RESUMEN. Micromorfología y anatomía de dos especies Mediterráneas del género Ajuga L. (Lamiaceae). Se ha estudiado la morfología y la anatomía de tres taxones mediterráneos del género Ajuga L.: A. chamaepitys (L.) Schreb., A. iva (L.) Schreb. var. iva y A. iva var. pseudo-iva (DC.) Benth. A. iva s. I. muestra nticulas de reticuladas a alveoladas, y A. chamaepitys, de ligeramente crestadas a reticuladas transversalmente. La presencia de células esclerenquimáticas más o menos isodiametricas y de tamaño variable formando una capa gruesa en el mesocarpo relacionan filogenéticamente este género con Verbenaceae. Así mismo, con los caracteres de las núculas, se propone una clave para diferenciar los citados taxones.
Palabras clave. Núcula, pericarpo, morfología, anatomía, Ajuga, Ajugoideae.
ABSTRACT. Micromorphology and anatomy of two Mediterranean species of Ajuga (Lamiaceae). A morphological and anatomical study of three Mediterranean taxa of Ajuga L. has been made; A. chamaepitys (L.) Schreb., A. iva (L.) Schreb. var iva and A. iva var pseudo-iva (DC.) Benth. A. iva s. I. has reticulate to alveolate nutlets, and A. chamaepitys has slightly crestate to transversaly reticulate nutlets. The presence of a thick isodiametric sclerenchymatic cell layer in the mesocarp show the phylogenetic relationship between this genus and Verbenaceae family. Also, a key to differentiate the three taxa is provided.
Key words. Nutlet, pericarp, morphology, anatomy, Ajuga, Ajugoideae.
