     The Eriogonum genus was named by Andre Michaux (1746-1803) in his 1803, Flora Boreali-Americana.  "Erio" is Greek for "wool" and "gono" for "knee", referring, according to William A. Weber, to the "wooly leaves and swollen joints of the type species".

Eriogonum cernuum is a delicate, many-flowered plant of open sandy grasslands, shrublands, and lower altitude forests.  Though it can be abundant in certain habitats, it is so slim and has such minute flowers that it is often overlooked.  It typically grows to about ten inches tall (as pictured here) but can be nearly twenty inches tall. 

Stem leaves are usually lacking and the round, very hairy, basal leaves may be green and present, dried, or absent at flowering time.  Be sure to take a look at the leaves with a hand lens.  

When you find one plant, be sure to stop and search for more.  Almost always you will find many other Eriogonum cernuum plants in the area.

In 1834 "On the plains of the Oregon and in the Rocky Mountains", Thomas Nuttall was the first to collect this plant for science.  He named and described the plant in 1848.  "Cernu" is Latin for "nodding".

Eriogonum cernuum ages to subtle maroons.  Notice also that the basal leaves are dried and curled, in contrast to the leaves shown in the top photograph.

, it colors the land with a maroon tinge, as it did in the open meadows along the Murphy Trail where this picture was taken.

It is easy to spot the numerous Eriogonum cernuum plants in this photograph, but in the field it is actually quite difficult to see them as they are so slender and blend with the soils so well.  You can see the difficulty if you look at the plants in front of the black micro-biotic soil crust at the very top of the photograph.
