Description
This is a low-lying perennial with a woody caudex spreading to about 40 centimeters in maximum width. It forms a patch of round, paddle-shaped, woolly, gray-green leaves one to twenty centimeters wide in rocky areas. Its inflorescence is rarely erect, instead drooping or extending parallel to the ground, rarely higher than 15 centimeters.
At the end of each prostrate stem is a puffy, woolly, rounded cluster of flowers. Each flower is less than a centimeter wide, petals united in a 5-fold cup, and may be cream to yellowish or pink with red stripes. On level ground the flowerheads surround the cluster of basal leaves; on a hillside they all droop downhill.
Taxonomy
Eriogonum lobbii was scientifically described and named in 1870 by Asa Gray and John Torrey. It is classified in the Eriogonum genus as part of the Polygonaceae family. The species has one heterotypic synonym, Eriogonum lobbii var. minus, published by Gray and Torrey soon after the species publication.[2]
