About Acanthosyris spinescens (Mart. & Eichler) Griseb.
Acanthosyris spinescens (Mart. & Eichler) Griseb. is locally known by the common names Sombra de touro and quebradillo. It is a spiny, native tree, with a native distribution across Uruguay, Argentina, and Brazil. As a pioneer species, it grows successfully in newly established forest areas in semi-shaded conditions, and it grows slowly overall. This tree produces yellow edible fruit, and its leaves are used in traditional medicine to treat fevers and ulcers. It was first formally documented in 1879, published in Abh. Königl. Ges. Wiss. Göttingen 24: 151 (1879).
