Mountain holly (Ilex mucronata)

Description

“Pet poisonous” – Toxic parts: berries Ilex mucronata, the mountain holly or catberry, is a species of holly native to eastern North America, from Newfoundland west to Minnesota, and south to Maryland and West Virginia. It was formerly treated in its own monotypic genus as Nemopanthus mucronatus (L.) Loes., known as "false holly", but transferred to Ilex on molecular data; it is closely related to Ilex amelanchier. Ilex mucronata is a deciduous shrub growing to 3 m (rarely 4 m) tall (or 6 to 10 feet high from the "Manual of Woody Landscape Plants" by Dr. Michael Dirr.) The leaves are alternate, simple, elliptic to oblong, (1 to 2.5" long and 3/4's as wide) 1.5–7 cm long and 1–3 cm broad, with an entire or finely serrated margin and an acute apex, and a 0.5–2 cm (1/4 to 1/2" long) petiole. The tiny flowers about 1/5" in diameter with 4 to 5 petals are inconspicuous, whitish to greenish-yellow, produced on slender peduncles 25 mm or more long; it is usually dioecious, with male and female flowers on separate plants. The fruit is a red drupe 6–7 mm (1/4 to 1/3") diameter containing three to five pits.
