据外媒CNET报道, 大多数花的生命都是短暂而又美丽的。而有一种特殊花朵的“美丽容颜”在缅甸琥珀中被保存了近一亿年。俄勒冈州立大学的研究人员领导的一个团队分享了这一发现,琥珀定格了这朵花绽放时的惊艳瞬间

“这不算是一朵圣诞花,但它是一种美,特别是考虑到它是一亿年前存在的森林的一部分,”琥珀专家、俄勒冈州立大学名誉教授George Poinar Jr.本周在一份声明中说。Poinar是本月在德克萨斯州植物研究所杂志上发表的一篇关于这种花的论文的主要作者。

我们看到的是一朵非常小的花的极度特写,其直径只有一英寸的一小部分。雄蕊--雄花中产生花粉的部分--以螺旋状图案保存下来。研究小组将这种花命名为Valviloculus pleristaminis,这是一个新属和新种。

“Valva是拉丁语,指的是双瓣上的叶子,loculus指的是区室化,plerus指的是很多,staminis反映了花的几十个雄性生殖器,”俄勒冈州立大学研究人员解释说。

这朵花让科学家们窥见了一段久远的植物学历史。他们怀疑这朵孤零零的雄花曾经是一种植物上的花簇的一部分,这种植物可能也有雌花。Poinar说:“尽管如此之小,但仍保留的细节令人惊叹。”
