1 Leaves unlobed. | |
1 Leaves pinnatifid. | |
3 Laminar scales of the upper leaf surface absent or essentially so; glands inconspicuous, on the proximal acroscopic side of the basal pinnae; rhizome scale margins strongly erose-serrate; laminar scales of the lower leaf surface sparse, lanceolate, sometimes touching, their margins undulate, entire; orbicular scales present and readily visible; [widespread in our area] | |
3 Laminar scales of the upper leaf surface bearing scattered scales, these subulate, the base pectinate-stellate, apex long caudate, margin weakly erose; glands conspicuous, round to elliptic, rather swollen with a central depression, on a small auricle within the sinus near the acroscopic side of the basal pinnae; rhizome scale margins erose-ciliate; laminar scales of the lower leaf surface dense, lanceolate, their margins ciliate (peripheral scales often extending beyond the margin of the blade); orbicular scales present, but not readily visible; [FL Keys only] |

3 Leaf blade scaleless on the lower surface; [subfamily Campuloneuroideae] | |
4 Stems (rhizomes) short-creeping, 2-10 mm in diameter, the leaves clustered; main lateral veins either readily apparent (and then parallel to one another or obscure | |
5 Leaves palmately lobed, the lobes branching dichotomously; foliage indument of stellate hairs; [subfamily Platycerioideae] | |
