Asplenium

Leaves pinnate at the base, pinnatifid above; spores abortive (or normal in A. tutwilerae, known only from Hale County, AL); [V. Schaffneria clade; reticulation between two subclades].

Sporobolus

First glume glabrous, acute to acuminate; spikelets purplish (fading tan); base of plant smooth and hard, made up of the indurated leaf bases; grain oblong (when present, usually abortive); [of pine savannas and seeps of the Coastal Plain of NC south to c. FL, west to e. TX and se. OK].

Artemisia

Disk flowers functionally sterile (with abortive ovaries); corollas subglobose; fresh plants either not aromatic or with a tarragon odor; [subgenus Dracunculus].

Asplenium

Leaf blade outline tapering evenly from near or at the base, with a long-attenuated tip; spores abortive; on moist outcrops of felsic sedimentary or metamorphic rocks, such as sandstone, phyllite, schist; [inland from nc. GA and nc. AL northwards]
