| 摘 要： | 该文报道了发现于浙江省景宁畲族自治县山地沼泽中的莎草科水葱属一中国新记录种———穗芽水葱(Schoenoplectus gemmifer C. Sato, T. Maeda ＆ Uchino)。该种外形与水毛花相似,但其秆质地较柔软,小穗较短,花柱2,具无性繁殖的穗芽。染色体数目为2n ＝78±2(水毛花的染色体数目为2n ＝44)。文献记载穗芽水葱特产于日本,并被列为日本稀有物种。该种在景宁的发现,对研究中国—日本植物区系具有重要学术价值。

| Abstract: | Schoenoplectus gemmifer C. Sato, T. Maeda & Uchino was found to occur in Jingning She Autonomous County in Zhejiang Province, China. This represents a new record of this species from China. The species is similar to Schoenoplectus mucronatus, but differs from the latter in its caulis soft texture, shorter spikelets, style 2, asexual reproduction buds on caulis, and its chromosome number was 2n = 78 ± 2(while 2n = 44 for S. mucronatus). It has great academic value to research the relationship between China and Japan as a special and rare species in Japan. |
