棕榈类还多应用于城市绿化观赏,由于其具有且能抗多种污染和滞尘等功能,对环境保护也有重要作用
