certain
- von Mohl's classification : Mauritia-Type
- shape of fibrous part in transverse section : Sagittata ; Reniforma to Cordata - Complanata
- cortex : very thin
- superficial protective layer (sub-epidermal) : developed etagen meristem (alignment of more than 10 cells) ; suberization and sclerosis of the existing ground parenchyma
- tangential elongation and anticlinal divisions of subcortical parenchyma cells : present ; absent
- fibrous bundles in central cylinder : present ; absent
- fibrous ventral cap : absent
- little fibrous vascular bundles (bridges) : absent (poorly developed)
- number of phloem strand : one strand throughout the central cylinder
- radial elongation of the fibrous dorsal cap (in subcortical zone) : strongly developed ; absent
- radiating parenchyma : absent
- ground parenchyma of the central cylinder : cells slightly elongated (length / width < 3–4), lobed with a random (rhombohedral) shape (maximal length < 200 µm) and irregular meshwork (lacunae < 200 µm) ; trabecular (= stellate) with a regular meshwork (spheroid lacunae > 250 µm)
- ground parenchyma sustained growth : present (Type B)
- phytoliths : globular echinate to granulate
- number of wide metaxylem element per fibrous vascular bundle : mostly 1 ; 1 in the the subcortical zone and the zone of transition AND 2 in the central zone
- tabular parenchyma : absent
- end wall slope : oblique ; slightly oblique
- specialisation value : 5 vessel-parenchyma pits, or with ≤ 3 bars">[4] multiple perforation plates with "wide" perforations that span >5 vessel-parenchyma pits, or with ≤ 3 bars ; [5] mixture of multiples perforation plates (as in #4) and simple perforation plates ; [6] simple perforation plate only
- wide metaxylem element : present
- fibrous dorsal cap centrifugal differentiation : present
- metaphloem sieve plate : simple or transitional
- phytoliths distribution in central cylinder : largely restricted to the fvb of the subcortical zone in contact with the cortex
