On the true identity of Mendoncia “stellate” trichomes
ABSTRACT The present survey of leaf-blade trichomes of Mendoncia used SEM and light microscopy to investigate the diversity of trichome types in Neotropical and Paleotropical species of the genus. The eglandular trichomes are filiform, uniseriate, with asymmetric epidermal cells arranged radially ar...

| description | ABSTRACT The present survey of leaf-blade trichomes of Mendoncia used SEM and light microscopy to investigate the diversity of trichome types in Neotropical and Paleotropical species of the genus. The eglandular trichomes are filiform, uniseriate, with asymmetric epidermal cells arranged radially around the trichome, these epidermal cells may be short or elongated, oriented in two groups. These cells, when elongated, are covered with epicuticular wax, forming smooth thick plates. African species have dendritic but not stellate trichomes. Character states such as number and length of basal cells were shown to overlap within the same species and therefore their use in isolation is not recommended for subgeneric classification of Mendoncia. Neotropical Mendoncia trichomes with well-developed epidermal cells arranged radially around the trichome appear to be unique to this group, without parallel in other plant families. |
