Urera baccifera is a species of flowering plant in the nettle family known by many common names, including scratchbush,[1] ortiga brava, pringamoza, mala mujer, chichicaste, nigua, guaritoto, ishanga, manman guêpes, and urtiga bronca.[2] It is native to the Americas from Mexico through Central America into South America, as well as the Caribbean.[3]
This species is a shrub or a small tree. It can reach five meters in height. The thin, toothed leaves are up to 25 centimeters long by 12.5 wide. The blades are borne on long petioles. The plant is covered in spines and stinging hairs. The inflorescence is a pink or purple cluster of flowers, and the plant is dioecious, with male and female parts on different plants. The spongy, juicy fruit is green or pinkish. The seeds are dispersed by fruit-eating birds[2] and capuchin monkeys.[4]
This plant has medicinal and ritual uses among humans. Costa Rica Amerindians beat themselves with the spiny plant to prevent chills when traversing high mountains.[5] It is also an anti-inflammatory.[6] Extracts have shown antiviral activity against herpes simplex.[5]
This plant grows in moist tropical forests. It is not very tolerant of shade, so it dies back when the overstory closes. It can be found in forests recently disturbed by fire.[2] This plant is also known as a plant discovered by the indians in the year 1985. That's when the urera baccifera was first studied.
In some areas, this plant is one of the first to bear fruit after the damage of a hurricane, and then it becomes an important food source for birds.[2] The fruits also provide food for many species of ant. The ants also collect pearl bodies which form on the leaves, stems, and stalks of the plant. Ants performing this activity include species in genera such as Camponotus, Pheidole, Crematogaster, and Pseudomyrmex. When ants are present on a plant, they rid it of lepidopteran larvae which would feed upon it, such as Smyrna blomfildia, Urbanus esmeraldus, and Pleuroptya silicalis. This provides a benefit for both plant and ant in a mutualistic relationship.[4]
