    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".

Physaria fendleri
Physaria fendleri.  Synonym: Lesquerella fendleri.  (Fendler's Bladderpod)
Brassicaceae (Mustard Family)

Semi-desert. Sandy openings, shrublands. Spring.
The Hogback, New Mexico, April 24, 2007.

This intensely golden-yellow flower occurs singly and in scattered patches brightening even the cloudiest of days -- as it did on the very cloudy and windy day I took these pictures.  This is a well-established perennial which has numerous stems with many flowers on each stem.  The blue-green cast to the stems and leaves comes from a myriad of white stellate hairs (hairs that branch in a starburst pattern) that cover a dark green cell pigment (see the last photographs on the Physaria acutifolia page).

Asa Gray named this plant Vesicaria fendleri in 1849 from a specimen collected by the highly respected Augustus Fendler near Santa Fe in 1847.  Sereno Watson named it Lesquerella fendleri in 1888.  O'Kane and Al-Shehbaz renamed it Physaria fendleri in 2002.   (More biographical information about Fendler.)
