You’re hiking along and barely brush the edge of this shrub and it gets you! Because of this, the Cat Claw Acacia (Acacia greggii) is also known as the “wait a minute bush”. The claws are hard to spot because they are only 1/8th to 1/4rd of and inch and they hide on the underside of the branches.
This morning I noticed some new growth and saw that the claws are red.
