I found this plant growing in huge numbers both in a sunny savannah and sunnier spots under the post oaks of a Cross Timbers forest. I was curious about it’s pollinator. Here’s an excerpt from wildflower.org :
“Two petals of the flower of this species produce oils which are collected by members of the bee genus, Centris and fed to their larvae. Centris spp. are the primary pollinators of Krameria lanceolata.”
Also krameria is said to be a parasite, although I can’t find what it’s host is. Anyone know?

The North American Toad is a part of the Chordata phylum and can be distinguished by their stripe down the center of their backs and mosaic patterns (Nature Works). This photo was taken in the forest near a small pond. The temperature was 80 degree Fahrenheit and the humidity level was recorded at 52%. There was no breeze at the time of the picture.
