Sedum stenopetalum, also known as wormleaf stonecrop or narrow-petaled stonecrop, is a species of flowering plant in the stonecrop family. It is native to western North America from British Columbia and Alberta to northern California to Wyoming. It can be found in many types of rocky habitat, such as cliffs, talus, and steep ridges.[2] It is a succulent plant producing mats or clumps of lance-shaped, linear, or three-lobed leaves each under 2 centimeters long. The inflorescence is a short, erect array of one to many flowers with lance-shaped petals up to a centimeter long. The petals are yellow, sometimes with red veins.
Taxonomy
[edit]Sedum stenopetalum is classified in the Sedum genus in the family Crassulaceae. It was scientifically described and named by Frederick Traugott Pursh in 1813.[1]
Subspecies and varieties
[edit]The species has two accepted subspecies and one accepted variety.[1]
Sedum stenopetalum subsp. ciliosum
[edit]Subspecies ciliosum was first described by Thomas Jefferson Howell as a species named Sedum ciliosum in 1898. It was reclassified as a subspecies by Robert Theodore Clausen in 1948. It only grows in the state of Oregon.[3]
Sedum stenopetalum var. monanthum
[edit]Variety monanthum was initially described as a species in 1898 by Thomas Howell, but with the illegitimate name Sedum uniflorum. It was then described by Wilhelm Nikolaus Suksdorf in 1927, again as a species, but this time with the name Sedum monanthum. It was reclassified as a variety of Sedum stenopetalum under its present name by Hideaki Ohba in 2007.[4]
Sedum stenopetalum subsp. stenopetalum
[edit]The autonymic subspecies grows in western Canada and the northwestern United States.[5]
