Identification Key
1. Leaves on aerial stems monomorphic, not in distinct ranks, axillary leaves absent at branching points (Bryodemsa or sect. Homoeophyllae or subgenus Tetragonostachys)
2
1. Leaves on aerial stems dimorphic, arranged in 4 ranks (2 median, 2 lateral), axillary leaves present at branching points
3
2. Underground (rhizomatous) stem leaves not scalelike; rhizophores mostly aerial; sporophyll base pubescent; leaf and sporophyll apices often puberulent
2. Underground (rhizomatous) stem leaves scalelike; rhizophores mostly subterranean; sporophyll base glabrous; leaf and sporophyll apices glabrous
3. Stems and branches generally stiff; megaspores tuberculate to verrucate, often interconnected, or smooth; microspores verrucate, blunt-spiny, cristate, and lamellate; non-native, escaped from cultivation (Didiclis or ser. Sarmentosae)
4
3. Stems and branches generally weak, lax; megaspores Stachygynandrum-type of more or less open and irregular meshes or few tuberculate on surface; microspores baculate, blunte spiny, verrucate, papillate, or coarse etc.; native species (Selaginella s.str.)
