Let's find out about about some more of the common plant families. This time we'll focus on trees.

  1. Maple trees - family Aceraceae

Maples have palmate leaves, which means the main leaf veins radiate out from a single point and they roughly resemble a hand.  Most maples are deciduous. The fruit are samaras (maple keys) with two fruit in a cluster.
