Rhus chinensis, the Chinese sumac[2] or nutgall tree, is a deciduous shrub or small tree in the genus Rhus. Growing to 6 m (20 ft) tall, it has downy shoots and leaves comprising several leaflets. These turn red in autumn before falling.[3]
The plant is common in East and South Asia,[4] and is cultivated as an ornamental in temperate climates.
Galls produced on the species that are called Chinese gall (Galla chinensis), are a source of gallotannins,[5][6] molecules of hydrolyzable tannins. Infestation of the tree by Chinese sumac aphids (Melaphis chinensis Bell) may lead to production of a gall that is valued as a commercial product in China.
Chinese galls are used in traditional Chinese medicine for coughs, diarrhea, night sweats, dysentery, and intestinal and uterine bleeding.[7] Some research has suggested that chemical compounds found in Rhus chinensis possess in vitro antiviral, antibacterial, anticancer, hepatoprotective, antidiarrheal, and antioxidant activities.[4] However, this evidence is not substantiated by multiple international researchers. The aqueous extracts of the gall also inhibit alpha-glucosidase activity in vitro.[8]

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.
