Coriaria ruscifolia的雌蕊群由5个心皮组成，心皮的下部相连。它被解释为合生心皮，而不是离生心皮，并被认为代表五个盾形心皮，在一个非常短的腹裂上方游离，并在裂下方沿沿着它们的中间部分狭窄地连接，如通过如此多的纵向条带。每个心皮的游离部分由单面花柱（没有腹裂）及其与心皮腹裂水平上的联合部分的短连接组成。接合部分是心皮的海鞘区域，其基部结合是实心的。通过对叶状雌蕊的研究，我们发现了马桑属心皮与叶的同源性，并对英语植物学家所误解的“盾形”概念作出了更清楚的解释。
Summary The gynoecium of Coriaria ruscifolia is made up of five carpels joined in their lower parts. It is interpreted as syncarpous, not apocarpous, and is considered to represent five peltate carpels free above a very short ventral split and joined narrowly below the split along their median parts, as by so many longitudinal strips. The free part of each carpel consists of the unifacial style (without ventral split) and its short junction with the associate part of the carpel at the level of the ventral split. The joined parts are the ascidiate regions of the carpels with their solid basal union. The study of phyllodic gynoecia enables us to discover the homologies between carpel and leaf in Coriaria and to explain more clearly the peltation concept, which appears to have been misunderstood by English-speaking botanists.
