摘要
本文研究菰属Zizania L.及其有关属、种的外部形态后,揭示出菰属应在禾本科Gramineaee稻族Oryzeae中独立成菰亚族Zizaniinae。其与水稻属Oryza L.或拟菰属Zizaniopsis Doel&Aschers。在远古时代都可能起源于一个现已灭迹的共同祖先,而后平行向前演化。
This Paper deals with gross morphology of Zizania L. and its relatives.A total of 8 genera, 12 species, 3 varieties and 1 form were examined notonly in some collections of herbarium but also in the field of NanjingBotanical Garden Mem. Sun Yat-sen. The results, just as other characters,were suggested that genus Zizania may be considered as an isolated subt-ribe Zizaniinae in tribe Oryzeae. There are 4 species, 2 subspecies in thewhole world, i. e. Z. aquatica subsp. aqualica, Z. aqualica subsp. brevis(Fassett) S. L. Chen, Z. palustris subsp. palustris, Z. palustris subsp.interior (Fassett) S. L. Chen. Z. texana Hitchc. and Z. latifolia (Griseb.)Turcz. ex Stapf. The evolutionary trend of this genus, Zizania, may bederived from ancient stock, Which also given rise to the genus eitherOryza or Zizaniopsis, and therefore parallel evolution may have takenplace in tribe Oryzeae.
