Thunbergia is a genus of flowering plants in the family Acanthaceae. It includes 150 species native to tropical and subtropical regions of sub-Saharan Africa, Madagascar, southern Asia, New Guinea, and Australia.[2] Thunbergia species are vigorous annual or perennial vines and shrubs growing to 2–8 m tall. The generic name honours the Swedish naturalist Carl Peter Thunberg (1743-1828).
Its members are known by various names, including thunbergias and clockvine. Thunbergia on its own usually refers to Thunbergia grandiflora, while Thunbergia alata is often known as black-eyed Susan vine or just black-eyed Susan (not to be confused with other flowers called black-eyed Susan). Orange clockvine is the name of Thunbergia gregorii.
Thunbergias are frequent garden escapes, becoming invasive species; T. grandiflora, T. fragrans, and T. laurifolia are considered weeds in Australia.[3]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
