Colubrina greggii is a species of flowering plant in the buckthorn family, Rhamnaceae, that is commonly known as the Sierra Nakedwood[1] or Gregg's Colubrina. It is native to the lower Rio Grande Valley of Texas in the United States,[2] eastern Mexico,[3][4] and Guatemala.[5] It is very similar to C. arborescens of Southern Florida and the Caribbean, and herbarium specimens of the two species are difficult to distinguish.[6]

Description

C. greggii is a shrub 2–3 m in height or a small tree, reaching 5 m. Stems are densely pubescent. Leaves are alternately arranged, simple, ovate to lanceolate-ovate or elliptic-ovate, and have finely toothed margins. The blades measure 6–18 cm in length and 3–8 cm in width. The inflorescence is a thyrse with 20-80 flowers. Peduncles measure 5–12 mm in length. The flowers are greenish-yellow, with stamens opposite the spoon-shaped petals. Flowering takes place in the summer and fall. The fruit is a hard, globose capsule approximately 7 mm in diameter, on which calyx remnants form an equatorial ring.[2][4][7][8]
