Help with IDs? Solved!

Does anyone recognize either or both of these woody/shrubby plants that have showed up in the Meadow?

Thorns! Perhaps bluewood condalia? Definitely gum bumelia (see below).

No thorns. A yaupon? Very likely! Yay!

Sample leaves from both plants....

From Joe Marcus, living collections manager at the Lady Bird Johnson Wildflower Center: "I’m going to have to agree with Anonymous and say it’s gum bumelia (Sideroxylon lanuginosum). The spurs visible in your picture are not always present, but some trees will be studded with them.  Growing conditions and growth rate could be factors in their formation. The other plant does appear to be Ilex vomitoria."

This is going to get interesting.

Jason Singhurt, a plant ecologist/botanist with Texas Parks and Wildlife Department, says, "The first plant is gum bumelia, and the second one is deciduous holly." 

I'm good either way! 

Yaupon holly (Ilex vomitoria) or possumhaw (Ilex decidua)
