- Sparsely branched, isophyllous, actinostelic axes with 6–20
exarch protoxylem groups separated by deep dissections; metaxylem
tracheids variably polygonal, bearing close-spiral or scalariform thickenings.
Narrow zone of phloem bounded by endodermis. Narrow
inner cortex of thin-walled parenchyma;weakly developed middle cortex;
thin outer cortex of thick-walled cells; uniseriate, un-ornamented
epidermis. Univeined leaves ovate, elliptical, or rhombic, helically
arranged, sessile; margins microcrenulate; apex acute. Roots sparsely
dichotomous, circular to transversely elliptical, monarch with eccentrically
positioned vascular strand. Extra-vascular tissues of roots
consisting of thin-walled inner cortex cells, thick-walled outer cortex
cells and uniseriate epidermis.
