Ilex mucronata (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.[1]

Taxonomy

It was formerly treated in its own monotypic genus as Nemopanthus mucronatus (L.) Loes., but transferred to Ilex on molecular data;[2] it is closely related to Ilex amelanchier.[3]

Description

Ilex mucronata is a deciduous shrub growing to 3 m (rarely 4 m) tall. The leaves are 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 petiole. The flowers 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 diameter containing three to five pits.[4][5][6]

The name Mountain Holly is also sometimes used for the related Mountain Winterberry (Ilex montana).

The white-petaled flower shown here, supposedly of Ilex mucronata, and the 2nd image, showing a flowering shrub of the same species, are actually images of an Amelanchier (Rosaceae) and nothing like the unisexual, very small, flowers of Ilex mucronata (Aquifoliaceae).
