Math Photo Challenge: Week 1 of Ag, Botanical, Geological participation

We love math and we love the natural world. What better way to celebrate both than through participation in this year's Math Photo Challenge?

#MathPhoto19 #five

This is our entry for Week 1: Five. It's a Desert Five Spot (Jepson), photographed near our land in Joshua Tree National Park.

I simply admire them for their beauty, delicacy, improbable environment, vigor, and design.

My son wants to know, "Why does it have curved lines on [the petals]?"

Asked this question, my husband tells us these striations are nectar guides for pollinators.  I immediately want to return with a black (ultraviolet) light. Assuming they remain open at night...

Alas, these beauties were photographed on 20190325.

Looking forward to posting more in this challenge! (challenge website)
