The Upper Cretaceous sedimentary series of the Castilian marine ramp and continental basins (central northern Spain) have yielded numerous charophyte bearing sites which extend within the middle Cenomanian to upper Maastrichtian succession. The purpose of the paper is both to list the recognized charophyte taxa and to describe the sedimentary sequences in which the charophytes were found in order to reconstruct their depositional environments. The charophyte flora comprises 2 families, 15 genera and 28 species, including 3 new taxa: Lamprothamnium elongatum, Lamprothamnium ovoideum, Pseudoharrisichara sedanoensis. Among 27 charophyte bearing sites, 22 were formed during episodes of emersion and terrestrial conditions that interrupted the marine succession of the Castilian ramp, and 5 are from restricted Castilian continental basins that developed from the Campanian–Maastrichtian boundary onwards. The Campanian–Maastrichtian fossiliferous sites allow elucidating floristic and biostratigraphic correlations with the charophyte floras from Catalonia and from the Serrania de Cuenca.

卡斯蒂利亚海斜坡和大陆盆地（西班牙北部中部）的上白垩统沉积系列产生了许多轮生植物轴承位点，这些地点在中 Cenomanian 到上马斯特里赫特层序中延伸。本文的目的既是列出公认的轮生植物分类群，又是描述发现轮生植物的沉积序列，以重建它们的沉积环境。轮生植物区系包括2科15属28种，其中包括3个新分类群：Lamprothamnium elongatum、Lamprothamnium ovoideum、Pseudoharrisichara chineseoensis. 在 27 个轮生植物承载点中，22 个是在中断卡斯蒂利亚斜坡的海洋演替的浮出和陆地条件期间形成的，5 个来自从坎帕尼亚-马斯特里赫特边界向前发展的受限制的卡斯蒂利亚大陆盆地。坎帕尼亚-马斯特里赫特化石遗址允许阐明与加泰罗尼亚和昆卡塞拉尼亚轮藻植物区系的植物区系和生物地层相关性。
