Xylosma ciliatifolia, colloquially known as espinho-de-judeu, is a species of flowering plant in the family Salicaceae. It is native to South America.
Xylosma ciliatifolia performs well across a range of light conditions, from full sun to fairly dense, dappled shade, and exhibits a notably fast growth rate during its juvenile stages. Propagation by seed is effective when sown promptly after ripening, ideally in a nursery seedbed with partial shade. Under such conditions, germination typically occurs within 15–30 days, with an expected success rate around 50%. Controlled trials suggest that alternating temperatures of 20–30 °C (68–86 °F) and a sand-based substrate optimize seedling development. Although detailed propagation protocols were previously lacking, recent findings confirm the species' resilience: seeds maintain viability for extended periods, especially under dry storage, and consistently germinate within seven days during the initial months.
Xylosma ciliatifolia is native to a broad region, with confirmed distribution across Venezuela—including Aragua, Miranda, and the Capital District—as well as Guyana, French Guiana, Bolivia, particularly in Santa Cruz, Paraguay in the Alto Paraná region, and Uruguay. In Brazil, the species occurs across multiple regions: in the Northeast, it is found in Maranhão, Ceará, and Pernambuco; in the Central-West, in Mato Grosso and Brasília; in the Southeast, it ranges from Caldas to the Lagoa area in Minas Gerais, and also in São Paulo and Rio de Janeiro; in the South, it occurs in Paraná, Santa Catarina, and Rio Grande do Sul.
