General Information
Dubautia herbstobatae, a member of the Asteraceae (sunflower) family, is a small spreading shrub to 50 cm (20 in) tall. The shiny, leathery leaves are oppositely arranged, narrowly elliptic in outline, and 2 to 5.5 cm (0.8.to 2.2 in) long by 3 to 11 mm (0.1 to 0.4 in) wide. Leaves have one main vein and smooth or nearly smooth margins. There are 5 to 10 heads in an inflorescence each composed of 4 to 20 yellowish-orange, tubular florets, 3 to 5 mm (0.1 to 0.2 in) long. The fruit is a seed with a dry, unopening wall (an achene) covered with silky gray hair.» Range Information

» Life History
Habitat Requirements
Dubautia herbstobatae occurs on rock outcrops on north-facing ridges in dry to mesic shrubland at 580 to 910 m (1,900 to 3,000 ft). Associated native species include Metrosideros spp. (ohia) and Eragrostis variabilis (kawelu).
Movement / Home Range
Dubautia herbstobatae occurs in the northern Waianae mountains on Ohikilolo and Kamaileunu ridges.
Reproductive Strategy
Dubautia herbstobatae is likely out-crossing and possibly self-incompatible (i.e., pollen from the same plant will not produce seed). Flowering usually occurs in May and June. Pollination is almost certainly achieved by insect activity, and fruit dispersal is probably quite localized.
Other
Only two species of Dubautia on Oahu have the outer bracts of the flower heads fused, forming a cup surrounding the florets: of those two species, D herbstobatae has one large vein showing in each leaf, while the other species has 5 to 11 veins.
