Corolla yellow, tubular-campanulate, 5-9 mm, midpetaline bands distinctly 5-veined, purplish tinged outside, inside pubescent basally; limb slightly 5-lobed. Filaments pubescent basally. Ovary glabrous. Capsule enclosed by persistent calyx, brown-black, ± globular, 5-6 mm, longitudinally grooved, glabrous, apiculate. Seeds grayish brown, ca. 2.5 mm, glabrous. 2n = 30.

• Antioxidant / a-Amylase Inhibition / Cytotoxicity: In a study of several extracts, the methanol showed better antioxidant activity in the DPPH radical scavenging method. The methanol and hexane extracts exhibited a-amylase inhibitory activity. An ethyl acetate extract showed cytotoxicity in brine shrimp lethality.
