Description

"Annual or perennial herbs. Stems erect, teret, often in clumps. Leaves opposite, entire, sessile to short-petiolate. Flowers solitary or in congested cymes, pedicellate or sessile. Calyx 4-5 lobed, tubular; corolla cleft ½ or less its length, campanulate, funnelform or tubular, lobes the same number as the sepals, often connected with a thin tissue (pleats); stamens 4-5, anthers free, or coherent in a ring around the style; stigmas erect, recurved in age, style short or absent. Capsule laterally compressed, elongate, stipitate; seeds 0.6-2.2 mm long." [1]

"Perennial with thick fleshy roots. Stem strict, ascending to erect, 1.5-5 dm tall. Leaves elliptic, 4-8.5 cm long, 1-3 cm wide, acute to obtuse, base attenuate to cuneate, sessile to short-petiolate. Flowers essentially sessile, solitary or in compact, 3-7 flowered cymes. Calyx 2-3.3 cm long, tube 7-13 mm long, lobes linear to narrowly elliptic, 10-20 mm long, to 3 mm wide, acute, erect to ascending; corolla greenish to yellowish white, usually tinted or striped with purple, funnel form, 3-4.2 cm long, tube 2.5-4 cm long, lobes 5, triangular-ovate, the corolla, anther adherent; stigmas spreading-recurved, style 3-5 mm long. Capsules ellipsoid to oblong, laterally compressed, 1.7-2.5 cm long, stipitate; seeds brown, ellipsoid to oblong, faintly reticulate, 1.1-1.3 mm long." [1]
