This study utilized scanning electron microscopy to examine the leaf trichomes of 7 species in the family Cordiaceae, including 5 species from the genus Cordia and 2 from Varronia. Various types of trichomes, including glandular, non-glandular, and stellate, were observed. Our findings highlight differences in trichome types, density, and distribution both within and between genera. This research enhances the understanding of anatomical diversity and the significance of leaf trichomes in Cordiaceae, providing a foundation for future studies in plant biology. The high diversity of trichome structure in the studied species indicates their importance for their classification. Therefore, the results of this study provide a useful insight into the diversity of trichomes and their potential as a taxonomic tool.]]></p></abstract>

Este estudio utilizó microscopía electrónica de barrido para examinar los tricomas de las hojas de 7 especies de la familia Cordiaceae; se incluyeron 5 de los géneros Cordia y 2 de Varronia. Se observaron varios tipos de tricomas, incluidos glandulares, no glandulares y estrellados. Nuestros hallazgos resaltan las diferencias en los tipos de tricomas, la densidad y la distribución tanto dentro como entre géneros. Esta investigación mejora la comprensión de la diversidad anatómica, resalta la importancia de los tricomas de las hojas en Cordiaceae y proporciona una base para futuros estudios en biología vegetal. La gran diversidad de la estructura de los tricomas en las especies estudiadas indica su importancia para su clasificación. Por lo tanto, los resultados de este estudio proporcionan una buena visión de la diversidad de tricomas y su potencial como herramienta taxonómica.]]></p></abstract>
