一种真双子叶植物的化石，即甘肃柳属Gansufructus saligna gen. et sp. nov.，甘肃早白垩世（Aptian晚期-Albian早期）的一个新记录，该记录基于许多保存完好的轴，具有附着的叶子和果序。叶互生，具短叶柄和线状披针形，羽状到网状脉序。果序是松散的圆锥花序，在不同的成熟阶段结果实，每个包含四个部分离生的心皮，轮生排列。每个心皮有3到5个种子，沿着它的腹缘着生。叶和轴的性质表明陆生，草本的习惯。在一般组织，Gansufurts是非常相似的果轴Sinocarpus decussatus从早白垩世热河生物群，以及其他或多或少同期被子植物从远东，这一起提供了证据，不同的真双子叶植物的低身材殖民区接近沉积环境。中国西北地区早白垩世发现一种保存完好的真双子叶草本植物，为研究早期被子植物的形态、多样性和生态环境提供了重要资料。
A fossil eudicot, Gansufructus saligna gen. et sp. nov., is reported from the Early Cretaceous (late Aptian–early Albian) of the Gansu Province, Northwest China, based on numerous well-preserved axes with attached leaves and infructescences. The leaves are alternate, short petiolate and linear-lanceolate with low rank pinnate to reticulate venation. The infructescences are loose panicles bearing fruits in different stages of maturity, each containing four partly free carpels borne in a whorled arrangement. Each carpel has three to five seeds borne along its ventral margin. The nature of the leaves and axes indicates a terrestrial, herbaceous habit. In general organization, Gansufructus is closely similar to the fruit-bearing axes of Sinocarpus decussatus from the Early Cretaceous Jehol Biota, as well as other more or less contemporaneous angiosperms from the Far East, which together provide evidence of diverse eudicot angiosperms of low stature colonizing areas close to environments of deposition. An exceptionally well-preserved herbaceous eudicot was reported from the Early Cretaceous of Northwest China, providing important insights into the morphology, diversification and ecological environments of early angiosperms.
