Discussion
P. juliflora var. glandulosa (Torr.) Cockerell P. chilensis var. glandulosa (Torr.) Standi. Neltuma glandulosa (Torr.) Britt. & Rose N. constricta (Sargent) Britt. & Rose N. neomexicana Britt. Distribution as key. Rocky slopes, plains, alluvial soil along streams, desert scrub. Abundant, often dominant and forming “woodlands” over thousands of acres. April-May (June). Except for a few populations of var. torreyana and the single station for P. laevigata, var. glandulosa is the only mesquite east of the Pecos River. Sporadically present in trans-Pecos Texas, it is there usually distinct from var. torreyana. I have treated the mesquites of the Mesilla Valley in southern New Mexico largely as var. glandulosa; however, sensu characters they are variously intermediate between it and var. torreyana. Collections of var. glandulosa from Arizona and California are presumed to represent introductions.
