The type specimen of Sedum obtusatum subsp. boreale View in CoL (Clausen 4952 et al.) was interpreted different ways. It was collected from Mud Creek on Mount Shasta in the southern Cascade Range, a location somewhat disjunct from other Sedum View in CoL populations. The taxon was originally described as having pale to deep yellow, somewhat spreading petals, and associated with specimens collected further west ( Clausen 1942). We interpreted at least one of the paratype specimens cited (J. T. Howell 13450 (CAS), from Siskiyou County, California, Salmon-Trinity Alps, Caribou Basin, 25 July 1937) as S. oregonense View in CoL . Later, Clausen (1975) and Denton (1982) applied the name S. obtusatum subsp. boreale View in CoL to plants of the northern Sierra Nevada that had relatively large mats of dense rosettes and wide, apically obtuse, white petals that were pink at the base and senesce pink throughout, plants that we considered to be S. paradisum subsp. subroseum View in CoL . We interpreted Clausen 4952 et al. and other plants recently collected from the canyon of the type locality (Colberg MEC-1, Cooke 15459) as belonging to S. kiersteadiae View in CoL .

Distribution and ecology: —Most populations were in the Klamath Ranges ecoregion along the border of Siskiyou County with Trinity and Shasta counties ( Fig. 25 View FIGURE 25 ). The northeastern-most colony was on Mount Shasta, in the high Cascade Range ecoregion (Jepson eFlora 2017). Sedum kiersteadiae preferred rock outcrops and rocky open forests, at elevations of 1145–2300 m. It grew on serpentine and volcanic substrates.
Notes: — Sedum kiersteadiae ( Fig. 29 View FIGURE 29 ) rosettes were relatively open, with most of the nodes well separated. The stem leaves were elliptic to obovate. The inflorescences were cylindrical. The sepals were half or less as long as the petals. The petals were yellow, often marked with red on the midrib or base, aging reddish, narrow, and acute, spreading about 90° from the flower axis at anthesis. The fresh anthers were usually rusty, dark orange, or red, senescing dark purple to black, less commonly yellow, senescing brown.
Sedum kiersteadiae was compared to the similar species S. citrinum and S. rubiginosum under S. citrinum ( Fig. 24 View FIGURE 24 ).
