楔叶类(化石)xieye lei(huashi)楔叶类(化石)Sphenopsida(fossil) 楔叶类是很古老的原始维管植物,构成一个纲或门,又称节蕨植物、有节植物。最早出现于早泥盆世,到石炭二叠纪最为繁盛。乔木类型的芦木与石松类的鳞木和封印木共同繁殖在北半球热带的沼泽地区形成森林。到中生代本类植物逐渐衰退,木本类型几乎绝迹。侏罗纪(距今1.36~1.9亿年)以后只有木贼一属,与现代的相同。曾被作为蕨类植物门的一个纲,但近来有人主张将其独立为一个门。 楔叶类具有根、茎和叶。茎有明显的节和节间。枝、叶都轮生。孢子囊着生于相当于孢子叶的孢囊梗上。孢囊梗聚集于茎尖,组成一个孢子叶球。孢子同形或很不显著的异形。 最原始的类型是叉叶目。叉叶目中的早泥盆世的原始叉叶是小形草本植物。节与节间分化不明显。孢子囊生于孢子囊梗的尖端。到早泥盆晚期和中泥盆世(距今约3.7亿年左右)出现叉叶。 也是小形草本植物。它们的节与节间分化亦不明显,但孢子叶梗向下弯曲。到中泥盆世晚期出现芦叶,也是小形草本植物,它们的茎分化成短节间与节。 以后,叉叶目进一步向3个方面发展:羽叉叶目和楔叶目为两个进化旁支;基干则进化为木贼目。 楔叶类可作为蕨类植物门的一个纲,一般可分为4目: ①叉叶目 叶通常反复二歧分叉,分裂成线状裂片。孢子叶集生于枝条前端,形成相当于一种极疏松的孢子叶球。出现于早、中泥盆世。 ②羽叉叶目 叶反复二歧分叉为若干小叶。小叶羽状全裂。孢子叶球长而疏松,由轮生的相似于退化的营养叶的孢子叶组成。孢子囊着生于孢子叶的下面。出现于晚泥盆世。 ③楔叶目 叶无柄,楔形。孢子叶球由紧密的孢子叶组成,孢子叶分化为载孢囊的孢囊梗和不孕的苞片出现于晚泥盆世至晚二叠世。 ④木贼目 叶小形,轮生,常为鳞片状,有的基部连成鞘。孢子叶球由轮状紧密排列的盾状孢子叶组成。出现于早石炭世至现代。 石炭二叠纪的瓢叶目、盘穗目和齿叶目有人认为可列入楔叶纲中。                 徐仁
