    • 1a.Flowers borne solitary in the axils of the leaves, 2 per node; leaves sessile or nearly so (petioles not longer than 4 mm) 2

    • 1b.Flowers borne in axillary or terminal racemes; leaves distinctly petiolate, the petioles longer than 4 mm 3

    • 2a. Leaf margins toothed; corollas 15–20 (–23) mm long S. galericulata

    • 2b.Leaf margins entire; corollas 6–11 mm long S. parvula

    • 3a. Stems glabrous or sparsely pubescent with short, downward-curved hairs; racemes mostly axillary; corollas straight, 6–9 mm long S. lateriflora

    • 3b.Stems densely pubescent with spreading glandular and/or eglandular hairs; racemes mostly terminal; corollas bent upward above the calyx and strongly curved, 12–23 mm long S. ovata

The generic and common names come from the small protuberance on the calyx, a feature not seen in any of our other mints
- leaves opposite

- inflorescences terminal and/or axillary

- corolla blue, bilaterally symmetrical, upper lip well developed

- style inserted deep into the base of the 4 lobes of the ovary

- calyx of essentially 2 obtuse lips with a protuberance or "little shield" across the top ("tractor seat")
