|discussion=<p><i>Quercus minima</i> 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 <i>Quercus</i> 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 <i>Q. minima</i>, it is necessary to evaluate form and reproductive capacity within populations to identify those species accurately.</p><!--
--><p>Putative hybrid swarms between <i>Quercus minima</i> and <i>Q. chapmanii</i> 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 <i>Q. minima</i>. 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 <i>Q. minima</i> has connate cotyledons and those of <i>Q. chapmanii</i> are distinct.</p><!--
--><p><i>Quercus minima</i> has been reported from coastal Texas (C. H. Muller 1970), but that material is probably best referred to <i>Q. fusiformis</i> and possible introgressants from <i>Q. virginiana</i> and Q. oleoides. Typical <i>Q. minima</i> is not known from west of Mississippi. The Texas populations that have been referred here lack leaf dimorphism, leaf shape, and venation of <i>Q. minima</i>. 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 <i>Q. fusiformis</i> and Q. oleoides (e.g., the type of Q. oleoides var. quaterna C. H. Muller). If <i>Q. minima</i> 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.</p>
