Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. T. Blackburn 1981 | Leaves simple with entire, serrate, or lobed margins, or pinnate;
bilateral. Stomates superficial, or in pits, or in grooves, each with pair of subsidiary cells placed parallel to pore. Cells of stomatiferous epidermis with thick or thin, pitted, straight or curved lateral walls, some with bicellular hairs. Basal cells of hairs either thick or thin walled, sometimes with beaded thickening, of even diameter throughout or expanded distally or proximally. Cylindrical hair bases present on some or all cells of the non-stomatiferous epidermis. Cuticular papillae sometimes present. |
