Leaves green to gray-green, linear-lanceolate to narrowly oblong, 1.5–7.5 cm, not fleshy, margins plane, involute, 0 (–3) -lobed, apex rounded; lobes spreading, linear or filiform, originating from distal 1/3 of blade, apex acute.

Calyces colored as bracts, 23–27 mm; abaxial and adaxial clefts 10–15 mm, 33–50% of calyx length, deeper than laterals, lateral 4–9 mm, 15–33% of calyx length; lobes oblong to lanceolate or narrowly triangular, apex acute to rounded. Corollas straight or slightly curved, 24–37 mm; tube 15–22 mm; slightly shorter than calyx or usually with beak, sometimes abaxial lip, exserted beyond calyx apices; beak adaxially green to yellowish, 7–15 mm; abaxial lip green or yellowish, reduced, ± inconspicuous, slightly pouched, 1.6–6 mm, less than 50% as long as beak; teeth spreading, yellow or yellow-green, 1–4 mm.
