About plant names...

Burro bush is common in the American southwest and northwestern Mexico. Its roots grow away from those of similar species, to reduce contention for water. Creosote bush, common in the same habitats, secretes a chemical that inhibits the growth of burro bush.

Identification: Burro bush reaches up to 3' (91 cm) in height. It has many fine branches, almost resembling a porcupine. The leaves are very irregular in shape, and pale green. They remind me of lichen. Flowers are small and yellow. The seeds, which may be yellow, purple, or brown, are round in shape and sharp-pointed, like burs.
