Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. E. Artabe et al. 2004 | Cataphyll and leaf bases in alternating cycles. Polyxylic stem covered bycataphylls and persistent rhomboidal foliar bases. Vascular cylinder with six rings of collateral vascular bundles with phloem toward the outside and divided into fanlike sectors by multiseriate, parenchymatous rays. Foliar traces run irregularly, and as they pass through wide rays to theouter cortex they curve, producing a girdling configuration. |
