Studies of leaf surface of some Bursera Jacq. ex L. (Burseraceae) species and its taxonomic implications
Leaf epidermis characteristics of six species of Bursera were studied using light and scanning electron microscopy (SEM). All species possess hypostomatic leaves, anomocytic stomata, and similar glandular and eglandular trichomes, with the exception of B. karsteniana which is glabrous. SEM of the le...

| description | Leaf epidermis characteristics of six species of Bursera were studied using light and scanning electron microscopy (SEM). All species possess hypostomatic leaves, anomocytic stomata, and similar glandular and eglandular trichomes, with the exception of B. karsteniana which is glabrous. SEM of the leaf epidermis revealed that all have straight anticlinal walls, but these have a suite of sculptural characters unique to each species. Phenetic analyses separate the species into two groups, one formed by the three representatives of subgenus Bursera and the other by the three representatives of subgenus Elaphrium, supporting the aforementioned subdivision. Leaf epidermis features are taxonomically important for the genus. |

All species possess hypostomatic leaves, anomocytic stomata, and similar glandular and eglandular trichomes, with the exception of B. karsteniana which is glabrous. SEM of the leaf epidermis revealed that all have straight anticlinal walls, but these have a suite of sculptural characters unique to each species.

Leaf epidermis features are taxonomically important for the genus. Se realizó el estudio de las características de la epidermis foliar de seis especies de Bursera. Las muestras fueron analizadas utilizando técnicas de microscopía óptica y electrónica de barrido (MEB). Todas presentaron hojas hipostomáticas, estomas anomocíticos y el mismo tipo de tricomas glandulares y tectores, con excepción de B. karsteniana que es glabra. La micromorfología de la epidermis foliar vista al MEB mostró que todas tienen paredes anticlinales rectas, sin embargo éstas presentan una combinación única de caracteres para cada especie. Los análisis fenéticos separan dos grupos, uno formado por los tres representantes del subgénero Bursera y otro por los tres pertenecientes al subgénero Elaphrium, lo cual apoya la mencionada subdivisión. Los caracteres de la epidermis foliar mostraron un alto valor taxonómico en Bursera.
