Campomanesia hirsuta is a semideciduous tree of the Atlantic Forest in Rio de Janeiro state, Brazil. It is associated with humid, very well-drained mountain slopes and is described as growing 3–7 m tall. [1][3][4]
An account of the species treats it as Endangered and places its known historical range near Petrópolis and Teresópolis, where only a few wild trees were known and none had been seen since 1968 in the conservation description. Authenticated cultivated material is therefore preferable to wild collection. [3]
Description[edit | edit source]
The tree is more or less pyramidal, with a reported height of 3–7 m and a bole about 15–25 cm across. It is semideciduous, so some seasonal leaf loss is part of its documented habit. Its known range is restricted to mountainous Atlantic-rainforest settings in Rio de Janeiro state. [3][4]
The fruit is a green, globose berry reaching up to 7 cm in diameter. [3]
Cultivation[edit | edit source]
Campomanesia hirsuta comes from humid mountain rainforest slopes but is also described as suitable for home gardens. Cultivation guidance calls for some shade and characterizes growth as slow. In a collection, combine sheltered humidity with a root zone that drains freely, and treat conservation-sensitive provenance as part of the planting decision. [3]
Soil and water[edit | edit source]
As a habitat-level inference, begin with a freely draining medium that does not remain saturated after irrigation. The species is associated with very well-drained mountain slopes, while the exact soil texture, acidity, organic-matter requirement, and irrigation interval should be confirmed from authenticated cultivated plants rather than borrowed from another species. [3]
Sun and humidity[edit | edit source]
Provide partial shade or filtered light with good airflow. This follows the species-specific cultivation note for some shade and the humid mountain-rainforest setting; it should not be read as a fixed shade percentage or a universal full-sun limit. [3]
Seasonal changes[edit | edit source]
The semideciduous habit indicates seasonal leaf turnover. As a habitat-level inference, keep moisture available during active growth while avoiding prolonged wetness around the roots, and adjust watering to local rainfall and the plant's observed leaf cycle rather than using a fixed calendar. [3]
Propagation[edit | edit source]
Sow ripe seed promptly in a nursery seedbed under partial shade. The propagation account gives germination above 90% and sprouting in 30–40 days, while seedlings are described as slow growing. These figures are attributed there to Lorenzi's Brazilian Trees, volume 3 (2009), and should be treated as a reported protocol for fresh, authenticated seed rather than a guaranteed result for every seed lot. [3]
Flowering, fruiting, and harvest[edit | edit source]
The species produces green, globose berries up to 7 cm in diameter. [3]
Fruit and uses[edit | edit source]
The fruit is described as acidic and suitable for eating raw or cooked. The same account mentions jellies and juices as uses. [3]
