'''''Microdesmia rigida''''', the '''oiticica''',<ref name=IUCN/> is a species of plant in the family [[Chrysobalanaceae]]. It is [[Endemism|endemic]] to Brazil.<ref name=IUCN/> The oiticica grows deep in floods of rivers and streams, forming long, narrow avenues to the edge of ravines or floodplains staining the dark-green color of its large and dense foliage.<br />
<br />
==Description==<br />
''Microdesmia rigida'' is generally considered a tree, and can reach 15 m in height. Leaves alternate, measuring 12&nbsp;cm long by 6 wide. Flowers 3&nbsp;mm in diameter, yellow, arranged in spikes branches. Fruit drupaceous, fusiform or oval, from 2–7&nbsp;cm. The rind of the fruit is green even when ripe but becomes dark yellow when dry.<br />
<br />
The wood is white and fiber interlacing, very resistant to crushing. The leaves, extremely rigid and [[Glossary_of_botanical_terms#coriaceous|coriaceous]], lend themselves to polishing artifacts of horn. Its value, however, in the past, derived from its seeds, rich in oil (60%) suitable for paint and varnish. On average, a foot of Oiticica produces 75&nbsp;kg of nuts per season, but exceptionally, examples were recorded with production of up to 1,500 kilograms.<br />
<br />
==Cultivation==<br />
The oiticica nuts are used to make oiticica oil (Brazil). Oiticica oil finds limited use as a substitute for tung oil or linseed oil when the price of either of these products prohibit their use. Oiticica oil is much darker in color and is susceptible to transforming into a pasty, semi-solid state at room temperature. This requires heating prior to use.<ref>{{cite web | url = http://www.campbell-uv.com/dryingoils.html | author = Campbell and Co. | title = Drying Oils | access-date = 2009-03-02 | archive-url = https://web.archive.org/web/20141220210634/http://www.campbell-uv.com/dryingoils.html | archive-date = 2014-12-20 | url-status = dead }}</ref><br />
