Phemeranthus brevifolius. Synonym: Talinum brevifolium. (Shortleaf Rockpink)
Montiaceae (Miner's Lettuce Family)
formerly Portulacaceae (Portulaca Family)

Semi-desert. Depressions in rock. Spring, summer, fall.

Phemeranthus brevifolius enjoys sandy, gravelly depressions in sandstone slabs, such as the expanse shown at left. Such areas seem to be devoid of plants, but a close inspection reveals a number of tiny species. In the gravels and sands of the top photograph at left, there are dozens of Phemeranthus brevifolius, as the close-up of one 3'x5' area shows.

Utah plant expert Stanley Welsh indicates that Phemeranthus brevifolius flowers usually are 10-12 millimeters across with some isolated populations as large as 25 mm.  Flowers pictured at left are about 25 mm; those in photographs at the top and bottom of this page are about 15 mm. 

Leaves can be cylindrical, club-shaped, or linear and their size can vary from 1/3" as shown at left to 1/6" as shown in several other photographs on this page.

As the map below indicates, this species is not found in Colorado but is found in the other Four Corners states. 

The Talinum genus is now broken into Talinum and Phemeranthus and a number of species of each genus are found in the Four Corners states as well as in other areas of the U.S.

In 1854 John Torrey named this plant Talinum brevifolium.  In 1997 Hershkovitz placed it in a genus, Phemeranthus, that Rafinesque had named in 1814.  "Phemeranthus" is from the Greek "ephemeros" ("ephemeral"), "living for a short time" and "anthos", "flower".
