Mesquite Flowers and Seeds

desert survival

Mesquite is the Sonoran Desert smell carried by distant rain, omnipresent and humble, a survivor with tap root extending 190 feet down to draw on the water table.

Prosopis is the scientific name for about 40 species of leguminous trees. Present in North America since the Pliocene era, mesquite wood has been dated to 1300 BC.

I found this flowering mesquite bush in Finger Rock Canyon of the Catalina Mountains outside Tucson, Arizona.

They are thought to have evolved with megafauna in the New World. The loss of North American megafauna at the end of the Pleistocene era gave way to one theory of how the Prosopis spp. were able to survive.

One theory is that the loss of the megafauna allowed Prosopis spp. to use their fruit pods to attract other organisms to spread their seeds; then, with the introduction of livestock, they were able to spread into grasslands.

The plentiful legumes that develop from these flowers are edible when cooked. The shape and color of the seeds can be understood from this empty seed pod that happens to lie near a tarantula burrow.

Our eleven-mile trek from Apache Junction ended here between Black Top Mesa and Palamino Mountain. Peralta trail winds up the ridge to right with Weaver’s Needle beyond in the setting sun.

Deep shade combined with the distant sunlit needle made for a difficult photographic capture. In fact, this picture needed significant work in Photoshop. I wore the 8 megapixel Sony F828 to capture the handheld shots of this series. A few days later I dropped the camera while riding Colorado, rendering it inoperable. This was when I acquired my Sony Alpha 700 during downtime in Phoenix. Later, the F828 was repaired at Sony and is still operable.

Stressed Mesquite

Mesquite, of the genus Prosopis, is a widespread, successful desert shrub that sometimes grows into tree form, as you see here. A mesquite tap root can extend 190 feet down to draw on the water table.

East Boulder Creek was flowing, in this season, a few feet away. Still, this mesquite is stressed, with a loss of over half of its bark. The ever-present Prickly Pear is in the middle distance. I prefer the image with the distant Weavers Needle, a neck of eroded volcanic rock, is brightened by the setting sun. To the left, the light-colored rock of Black Top Mesa is also of volcanic origin.

I am here on the Dutchman Trail between Black Top Mesa and Palamino Mountain, Superstition Wilderness, Tonto National Forest, Arizona.

Here is a gallery of post images, making comparison easier. All were taken with a handheld Sony F828. Walking without a pack make it possible for me to wear the camera.
