太原西山煤田太原组煤核中的科达植物雄性繁殖器官

本文描述了山西太原西山煤田太原组7号煤层煤核中的3种石化科达植物雄性繁殖器官的解剖构造特征。Cordaianthus ramcnt-rarus sp. nov. 具螺旋状排列的苞片及生殖短枝,生殖短枝呈扁状,不育鳞片数目很少。C. ximinensis sp. nov. 的苞片及生殖短枝呈四列状着生于主轴上,主轴横切面呈菱形或四边形。C. cf. concinnus Delevoryas与欧美植物区的C. concinnus Delevoryas的区别在于其鳞片排列较紧密。欧美植物区的Cordaianthus的苞片及生殖短枝几乎都是呈二列状着生于主轴上。本文报道的C. rament-rarus sp. nov. 的苞片及生殖短枝在主轴上则以螺旋状排列,代表一种新的类型,其进化程度可能比二列状排列的类型要高。

中国姜黄属植物的订正

将白顶姜黄（CurcumaalbicomaS．Q．Tong）归入川郁金（C．sichuanenslsX．X．Chen),将另一种“川郁金”（C．chuanyujinC．K．HsiehetH．Zhang）归入广西莪术（C．kwangsiensisS．G．LeeetC．F．Liang）。认为过去把莪术鉴定为C．zedoaria（Christ．）Rose．C．caesiaRoxb．或C．aeruginosaRoxb,其实都是C．phaeocaulisVal．的误定;C．elataRoxb．是C．wenyujinY．H．ChenetC．Ling的误定;认为广西莪术的两个变种,即紫脉莪术（C．kwangsiensisvar．affinisY．H．Chen）和毛莪术（C．kwangsiensisvar．puberulaY．H．Chen）不能成立．对台湾是否产C．viridifloraRoxb．表示怀疑。附有中国产姜黄属植物12种的检索表及其分布．
