Present on Pacific Islands?  yes

Primarily a threat at high elevations?  no

Common name(s): [more details]

English: bird's-eye bush, Mickey Mouse plant

Habit:  shrub/tree

Description:  "Shrub or small tree (1) 2-5 (6) m. high, evergreen, with bark rather rough, greyish-white; branches slender or rather stout, ± spreading, reddish-purple or brownish with prominent lenticels at first, becoming greyish-white. Leaves petiolate; lamina (5) 6.5-11.2 x 2.6-5.1 cm. (up to 21 x 7 cm. in E. Africa), elliptic or oblong-elliptic to narrowly obovate, obtuse to rounded and mucronate at the apex, with margin entire or slightly undulate, usually beset with numerous equal dark-tipped cilia, cuneate to cordate at the base, ± coriaceous, with main lateral nerves more prominent than subsidiary ones and densely reticulate tertiary venation prominent above but almost plane below; petiole 4-5 (6) mm. long, slender to stoutish, sometimes rather swollen. Flowers 3-c. 20 in ± condensed panicles terminating short lateral shoots; pedicels 1-2.5 cm. long in fruit, articulated about 1/4 the distance from the base. Sepals 10-14 mm. long in flower, elliptic to elliptic-oblong, rounded, becoming red, 12-16 mm. long, flat and spreading in fruit. Petals bright yellow, sometimes dark-veined, 15-25 x 10-18 mm., obovate to broadly elliptic, unguiculate. Stamens with anthers 4-5 mm. long, equaling or half as long as the filaments, frequently incurved, dehiscing by apical pores. Carpels (8) 10-12, with styles free at the apex and spreading; stigmas capitate. Drupelets 9-10 x 5.5-8 mm., flattened-cylindric, inserted near the base; embryo straight." (Flora Zambesiaca online [cited by/included in JStor Global Plants entry for Ochna kirkii])

Compared to Ochna thomasiana, Ochna kirkii "has larger leaves (2-3.25 inches long, 0.75-1.25 inches wide) that are broadly oblong, oblanceolate, or obovate, provided with many cilia around the margin on mature leaves; and smaller fruiting sepals (0.4-0.5 inch long, 0.15-0.25 inch wide).  Young leaves of O. thomasiana are ciliate around the entire margin, but at maturity only 5-8 cilia persist near the blade base" (Staples & Herbst, 2005; p. 437).

Habitat/ecology:  In the shrub layer of evergreen forest and in evergreen scrub, 0-600 m. (Flora Zambesiaca online [cited by/included in JStor Global Plants entry for Ochna kirkii])

Propagation:  Seed, probably spread by birds.
