'ie'ie Freycinetia arborea

Native

'ie'ie is a perennial vine native to Hawaii. It grows to 5 ft.

More about this plant

Freycinetia arborea, or ʻIeʻie, is a densely branched, brittle, woody climber in the family Pandanaceae, endemic to the Pacific Islands. ʻIeʻie is found in moist forest on the Hawaiian, Marquesas, Austral, Society, and Cook Islands. It grows into the forest canopy, attaching itself to a host tree using aerial roots. It may also grow as a sprawling tangle on the forest floor. 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

1 / 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.

Caterpillar host 1

Deep dive

Caterpillar host · 1/5 — 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.

Counts are genus-level and banded 0–5. Full rubric →

Deep dive — what these mean

Seed mass 32 mg — average weight of one seed. Bigger seeds are easier to hand-collect & direct-sow; dust-fine seeds need surface-sowing.

Leaf nitrogen 17.1 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, 13.6 mm²/mg)

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

Mycorrhiza AM — the root–fungus partnership it forms (AM = most plants; ECM = most forest trees; ERM = heaths; NM = none). Trades sugars for water & nutrients via shared soil networks.

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