本期特刊重点介绍了澳大利亚本土烟草的一些奇妙品种（烟叶节。Suaveolentes）。我们在这里介绍这个属的十二种，其中四种是科学上新发现的。许多烟叶属植物具有很高的观赏价值，我们希望，尤其是澳大利亚的稀有物种，能找到一种方法进入园艺，以防止它们受到威胁。这将允许维持迁地种群，减轻气候变化和引进入侵物种的影响。烟草大约在200万年前散布到澳大利亚内陆，现在正在向那里辐射。很明显，它们具有有趣的细胞学进化和形态差异。它们似乎具有特殊的干旱适应能力，这是生长在地球上一些最干旱地区的薄叶草本植物所需要的。
This special issue highlights some of the wonderful species of native Australian tobacco (Nicotiana sect. Suaveolentes). We here present twelve species of this genus, four of which are new to science. Many Nicotiana species have a high ornamental value, and we hope that particularly the rarer Australian species will find a way into horticulture to prevent them from becoming threatened. This would allow maintenance of ex-situ populations, mitigating the effects of changing climate and introduction of invasive species. Tobaccos dispersed into the Australian outback around two million years ago and are now radiating there. It has been clear that they have interesting cytological evolution as well as morphological differences. They appear to have peculiar drought adaptations, which are needed for thin-leaved herbs growing in some of the driest places on the planet.
