本文综述了禾本科植物叶化石的研究进展，并讨论了它们在解释进化、过去和现在的分布和环境方面的有用标本。没有明确的白垩纪产状。然而，有证据表明，现存的谱系可以追溯到古新世以后，包括Persoonioideae亚科的Persoonieae部落和Grevilleoideae亚科的四个部落中的每一个。澳大利亚化石记录具有高度多样性和丰富性的特点，包括硬叶和旱生形式，但几乎没有证据表明突出的现存亚科变形藻亚科。新西兰拥有比现在高得多的Proteaceae多样性，包括稀疏-中新世的开阔植被物种。南美的叶子化石记录并不广泛。然而，化石记录与它们现存的近亲在南美洲和澳大利亚的分布是一致的，这是进化的结果。总体而言，有必要进行更多的研究，将Proteaceae的叶子化石置于系统发育的背景下。
Foliar fossils of Proteaceae are reviewed, and useful specimens for interpreting evolution, and past and present distributions and environments are discussed. There are no definite Cretaceous occurrences. However, there is evidence of extant lineages dating from the Paleocene onwards, including tribe Persoonieae of subfamily Persoonioideae and each of the four tribes of subfamily Grevilleoideae. High diversity and abundance characterizes the Australian fossil record, including sclerophyllous and xeromorphic forms, but there is little evidence of the prominent extant subfamily Proteoideae. New Zealand had a much higher diversity of Proteaceae than at present, including Oligo-Miocene species of open vegetation. The South American leaf fossil record is not extensive. However, the fossil records of Embothrieae and Orites are consistent with the distributions of their extant relatives in South America and Australia being the result of vicariance. Overall, there is a need for more research on placing Proteaceae leaf fossils in a phylogenetic context.
