Abstract

Foliar anatomical characters of Polygonum minus Huds. were described to determine their taxonomic significance and implications. Comprehensive micromorphological study on leaf epidermis was investigated on both adaxial and abaxial surfaces by light and scanning electron microscopy. The epidermal cells on adaxial surface are polygonal, while irregularly shaped cells were observed on the abaxial surfaces. Stomata show paracytic pattern. Reticulate venation and one layer of palisade cells with elongate-prismatic in shape were observed, as well as druse and perismatic crystals recorded. Epidermal cavities were observed in both adaxial and abaxial sides. Two trichome types were identified: peltate secretory and non-secretory trichomes (conical brushlike clustered, simple multicellular and multiseriate). We report the presence of peltate glandular secretory trichomes in P. minus. These findings suggest an adjustment of the taxonomic description of the genus Polygonum section Persicaria.
