Like yesterday’s starflower, Alaska moss heath or Alaska bellheather is found in northwestern North America and northeastern Asia. In most books, you’ll find this species listed as Cassiope stelleriana, but it does seem to more properly belong in the different genus. If you’re able to, see Stevens, P. 1970. Calluna, Cassiope and Harrimanella: A Taxonomic and Evolutionary Problem. New Phytologist. 69(4):1131-1148. Properties differentiating the two include leaf arrangement (spirally arranged in Harrimanella vs. decussate (opposite pairs) in Cassiope) and petiole length (short in Harrimanella vs. absent in Cassiope). Eight other differences between the two genera are also noted in the paper.
A low cloud ceiling was ever-present during the Alaskan portion of my trip, so these images were taken in the clouds at @1050m (3450ft) along Hatcher Pass.
