| Viscid Acacia, Varnish Acacia|
Viscid acacia has a very sparse silhouette, with few branches that grow upright. The name comes from the sticky secretions that cover the entire plant. It is closely related to whitethorn acacia (A. constricta), differing in the number of leaflets (constricta's 4-7 pairs of primary leaflets vs. neovernicosa's 1-2) and neovernicosa's pairs of half-inch spines on the branches. Both are common in the Trans Pecos, growing in sunny locations on rocky, primarily limestone hillsides. Viscid acacia is hardy to 0 degrees F. and is very drought tolerant.
