根状茎横卧，粗大，肉质，密被蓬松的长鳞片，有被毛茸的线状根混生于鳞片间，弯曲的根状茎盘结成为大块的垫状物，由此生出一丛无柄而略开展的叶，形成一个圆而中空的高冠，形体极似巢蕨Neottopteris nidus (L.) J. Sm.；鳞片钻状长线形，深锈色，边缘有睫毛。叶一型，长圆状倒披针形，长80-120厘米或过之，中部宽20-30厘米，顶端渐尖，向下渐变狭，至下约1/4处狭缩成宽1-2厘米的翅，至基部又渐扩张成膨大的圆心脏形，宽约15-25厘米，有宽缺刻或浅裂的边缘，基部以上叶片为羽状深裂，再向上几乎深裂到叶轴；裂片多数，斜展或略斜向上，被圆形的缺刻所分开，披针形，中部的裂片长达15-22厘米，宽2-3厘米，急尖头或圆头，为阔圆形的缺刻所分开；叶脉粗而很明显，侧脉斜展，隆起，通直，相距4-5毫米，向外达于加厚的边缘，横脉与侧脉直角相交，成一回网眼，再分割一次成3个长方形的小网眼，内有顶端成棒状的分叉小脉；叶硬革质，两面均无毛，干后硬而有光泽，裂片往往从关节处脱落。孢子囊群位于小脉交叉处，叶片下半部通常不育，4-6个生于侧脉之间，但并不位于正中央，而是略偏近下脉，每一网眼内有1个孢子囊群，在主脉与叶缘间排成一长行，圆球形或长圆形，分离，但成熟后常多少汇合成一连贯的囊群线。
