More about this plant

Cleyera japonica (sakaki) is a flowering evergreen tree native to warm areas of Japan, Taiwan, China, Myanmar, Nepal, and northern India. It can reach a height of 10 m (33 ft). The leaves are 6–10 cm (2.4–3.9 in) long, smooth, oval, leathery, shiny and dark green above, yellowish-green below, with deep furrows for the leaf stem. The bark is dark reddish brown and smooth. The small, scented, cream-white flowers open in early summer, and are followed later by berries which start red and turn black when ripe. Sakaki is one of the common trees in the second layer of the evergreen oak forests. It is considered sacred to Japanese Shintō faith, and is one of the classical offerings at Shintō shrines including Tamagushi and masakaki. 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.
