| Reference | Diagnosis | |
|---|---|---|
| T. C. Lantz et al. 1999 | Stem upright, enclosed by two layered sclerotic hypodermis, covered by persistent petiole bases, adventitious roots, and dense indument of multicellular, uniseriate trichomes. Cauline vasculature an amphiphloic dictyostele, meristeles producing three parted leaf traces in stem and stipe; accessory bundles absent. Leaf gap obovate with one constriction, length/width ratio 2.5: 1. Stem and leaf trace vascular tissues surrounded by sclerenchyma. Leaf
trace protoxylem associated with protoxylem cavities and cavity parenchyma. Cubical cells absent from ground tissue. Diarch adventitious roots diverge from cauline meristeles near leaf gap margins. |
