Floral stem 1 – 2 dm  tall, 2 – 6 mm thick, reddish below, glabrous to subglabrous with few scattered trichomes to irregularly hirsute, with ±  5 – 9 leaves, the leaves elliptic to ovate, 8 – 17 mm long, 5 – 9 mm wide, glabrous to ciliate.

Cincinni 5 – 11-flowered, the pedicels glabrous to somewhat pubescent, the lower 6 – 22 mm long, calyx disk 4 – 7 mm wide, the segments slightly ascending, unequal or nearly equal, elliptic to triangular-ovate, acute, 5 – 10 mm long, 2.5 – 8 mm wide, 1.5 – 3 mm thick, glabrous to ciliate, corolla 11 – 13 mm long, 6 – 9 mm thick, 5 – 6 mm wide at apex, the segments connate 1.5 – 3 mm, oblong, broadly acute, apiculate, 3.5 – 6 mm wide, glabrous or with few scattered tiny hairs mostly on or near keel and on exposed margin.

Vegetatively, the glabrous clones of this variety seem unrelated to E. setosa, but the flowers are almost identical.
