    There are nearly a dozen Physarias (Bladderpods) in the Four Corners area; Physaria acutifolia is the most common. The genus was named by Asa Gray in 1848 and is now greatly expanded with the addition of all former members of the Lesquerella genus. "Physaria" is Greek for "bladder".

Often recumbent, often reminiscent of a lawn weed gone beautiful with lovely yellow flowers, Physaria rectipes is a fine find.  A thick basal rosette of leaves gives rise to long stems with few narrow leaves, and at the top of these stems dainty bright yellow flowers cluster in a glow.

The Lesquerella genus was named in 1888 by Sereno Watson for the naturalist, explorer, and paleobotanist Leo Lesquereux (pronounced "le crew").  (More biographical information about Lesquereux.) 

Lesquerella is now part of the Physaria genus as a result of research published in 2002 by Ishan Al-Shehbaz and Steve O'Kane. ""Rectipes" is Latin for "straight foot" probably referring to the long, straight stems.

As is evident from several photographs on this page (especially the second one at left), fruits leaves, stems, and other plant parts appear gray-green. They appear so because they are heavily covered with hairs  --  almost always, as is true for other Physaria, stellate hairs, i.e., hairs that branch out in a starburst formation. See the last photographs on the Physaria acutifolia page.
