摘要
1959年6月,中国科学院山西地层队,于太原西山七里沟下石盒子组底部(骆驼脖杂砂岩之顶部),曾发现一极有意义的Gigantopteris whitei Halle标本。自赫勒(1927)定此新种直到现在,有人认为此种植物的叶可能为带状,很长,不是羽状分裂,其顶部形态如何,亦不明白。而当前的标本却是羽状复叶,并有数块属于羽片顶端部分的标本。显然,这一发现使我们对该植物有了更新的认识。因此有必要对本种的特征作一些修正和补充。
The species Gigantopteris whitei was first described by Professor T.G.Halle in 1927.The specimens were collected from the province Shansi and rather fragmentary.The frond was considered probably simple and possibly forking.According to the nature of venation and the simple frond,Professor Halle thinks that this species agrees in every respect with G.americana White,Both represent a type which differs considerably from that of G.nicotianaefolia,the genotype of Gigantopteris and might be placed in another genus.This suggestion,however,is retained by Halle himself waiting for further information.
