Overcup Oak
Quercus lyrata
Overcup oak is fairly easy to identify. The acorns are almost completely covered by their knobby cups. The leaves have long, narrow lobes and wide sinuses. In Missouri, it grows naturally only in wet forests along the Mississippi and Meramec rivers.

Fragrant Sumac
Rhus aromatica
Unlike its cousin poison ivy, fragrant sumac is a peasant, nontoxic plant. Note the middle leaflet of its "leaves of three": On fragrant sumac, there is no (or at most a very short) leaf stalk on that middle leaflet. Also, fragrant sumac has hairy, reddish fruits (not waxy whitish ones).

White Mulberry
Morus alba
White mulberry was introduced from Asia for its berries and as fodder for an attempted silkworm industry. Birds have helped spread white mulberry so much that in many places it is more common than our native red mulberry.

About Trees, Shrubs and Woody Vines in Missouri

There are no sharp dividing lines between trees, shrubs, and woody vines, or even between woody and nonwoody plants. “Wood” is a type of tissue made of cellulose and lignin that many plants develop as they mature — whether they are “woody” or not. Trees are woody plants over 13 feet tall with a single trunk. Shrubs are less than 13 feet tall, with multiple stems. Vines require support or else sprawl over the ground.
