Quercus palustris IDed by a very small leaf in the crown of the tree. Being a mature tree, the bark is also an indicator of a pin oak rather than a red oak: the tree has light grey brown bark with very shallow and narrow ridges.
Gingko
Gingko biloba IDed by bullet shaped buds and tree shape.
Japanese Holly (?)
Ilex genus IDed by obovate and shallow toothed upper half of leaf margin and the leaves’ shiny green upper side.
Callery Pear
Pyrus Calleryana IDed by height (over 20ft), bark, and buds. I revisited this tree in the spring and discovered it is a cultivar of Pyrus calleryana known as a Cleveland Pear.
