摘要对产自西班牙西南部的十种荆芥的果实和种子进行了形态学和解剖学的研究。种子在形状、大小、种皮纹饰和内部结构上具有相当的一致性。根据蒴果的被毛可将其分为两类。第一组有分叉的毛发，而第二组没有。只有一个物种，V。童贞草可以包括在这两组中。其他性状如花冠大小或雄蕊数，支持两个类群的分离，并重申v的中间位置。virgatum。提供了区分分类群的关键。
Abstract A morphological and anatomical study of fruits and seeds of ten species ofVerbascumfrom south-west Spain has been made. The seeds showed considerable uniformity in shape, size, seed-coat ornamentation and internal structure. Two groups of species are distinguished on the basis of indumentum of the capsules. The first group has branched hairs which do not appear in the second. Only one species,V. virgatummay be included in both groups. Other characters such as corolla size or stamen number, support separation of both groups and reaffirm the intermediate position ofV. virgatum. A key to distinguish the taxa is provided.
