- Diagnosis
- Diameter of stem small: 10±11 mm. Primary xylem architecture eustelic. Foliar bundles extend through 5 internodes before entering the rachis bases; foliar bundles do not divide along their trajectory through the stem. Longitudinally oriented sclerenchyma strand accompanies the diverging foliar vascular bundle adaxially in the cortex and is incorporated in
the outer cortex above the level of divergence of the foliar rachis. Capitate glands absent.
