Description

ʻĀlaʻa inhabits dry, coastal mesic, and mixed mesic forests at elevations of 240–980 m (790–3,220 ft).[3] ʻĀlaʻa reaches a height of 15 m (49 ft) and a trunk diameter of 0.4 m (1.3 ft). The thick bark is grey and fissured, with an orange inner layer. The leaves are alternate, thick, leathery, oblong or elliptical, and measure 6–14 cm (2.4–5.5 in) long and 3–6 cm (1.2–2.4 in) wide. The upper surfaces of the leaves are glabrous and shiny green, while the lower surfaces are dull and may feature bronze or reddish brown pressed hairs. The hairs are sometimes found only on the tips of new leaves (see photo gallery below). Inflorescences with one to four bell-shaped flowers are found at the bases of leaves. The fruit, a berry, is 3–4 cm (1.2–1.6 in) in diameter and yellow, orange, or purplish black. Each fruit contains one to five seeds, which are about 2 cm (0.79 in) long and yellow brown.[1]

Uses

The wood of ʻālaʻa is yellow with black streaks, extremely hard, and close grained.[1] Native Hawaiians used it in house construction and to make the pale (gunwales) of waʻa (outrigger canoes),[3] ʻōʻō (digging sticks), and ihe (spears). The sticky, milky sap was used as a kolū (glue) for weapon and tool handles[2] and as kēpau (birdlime), much like papala kepau (Pisonia spp.).[4]

Trunk
gollark: But it isn't the average, and is... maybe the sum, I can "check".
gollark: No idea, I don't actually know how it works beyond something something time domain frequency domain.
gollark: I found a video™ which explains that the peak at zero occurs because the numbers are not centered on zero.
gollark: This would be easier if I actually knew anything about which frequencies each index corresponds to, hmm.
gollark: Maybe I should take the logarithm of it instead.
