Selaginella deflexa

A small, yellow-green spikemoss endemic to Hawaii, 10–25 cm tall with downward-bending leaves. It grows among mosses in montane wet bogs and is ranked critically imperiled, so it is almost never in cultivation. The targets below describe cool, wet, cloudy bog conditions and are estimated rather than tested.
