Stenogyne campanulata, a member of the mint family (Lamiaceae), is a vine with four-angled, hairy stems. The hairy leaves are broadly oval, about 5 cm (2 in) long and 2.6 to 3.6 cm(1.0 to 1.4 in) wide. The flowers occur in clusters of about six per leaf axil (the upper angle formed where a petiole or branch joins a stem). The very broadly bellshaped, hairy calyces (the sepals of a flower collectively) are about 13.0 mm (0.5 in) long, with teeth that are 2.0 to 3.0 mm (0.08 to 0.12 to in) long and 5.0 to 6.0 mm (0.2 to 0.24 in) wide at the base. The petals are fused into a straight, hairy, white tube about 13.0 mm (0.5 in) long, with short purple lobes. The fruits of this species have not been seen, but the fruit of all other members of this genus are fleshy nutlets.
