1. Review existing anatomy/morphology terms and definitions

Cell types related to wood

tracheary elements

  • tracheary element (PO:0000290)
  • tracheid (PO:0000301) need to make it clearer that a perforation is a specific anatomical entity, not just some random hole.

initial cells (PO:0004011)

  • cambial initial
  • fusiform initial (PO:0000079) (syn.: xylem initial, xylem mother cell) Need to work on this term. May be better as synonym of cambial initial. Xylem mother cell should not be a synonym, but should be a separate term.

  • ray system (PO:0025411)

2. Develop list of anatomy/morphology terms that are missing

Do we need only wood-related terms, or other terms for woody plants? Will also need terms for some structures found in gymnosperms, such as reproductive structures.

See new page for Wood Ontology PO and GO Term Development.

wood related term suggestions

Terms for PO:

reaction wood/tension wood/compression wood - review by Wilson and Archer

aggregate ray (also maybe homogenous, heterogenous, uniseriate, multiseriate, fusiform rays)

storied cambium and ray

non-storied cambium and ray

aggregate ray, homogenous or heterogeneous, uniseriate, multiseriate

oil cell

ray tracheid

traumatic resin

(apotracheal, paratracheal, marginal, aliform, confluent) axial parenchyma

read review of laticifer cells by Pickering

knot loose and tight

interfascicular cambium

vascular bundle types - amphicentric, vasicentric, medulary

inter- and intra-xylary phloem

successive cambium

epithelium cell

ray tracheid and subtypes

cambial zone

square cell

axial parenchyma strands

resin canal

pith flecks (maybe)

breakdown ray area

cambial zone

xylem mother cell, and work on definition of phloem mother cell and cambial initial

inner and outer bark

terms for how vessels and parenchyma are arranged in wood (e.g., vascicentric)

Terms for GO:

pit, pit types, torus, margo, simple, membrane types, tyloses etc.,

casparian strip

mineral inclusions: calcium oxalate, silica, druses


See good description in Eames, also see Esau.


plant secondary cell wall pit: A cavity in a plant secondary cell wall with an pit membrane, open internally to the lumen.

primary cell wall pit: An area of a primary plant cell wall is thin.

The primary wall of the adjacent cell is also thin in the same place.


Except blind pit, which is only on one side.


pit membrane

simple pit

bordered pit

primary pit field


perforation: the opening between two vessel elements

intrusive growth

cambial dormancy (or just add stage)

other suggestions

Add term xylem cell and phloem cell -- XP of cell and part_of xylem of phloem. Can't create terms for secondary xylem or secondary phloem cells, because most of the cell types can appear in both primary and secondary vascular tissue.

Xylem cell should be linked to the definition of pulp and paper (useful for TO)

Terms for gum/latex/resin? Too broadly defined. Could look up specific definitions in ethnobotanical literature, but people may not use them consistently.
