Quercus nuttallii E. J. Palmer var. cachensis E. J. Palmer was described as a small-fruited form (nuts 16-18 × 12-16 mm) from specimens collected in east-central Arkansas (E. J. Palmer 1937). Noting the similarity between Q . nuttallii var. cachensis and Q . palustris , Palmer discounted the possibility of the former being of hybrid origin because (1) he had not observed Q . palustris in the type locality, and (2) the leaves and buds of the former were essentially the same as in Q . nuttallii var. nuttallii .
C. H. Muller (1942), on the other hand, argued that Quercus nuttallii was nothing more than a form [forma nuttallii (E. J. Palmer) C. H. Muller] of Q . palustris . This is a puzzling conclusion because it was based largely on the premise that Q . nuttallii occurred "...with the parent species throughout a large part of the latter's southern range (Mississippi to eastern Texas and southeastern Missouri)." The range of Q . palustris does not extend into Mississippi or eastern Texas, although its range does overlap that of Q . texana in eastern Arkansas and southeastern Missouri. E. J. Palmer (1948) and D. M. Hunt (1989) have suggested hybridization with Q . shumardii and Q . nigra , respectively. See L. J. Dorr and K. C. Nixon (1985) for an explanation of the nomenclatural confusion regarding this taxon.
Quercus texana, commonly known as Nuttall's oak,[3][4][5][6] is a fast-growing, large deciduous oak tree.
It is a tree growing up to 25 meters (83 feet) tall, with dark brown bark. It has leaves with sharp pointed lobes somewhat similar to those of the Georgia oak (Q. georgiana) and pin oak (Q. palustris).[7] It is fast-growing and usually has a pleasing red color in autumn, much more reliably so than the pin oak.
This species was for years erroneously called Quercus nuttallii, but it is now known as Q. texana; this has created much confusion with Texas red oak, which was known as Q. texana but is now known as Q. buckleyi.[8]
It is native to the south-central United States primarily in the lower Mississippi River Valley in Louisiana, Arkansas, Mississippi, Alabama, and western Tennessee. There are additional populations in eastern Texas, southeastern Oklahoma, southeastern Missouri, far western Kentucky, and the southernmost tip of Illinois.[9]
It is still relatively obscure in the horticultural industry but is slowly gaining popularity due to its fast growth rate, ease of transplanting, good fall colors and ability to grow in wet soils. It is known for its ability to rapidly recover its gas exchange after flooding.[10]
