GENUS INDEX
GENUS CODE: QUERC GENUS SCIENTIFIC:Quercus GENUS AUTHORITY: L. GENUS COMMON: Oak GENUS SUMMARY: A genus of about 350-530 species, trees and shrubs, of temperate, subtropical, and rarely tropical regions of the Northern Hemisphere. Oaks are the predominant tree of our area, with a variety of species dominating much of the landscape in nearly every ecological situation. Only in a few specialized (and usually in some sense edaphically extreme) communities are oaks generally entirely absent: deepest Coastal Plain swamps, some Coastal Plain depression ponds, wettest pine savannas, pocosins, spruce-fir forests, highest elevation northern hardwood forests, and mountain bogs. GENUS IDENTIFICATION: Identification notes: Many oak species are well-adapted to ecological situations in which fires frequently burn the ground layer. Fire-maintained communities of the Piedmont and Mountains typically have oaks such as Q. stellata, Q. marilandica var. marilandica, Q. ilicifolia, and Q. prinoides. The two latter species are normally shrubby, and have become rarer because of fire suppression (they require fire to prevent larger trees from outcompeting them). In contrast, Q. stellata and Q. marilandica var. marilandica become larger and more frequent in fire-suppressed conditions.

Plant Sale Text: Native to poorly-drained lowlands, this southeastern oak has gained popularity in recent years as a street tree. Like many other bottomland tree species, overcup oak tolerates wet, poorly drained soil conditions as well as much leaner, drier sites. The distinctive cap of the acorn of Q. lyrata covers most of the nut. The narrow, lobed leaves of this species are also readily identifiable. The genus Quercus supports up to 518 species of lepidoptera.

SCIENTIFIC NAME: Quercus lyrata
COMMON NAME: Overcup Oak
SYNONYMY: [= C, F, FNA, G, GW, K, Mo, RAB, S, Va, WH3]
PHENOLOGY: Mar-Apr; Sep-Oct (of the same year).
HABITAT: Seasonally rather deeply and frequently flooded soils of floodplains of the Coastal Plain, less commonly in seasonally flooded swamps in Triassic basins in the lower Piedmont, and rarely in upland depression swamps of the Piedmont (developed over clays weathered from mafic rocks) and Coastal Plain.
COMMENTS: Primarily a species of the Southeastern Coastal Plain: DE south to Panhandle FL, west to e. TX and se. OK, north in the inland to w. TN, s. IN, s. IL, and se. MO. Of our oaks, Q. lyrata tolerates the wettest habitats, both in terms of depth and duration of flooding.
