Quercus minima is one of the most distinctive oaks of southeastern United States in morphology, habit, and habitat. It is one of our most strongly rhizomatous species, and it flowers and fruits as early as three years from seed, on vertical stems as small as 0.2-0.3 m. Other related live oaks of Quercus series Virentes (see C. H. Muller 1961) can produce rhizomatous clonal patches as well, but these typically do not bear fruit, are usually associated with large shrub or tree forms, and probably represent response to fire and/or drought conditions. Because of the juvenile phases in other live oaks that may resemble Q . minima , it is necessary to evaluate form and reproductive capacity within populations to identify those species accurately.
Putative hybrid swarms between Quercus minima and Q . chapmanii occur along the eastern side of Florida. These are rhizomatous shrubs with leaves somewhat intermediate between the two parents. The leaves are broadly rounded apically and basally, and sparsely stellate abaxially. The fruit resembles that of Q . minima . Material of such affinity, but with larger nuts (to 25 mm), was the basis for Q . rolfsii Small. More data on variation in cotyledon fusion in the putative hybrid swarms would be useful because Q . minima has connate cotyledons and those of Q . chapmanii are distinct.
Quercus minima has been reported from coastal Texas (C. H. Muller 1970), but that material is probably best referred to Q . fusiformis and possible introgressants from Q . virginiana and Q . oleoides . Typical Q . minima is not known from west of Mississippi. The Texas populations that have been referred here lack leaf dimorphism, leaf shape, and venation of Q . minima . Instead, they seem to be part of an extremely variable complex of erect shrubs, rhizomatous shrubs, and trees that have leaves varying in form between those of Q . fusiformis and Q . oleoides (e.g., the type of Q . oleoides var. quaterna C. H. Muller). If Q . minima occurred on the Texas coast in the past, its presence there has been so diluted by introgression that it is not now recognizable by the very distinctive and reliable characteristics that are used to identify it.

Quercus minima, o roure nan viu, pertany a la família de les fagàcies. Està dins de la secció dels roures blancs del gènere Quercus.
Descripció
Quercus minima és un tipus de roure de rizomes. El creixement és semblant a un arbust, amb el que comunament es formen extenses colònies clonades. Les fulles són alternes, simples i senceres o amb dents irregulars o lòbuls. Els lòbuls, quan estan presents, solen ser la columna vertebral de punta. Les fulles es mantenen durant tot l'hivern, caient just abans o quan es reprengui el nou creixement a finals de l'hivern o principis de primavera.
Hàbitat
És natiu als estats del sud-est dels Estats Units, des de Louisiana (possiblement a Texas[1]), cap a l'est a Florida i cap al nord, al llarg de la plana costanera de Virgínia[2]

Quercus minima, the dwarf live oak or minimal oak, is a North American species of shrubs in the beech family. It is native to the southeastern United States. It is placed in the southern live oaks section of the genus Quercus (section Virentes).[4]
Quercus minima is an evergreen or semi-evergreen shrub rarely more than 2 metres (6+1⁄2 feet) tall, reproducing by seed and also by means of underground rhizomes. It commonly forms extensive cloned colonies with many stems, many of them unbranched. The leaves are alternate, up to 12 centimetres (4+1⁄2 inches) long, and toothless or with irregular teeth or lobes. The lobes, when present, are usually spine-tipped. The leaves are retained through the winter, dropping just before or as new growth resumes in late winter or early spring.[5]
Quercus minima is native to the coastal plain of the southeastern United States, primarily in Florida but extending from there to the Carolinas and eastern Louisiana.[6] There are reports of the species also growing in Texas, but these populations appear to belong to other taxa.[5][7]

Las hojas se mantienen durante todo el invierno, cayendo justo antes o cuando el nuevo crecimiento se reanude a finales del invierno o principios de primavera.

Es nativa del sureste de Estados Unidos desde Louisiana (posiblemente Tejas[1]) hacia el este hasta la Florida y hacia el norte a lo largo de la planicie costera de Virginia.[2]
