bark
Let an agent explain bark, relay anatomy, ecology, human uses and medicinal history from botany, forestry and pharmacognosy sources, describe the named barks, advise caution with herbal products and route poisoning to poison centres, and distinguish bark from wood, cork as a specific tissue, sapwood and the dog bark sense.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain bark, relay anatomy, ecology, human uses and medicinal history from botany, forestry and pharmacognosy sources, describe the named barks, advise caution with herbal products and route poisoning to poison centres, and distinguish bark from wood, cork as a specific tissue, sapwood and the dog bark sense.
The outer layers of woody stems and roots outside the vascular cambium, including inner living bark or phloem that transports sugars and outer dead cork that protects against water loss, fire, pests and pathogens, with forms and uses the registry aliases name including birch bark used for canoes, containers and writing, ash bark, oak bark or Quercus cortex used in tanning and traditional remedies, barberry and caper bark in herbal traditions, and bark chips used as garden mulch; medicinal barks such as cinchona gave quinine and willow bark led to aspirin. Stripping bark around a tree, called girdling, kills it, and some herbal bark products can interact with medicines.
What it is for: Protecting trees and supplying materials and medicines.
It can be explain anatomy and ecology; relay human uses; describe named barks; relay herbal safety.
Distinguishing features
Protective layer
Living inner phloem
Species-specific texture
Useful materials and medicines
What it looks like
Rough, smooth, peeling or fissured outer covering of trunks and branches.
Physical character
inner bark: secondary phloem note
cork oak harvest cycle: about 9 years
quinine isolated from cinchona bark: 1820 year - Pelletier and Caventou
How it is recognised
Outer tissues of woody stems
Barberry bark, ash bark, caper bark, Quercus cortex, birch bark, bark chips
Wood is inside the cambium; cork is a bark layer; sapwood is outer wood; a dog s bark is a sound
