Listing Status: Endangered

Where Listed: WHEREVER FOUND

General Information

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.

» Life History

Habitat Requirements

Stenogyne campanulata grows on the rock face of a nearly vertical, north-facing cliff in diverse lowland or montane mesic forest at elevations from 335 to 1,290 m (1,100 to 4,232 ft). The associated native plant species include Lepidium serra (anaunau), Lobelia niihauensis, Lysimachia spp. (lehua makanoe), Melicope pallida (alani kuahiwi), Metrosideros polymorpha (ohia), Neraudia kauaiensis (maaloa), Nototrichium divaricatum (kului), Poa mannii, Remya montgomeryi, and Wilkesia gymnoxiphium (iliau).

Movement / Home Range

Stenogyne campanulata historically occurred in Kalalau Valley on Kauai and currently occurs in the left branch of Kalalau Valley on State-owned land in Na Pali Coast State Park.

Reproductive Strategy

Stenogyne campanulata flowers in January, May, June, and August, with fruiting in January, April, May, and June. Little else is known about the life history of this species. Its pollination vectors, seed dispersal agents, longevity, specific environmental requirements, and limiting factors are unknown.

Other

A short-lived perennial, Stenogyne campanulata is distinguished from closely related species by its large and very broadly bell-shaped calyces that nearly enclose the relatively small, straight corollas, and by small calyx teeth that are half as long as wide.
