| Our tree of the week is a lesser known native oak. It is found in isolated areas of the deep south and parts of Texas. In the arboretum, we have it labeled as Durand oak (Quercus durandii), but it seems the nomenclature and signage is out of fashion. The current dominant scientific name is Quercus sinuata. Among people who might know a thing or two about our southern oaks, the tree also goes by the impolite name of 'bastard oak.' |
 |
| The arboretum's singular Durand oak is pictured center. Its slender trunk is distinct, while its foliage blends in with the surrounding greenery. In February of 1998, Professor Ed Leuck acquired this specimen from John Mayronne of Covington, Louisiana. The following autumn it was planted in this full-sun location, which isn't too far uphill from one of the arboretum's main drainage channels. |
 |
| The Durand oak is in the white oak group. Its leaves are simple, lobed, dark green, and smooth. |
 |
| Beneath, leaves are pale green. |
 |
| Leaves measure approximately 4 inches in length. |
 |
| Durand oak leaves vary in shape, and they are often asymmetrical. |
 |
| The arboretum's Durand oak is more than twenty years old. It is still short in stature, but this week we noticed that the little oak tree is growing up. Immature fruits were spotted on its branches. |
 |
| We will keep an eye on these young acorns as they develop over the summer. Hopefully we can snap pictures of the mature fruits in the fall. |
 |
| The dark gray trunk bark is rough, but most branches still have relatively smooth bark. |
