Quercus sinuata is a deciduous tree up to 20 metres (67 feet) tall. Leaves are narrow, with shallow rounded lobes. It tends to grow in wet habitats, such as on river bluffs, river bottoms, and flatwoods, and generally over basic substrates, such as mafic rocks, shells, or calcareous sediment.
[30] Aspen trees have also been observed to explode in wildfires. [31] Steam pressure build up in tree trunks is theoretically unlikely to lead to an explosion in a rapidly moving fire front, although trees exploding after the initial front has passed or exploding through other mechanisms is entirely possible.

Quercus hypoleucoides, though usually seen as a shrub, can be found to be a full-sized tree, 9 metres (30 feet) tall in areas where it receives sufficient water. [6] [7] The tree produces its flowers in the spring as most plants do. [8] It grows in warm regions and is used as an ornamental due to its unusual foliage. [9] Bark: Is dark gray in ...
