Habit:  shrub

Description:  "Medium-sized tree to 18 m high, often large epiphytes; branchlets slender; latex moderate, white; petioles 8-20 mm long, slender, narrowly margined; leaf blades subcoriaceous, elliptic to elliptic-oblong, apex acute to obtusish, base acute, lateral veins at angles of 75-80 and distally parallel; inflorescence terminal, cymose, 1-3-flowered; staminate flowers: sepals (2-) 3 pairs, decussate, the outer subpetaloid, broadly orbicular-obovate, to 3 cm long; petals 5-7, oblong-obovate, 3-4 cm long, white, rose-maculate; androphore prominent, 8-10 mm high, 12-15 mm broad, pentagonal-conic, somewhat scalloped at the summit; stamens ca 20 or fewer, commonly 2-seriate, filaments stout, terete, ca 1 cm long, outwardly curved; anthers extrorse, 4-celled, strongly coehlearform, ca 3.5 mm long; pistillate flowers: sepals 3 pairs, decussate, petals 5 (-7), oblong-obovate, ca 2.5-3.5 cm long; staminodia forming a fleshy scalloped corona 6-8 mm high and 2.5 mm thick; ovary 6-carpellate, ovules numerous, axillary; fruit somewhat ovate to somewhat obovate, 7-8 cm long, 5-6 cm broad, somewhat 6-angled; stigmas 6, sessile, acutely obovate, ca 7-8 mm long, subconnivent; seed oblong, 5-6 mm long, punctate; embryo erect, cotyledons small, hemispheric, ca 0.5 mm long." (Bassett, 1977, pp. 137-138)

Habitat/ecology:  "Trees or large epiphytes on open hillsides and pastures at 1.200-1.800 meters." (Bassett, 1977, p. 138)

Propagation:  (In cultivation) [p]ropagation is by cuttings ("From woody stem cuttings") or seed ("Allow pods to dry on plant; break open to collect seeds[.] ¶Seed does not store well; sow as soon as possible[.]"). (Dave's Garden)

Native range:  "Clusia orthoneura is an epiphytic shrub native to tropical areas of South America." (MoBot)

Comments:  "The wood of Clusia is highly durable, and is sometimes used for roof construction. The latex and the floral resin have antiseptic properties and have been used to seal wounds. Dry latex is sometimes burned like incense in churches. A few species are grown as house plants, or, in tropical areas, as ornamental trees and shrubs. Examples are Clusia rosea, C. major and C. orthoneura." (Wikipedia)

Control:  If you know of control methods for Clusia orthoneura, please let us know.
