Its source is unknown, but it is possibly from an historic medicinal garden. The tree is spreading rapidly, and has invaded pastures, gulches and closed-canopy alien and mixed alien-ohia forest in North Kohala.

First noticed by field workers in North Kohala about ten years ago, swizzle stick has become a growing concern within the past year, as the tree has spread rapidly and invaded pastures, gulches, and closed-canopy alien and mixed alien-‘ōhi‘a forest in North Kohala, where it grows under the canopies of eucalyptus, strawberry guava, common guava, kukui, albizia, and ‘ōhi‘a. The current distribution is from 180–490 m (600–1600 ft) elevation, from Makapala to ‘Iole. It has not yet been reported in the native forest mauka of its current infestation, nor has it been detected in the adjacent Kohala State Forest Reserve or the Pu‘u o Umi Natural Area Reserve, but no surveys have yet been conducted. The source area is unknown but could possibly be a historic medicinal garden in the area. Rauvolfia vomitoria is a shrub or tree 0.5–20.0 m tall with leaves in whorls of 3–5; the blades are elliptic, sometimes narrowly so, 3.4–27.0 cm long, 2–9 cm wide, apiculate, with 8–17 pairs of arcuate-ascending secondary veins; the petiole is 6–35 mm long. The inflorescence consists of up to 4 whorls of dense, 15–450 flowered cymes, the inflorescence branches puberulent. The flowers are fragrant, 5-parted, greenish white to yellow; the tube 5.8–10.0 mm long, glabrous outside, the corolla lobes 1.1–2.1 mm long. The drupes are bright orange or red, globose to ellipsoid, 8–14 mm long, up to 9 mm in diameter, with usually only one mericarp developing (omino 2002; Li et al.
