Leaves of fertile stems 9-30 (-55) x 1-3.5 (-5) mm, linear to linear-oblong, acute or subacute, attenuate, mostly alternate or lowermost 3-verticillate; leaves of sterile stems up to 4 mm broad, linear to narrowly elliptic, subacute to obtuse, 3-or 4-verticillate. Inflorescence with 6-25 flowers, dense in flower, somewhat less dense in fruit. Bracts 4-8 mm, linear-oblanceolate to obovate, acute to obtuse. Pedicels 3.5-6 mm in flower and fruit, erect, free. Calyx-lobes subequal, 4.5-7.5 x 0.8-1.3 (-1.6) mm, oblong-lanceolate, subacute to obtuse, the margin scarious especially towards base, often tinged with purple. Corolla 23-32 mm, white, whitish-yellow or tinged with purple, the palate orange, the spur usually purple; adaxial lip sinus 4-7 mm; abaxial lip sinus 0.8-1.5 mm; spur 12-16 mm, straight or somewhat curved, more or less equalling rest of corolla. Style bifid. Capsule 4-5 x 3-4 mm, oblong, glabrous; loculi usually conspicuously unequal, the adaxial loculus exceeding abaxial, usually dehiscing by 5 teeth, the abaxial loculus dehiscing by 3 teeth. Seeds 0.55-0.7 mm, reniform to pyriform, strongly transversely ridged, blackish-grey; transverse ridges 4-7, discrete or rarely anastomosed, obtuse or rounded; periclinal wall of testa-cells rugulate, the margins not or scarcely raised except for rounded papilla towards ridge-apex, the median papilla absent.
