Purpose and description
Enable an agent to identify Pistacia lentiscus, assess the condition and reproductive state of its plants, and choose site-appropriate cultivation, conservation or resin-harvest actions.
Pistacia lentiscus L., commonly called the mastic tree or lentisk, is an evergreen, dioecious shrub or small tree in the Anacardiaceae, native to the Mediterranean region, with pinnate leaves, small drupes and aromatic resin.
It can be Document diagnostic organs and route ambiguous plants for botanical verification.; Assess planting-site suitability using local exposure, drainage and establishment evidence.; Track flowering sex, fruit development and recruitment to investigate reproductive success.; Select and document seed or cutting propagation with traceable parent material.; Plan and evaluate pruning, irrigation or protection using observed plant responses.; Evaluate whether a documented resin-harvest protocol is appropriate for a particular plant and monitor recovery..
Distinguishing features
Check complete mature leaves for paired leaflets without a terminal leaflet and a winged central leaf axis; use this combination when resolving identification among Pistacia candidates. [Botanical description](https://www.treesandshrubsonline.org/articles/pistacia/pistacia-lentiscus/)
Confirm persistent, leathery, aromatic compound foliage across seasons; leaf retention and architecture together are more useful than a common name such as mastic. [RHS profile](https://www.rhs.org.uk/plants/25153/pistacia-lentiscus/details)
Inspect reproductive structures: male and female flowers occur on separate plants, and pollinated female flowers develop small fruits that change from reddish to black; these support identification but are not independently diagnostic. [RHS profile](https://www.rhs.org.uk/plants/25153/pistacia-lentiscus/details)
Distinguish the woody plant from a resin sample or product labelled mastic: identification requires botanical evidence, not merely an exudate or trade name.
Scope
+ Identification of living plants using foliage, flowers, fruits and supporting provenance
+ Plant establishment, growth, reproductive state and seasonal observations
+ Site suitability and responses to water availability, drainage and cold exposure
+ Plant health, damage and recovery following disturbance or management
+ Propagation provenance and the biological suitability of plants for mastic production
- Other Pistacia species and hybrids as independently identified taxa
- Harvested mastic resin, essential oils and processed products as materials
- Medical efficacy, dosage and food-product certification
- Whole Mediterranean shrubland ecosystems and landscape fire management
- Commercial appellations, supply chains and ownership rights beyond links needed for plant management
Characteristics
- Identification confidence
- unassessed | provisional | supported | disputed Controls whether species-specific management can proceed or expert identification is needed.
- Leaf architecture
- leaflet-pair count; terminal leaflet present/absent; rachis winged/unwinged; atypical/uncertain Records visible evidence for identification and flags plants needing comparison with related taxa.
- Plant dimensions
- height and crown spread in m; stem diameter in cm at a stated measurement position Supports repeatable growth assessment and decisions about spacing, pruning and access.
- Observed reproductive sex
- male | female | undetermined | atypical observation requiring review Supports propagation and fruiting assessments without inferring sex from fruit absence.
- Phenological state
- dated observations of shoot growth, flowering, fruit development and fruit colour Allows local seasonal comparisons without assuming a universal flowering calendar.
- Propagation provenance
- link to seed source, mother plant, cutting source, nursery accession or documented planting stock Separates verified origin and lineage from unsupported cultivar or resin-production claims.
- Root-zone water condition
- soil volumetric water content in % with depth and method; saturation duration in hours Helps distinguish water deficit from persistent wetness when investigating poor condition.
- Cold exposure
- minimum temperature in °C; exposure duration in hours; observation location Links actual exposure to damage and recovery rather than treating a generic hardiness rating as a plant-specific guarantee.
- Crown and bark condition
- dated leaf loss, discolouration, dieback, wounds, exudation and recovery observations Provides evidence for diagnosis and for deferring further cutting or harvesting.
- Resin collection performance
- g per plant per collection interval, with method, wound history and collection conditions Makes yield interpretable alongside plant condition and management intensity.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 17 findings · 32 questions.
Lentisk identity Evidence that a plant belongs to the registered species and the limits of that determination.
A nursery label, common name or resin-producing habit alone cannot establish the biological identity needed for later decisions.
Diagnostic organs
Observable leaf and reproductive characters used in identification.
Leaf and flower evidence
Require photographs or specimens showing complete leaves and available reproductive organs, with atypical characters recorded explicitly.
- Do several mature leaves show paired leaflets, no terminal leaflet and a winged central axis? definition
- What flowering, fruiting or seasonal foliage observations support or contradict the proposed identification? measurement
Taxonomic and stock boundaries
Separation of species identity from related taxa and horticultural stock claims.
Determination and lineage
Keep the species determination separate from claims about hybrids, cultivars or Chios-associated planting stock.
- Which botanical determination, voucher or documented accession supports this plant's identification? provenance
- What evidence excludes another Pistacia taxon or a hybrid when observed characters are intermediate? boundary
- Does a Chios or cultivar label identify documented propagation stock, geographic origin or merely a seller's description? provenance
Site and establishment Fit between a lentisk plant, its growing site and its stage of establishment.
Species-level cultivation guidance must be interpreted through local conditions and the condition of the planted material.
Exposure and root zone
Evaluate light, shelter and drainage; RHS cultivation guidance specifies sunny, sheltered conditions and sharply drained soil. [RHS cultivation](https://www.rhs.org.uk/plants/25153/pistacia-lentiscus/details)
Local site fit
Record the exposures and root-zone conditions that must be checked before planting or relocating lentisk.
- What light exposure, minimum temperatures and cold-event durations occur at the proposed planting position? measurement
- How long does the root zone remain saturated after rain or irrigation, and what evidence supports its suitability? measurement
Establishment trajectory
Distinguish newly propagated or transplanted plants from established shrubs when interpreting water needs and growth.
Rooting and water support
Base changes in establishment care on observed rooting, growth and stress rather than the drought-resistance label alone.
- When and how was this plant propagated or transplanted, and what was its initial root condition? provenance
- What monitored growth and water-status evidence would justify reducing or increasing supplemental irrigation? action
Reproduction and propagation Flowering sex, fruit development and traceable production of new lentisk plants.
Reproductive observations affect fruiting expectations, while propagation choices determine what lineage information can be retained.
Flowering and fruit set
Record reproductive evidence at the plant and local stand levels.
Sex and reproductive outcome
Keep sex determination, flowering overlap, fruit set and seed viability as separate observations.
- Which observed flowers establish the plant's sex, and on what dates were they examined? measurement
- If a female plant sets little fruit, what evidence distinguishes flowering mismatch, limited pollen availability and other causes? definition
- What proportion of sampled fruits contains viable seeds rather than merely showing mature external colour? measurement
Propagule origin and performance
Trace source plants and evaluate propagation outcomes; RHS lists seed and softwood cuttings as propagation routes. [RHS propagation](https://www.rhs.org.uk/plants/25153/pistacia-lentiscus/details)
Traceable new plants
Preserve the distinction between seed-derived offspring and vegetatively propagated material when making identity and performance claims.
- Which source plant or seed collection produced this batch, and which parentage details remain unknown? provenance
- Which treatment and growing conditions produced measured germination or rooting success for this source material? measurement
- Does the intended use require vegetative continuity with a selected plant or a documented range of seed sources? action
Condition and recovery Interpretation of lentisk decline, physical damage and subsequent recovery.
Visible symptoms need causal investigation before an agent changes watering, removes branches or resumes harvesting.
Decline investigation
Connect foliage and root symptoms with exposure history and diagnostic evidence.
Symptom-cause separation
Record symptoms independently from proposed causes and preserve competing explanations until supported.
- Where and when did discolouration, leaf loss or dieback begin relative to cold, irrigation changes or transplanting? provenance
- What inspection or diagnostic evidence distinguishes root damage, water stress and a biotic cause? measurement
Damage and regrowth
Plant response following pruning, browsing, fire or bark injury.
Intervention and recovery record
Assess observed regrowth and wound condition without assuming every plant or damage type has the same recovery capacity.
- What tissue was damaged or removed, how extensively, and what basal or crown regrowth subsequently occurred? measurement
- Which recovery observations justify further pruning or harvesting, and which require deferral? action
Mastic production interface The living plant's suitability for resin collection and the boundary between plant management and harvested material.
Mastic production requires attention to source identity, bark injury and recovery without extending plant identity into unsupported product claims.
Harvest candidate and protocol
Evidence needed before applying a resin-collection method to a particular plant.
Plant-specific harvest suitability
Treat stock selection, plant condition and collection technique as matters requiring documented local evidence.
- What documented experience supports resin collection from this planting stock, size class and growing location? provenance
- Which protocol specifies incision placement, timing, frequency and conditions for stopping collection? action
- Do existing wounds, crown decline or recent stress make the plant unsuitable for the proposed collection cycle? action
Yield and material handoff
Link measured output to its source plant while handing material quality and processing to neighbouring models.
Traceable resin output
Retain collection provenance and plant response without treating species identification as proof of resin grade or geographic certification.
- What resin mass was collected from each plant over a stated interval, using what method and with what subsequent wound response? measurement
- At what collection event does the resin become a separately tracked material batch linked back to this plant? boundary
- Which product-origin or quality claims require evidence beyond the source plant's species identity? boundary
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
