Discussion
Kiaeria falcata is often found on horizontal rock surfaces in late-summer snowmelt areas. It grows in denser tufts than any other species of the genus. The epithet “falcata” refers to its falcate leaves, a character shared with K. starkei separating both species from K. blyttii. It is distinguished from K. starkei by its shorter, non-ribbed capsules and horizontal rather than vertical rock habitat.
