澳大利亚轮藻植物研究历史悠久 ,迄今约有 95种被描记。在 Wood(1972 )对澳大利亚轮藻植物的修订研究中 ,一些种因为标本遗失或已损坏而未包括在内 ,其中有的种近年来又被重新发现。本文重点介绍 N itella hookeriA.Br.var.arthroglochin A.Br.,Lychnothamnus barbatus(Meyen) L eonh.和 N itella partita Nordst.的发现过程及其产地生态环境 ,探讨了季节性湿地对轮藻植物的保护意义。 N.hookeri var.arthroglochin早在 185 4年就发现于澳大利亚 ,并于 1887年再次作为澳大利亚特有物种而被记录 ,然而从此销声匿迹 ,直至 1989年才再度问世 ,它重新出现的地点为新南威尔士州高海拔花岗岩风化土壤地区的季节性溪流中。L.barbatus则为 R.D.Wood首次发现于 196 0年 ,嗣后一再搜寻并无踪迹 ,直到 1996年才于昆士兰东南地区亚热带阵发性溪流中被再次发现。昆士兰中部干旱地区 1889年一度见到的 N.partita,也是近一百年后才在新南威尔士州西北干旱地区的季节性湿地再次发现。
There are about 95 species described so far in Australia. In Wood’s (1972) revised study of Australian charophytes, some species were not included because of missing or damaged specimens, some of which were rediscovered in recent years. This article focuses on the discovery process of Nietella hookeriA.Br.var.arthroglochin A.Br., Lychnothamnus barbatus (Meyen) L eonh. And Nietella partita Nordst. And the ecological environment of its origin. The effects of seasonal wetlands on the Protect meaning. N.hookeri var .arthroglochin was found in Australia as early as 1984, and was once again recorded as an endemic species of Australia in 1887. However, it disappeared from the world until 1989 and reappeared in New South Wales Seasonal streams in high altitude granite weathered soils. L. barbatus was R.D.Wood first discovered in 1960 and subsequently searched repeatedly without trace until it was discovered again in subtropical paroxysmal streams in southeastern Queensland in 1996. N.partita, once seen in arid areas of central Queensland in 1889, was rediscovered once again in seasonal wetlands in arid northwestern New South Wales nearly a hundred years ago.
