Sapotaceae family

Star Apple Chrysophyllum cainito

Native

Star Apple is a perennial tree native to Puerto Rico. It grows to 115 ft.

More about this plant

Chrysophyllum cainito is a tropical tree of the family Sapotaceae. It is native to the Isthmus of Panama, where it was domesticated. It has spread to the Greater Antilles and the West Indies and is now grown throughout the tropics, including Southeast Asia. It grows rapidly and reaches 20 meters in height. Wikipedia →

How we know this (2) Methods & honest limits

Leaf build Direct fact

We read each species’ measured specific leaf area (leaf area per unit dry weight) from the Global Spectrum dataset and band it: thin & fast (high SLA), medium, or thick & tough (low SLA). The global median is about 10 mm²/mg.

Honest limits: A species-mean from pooled measurements — individual plants vary with light and site. A broad strategy signal, not a precise per-plant figure.

Díaz, S. et al. (2022) The global spectrum of plant form and function: enhanced species-level trait dataset. Scientific Data 9:755.

Photosynthesis Direct fact

A recorded categorical fact: each species is tagged C3 (standard), C4 (heat/water-efficient) or CAM (succulent, night-time CO₂ uptake) — or a facultative combination. We only show a trait card for the noteworthy C4/CAM cases; C3 is the unremarkable majority, kept in the data but not surfaced as a card.

Ecological value open data

3 / 5 Keystone

Keystone (host) value — caterpillar, specialist-bee & monarch hosting. A low number means “not a keystone host,” not “low value”: generalist flower-visitor value is shown separately below.

Deep dive

Caterpillar host · 3/5 — native butterfly & moth caterpillars that feed on this genus — the base of the food web (more caterpillars → more songbirds). Genus-level keystone count from Warren II 2026 (CC0; Tallamy host-use records), gap-filled by our GloBI derivation.

Deep dive — what these mean

Wood density 0.72 g/cm³ — how heavy the wood is for its size. Denser wood = hotter, longer-burning firewood and tougher poles; lighter wood rots fast (quick mulch).

Seed mass 220 mg — average weight of one seed. Bigger seeds are easier to hand-collect & direct-sow; dust-fine seeds need surface-sowing.

Leaf nitrogen 16.1 mg/g — measured leaf N. Higher = richer prunings for compost/mulch (a measured stand-in for "dynamic accumulator" claims).

Leaf build — how thick & tough the leaves are. Thin, lightweight leaves grow fast and crave light; thick, tough leaves last longer and shrug off shade, drought & grazing. (measured leaf area per dry weight, 11.1 mm²/mg)

Photosynthesis — the standard “C3” pathway most plants use, most active in cooler, moister, moderate-light conditions. (pathway C3)

Measured traits from TRY + Werner et al. (N-fix), Fan et al. (roots) & FungalRoot — general guidance, not species-specific prescriptions.
