Description
“Trees or shrubs, usually with imperfect flowers. Leaves simple, entire, serrate, dentate or crenate; stipules obsolete. Flowers axillary, solitary, fascicled or in cymes, 4-7 merous, 4-8 mm broad; petals united at the base, imbricate in bud; pistillate flowers usually with nonfunctional stamens; anthers opening lengthwise; stigmas 4-7, essentially sessile. Drupe red, black or rarely yellow or white. Seeds with hard, bony endocarp (pyrenes), often grooved or ribbed on the back, 4-7 in a fruit, 1 in each locule.” [1]
"Rhizomatous shrub to 3m tall, usually forming extensive colonies, twigs puberulent. Leaves evergreen, obovate to elliptic, 2.5-6.5 cm long, crenate, but usually only toward the apex, the last pair of teeth usually directly opposite each other, glabrous, lustrous above; petioles 38 mm long, canescent. Pedicels 1-5 mm long, appearing longer when single fruited (careful examination shows that the lower part is peduncle). Staminate flowers in axillary, 3-7 flowered, pedunculate cymes. Pistillate flowers axillary, solitary or in 3-flowered, pedunculate cymes. Flowers 5-7 merous. Drupe black, dull or slightly lustrous, globose, 5-7 in diam.; pyrenes 5-7, smooth, 3-4 mm long." [1]
Distribution
Ilex glabra is distributed from Nova Scotia and Maine south to Florida and west to Texas.[2]
Ecology
Habitat
Ilex glabra can be found in "savannas, pine flatwoods, pocosin margins, swamps, primarily in wetlands, but extending upslope even into sandhills, with a clay lens or spodic horizon below to maintain additional moisture."[2] It is restricted to native groundcover with a statistical affinity in upland pinelands of South Georgia. [3] In the Atlantic and Gulf Coastal Plain, this species is listed by the USDA Natural Resources Conservation Service as a facultative wetland species that mostly occurs in wetland habitats, but can also occasionally be found in non-wetland habitats.[4]
Phenology
Generally, I. glabra flowers from May until June and fruits from September until November.[2] It has been observed to flower from April to June with peak inflorescence in May.[5]

Use by animals
It consists of approximately 5-10% of the diet for various large mammals, small mammals, and terrestrial birds.[7]
Conservation and management
This species is listed as threatened by the Connecticut Department of Environmental Protection and by the Maine Department of Conservation, Natural Areas Program. It is also listed as exploitably vulnerable by the New York Department of Environmental Conservation, Division of Land and Forests, and is listed as extirpated by the Pennsylvania Department of Conservation and Natural Resources.[4]
