Ventilago ecorollata is a species of plant in the family Rhamnaceae native to eastern Queensland, Australia.
Ventilago ecorollata is a vine with a stem reaching up to 8 cm (3.1 in) diameter. The leaves are simple and arranged alternately on the twigs, and they have small crenulations on the leaf edges. They measure up to 6.5 cm (2.6 in) long and 3 cm (1.2 in) wide, and are held on a very short petiole (leaf stem). Stipules are hairy and about 2 mm (0.08 in) long. [4] [5]
Flowers are borne on racemes that emerge from the leaf axils . The calyx tube, or hypanthium, is about 2 mm (0.08 in) wide and has five lobes, each about 1.5 mm (0.06 in) long. There are no petals. The fruits are samaras with a single wing attached at the apex.
It was originally described and named by Ferdinand von Mueller in 1875, placing it in the genus Berchemia . The specimen he worked from was collected by John Dallachy from 'Rockingham's Bay' (now Rockingham Bay), but there were no fruits in the collection. [6] In 1880, after examining new material with fruit, Mueller moved the species to the current genus Ventilago. [5]
This species is listed as least concern under the Queensland Government's Nature Conservation Act. [1] As of 5 December 2025 [update] , it has not been assessed by the International Union for Conservation of Nature (IUCN).
