Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

ANSWER:

The growths that you are seeing are called fasciations.  Sophora secundiflora (Texas mountain laurel) seems particularly susceptible to this growth anomaly.  Here is a discussion about fasciation from a recent question to Mr. Smarty Plants.  They aren't harmful to the tree—just fascinating fasciations!
