A Member of the Araliaceae family of trees, Heptapleurum actinophyllum was formerly known as Schefflera actinophylla. Schefflera is an epiphyte in the genus. The tropics and subtropics are home to a large number of Schefflera species, which number over 650. The Schefflera looks a lot like an exotic, 25-foot-tall plant umbrella thanks to its huge, palmately complex, lustrous leaves perched atop its numerous, thin, naked trunks. Schefflera gives any landscape usage, from patio pots to interiorscapes to covered outdoor areas, a tropical feel. Schefflera will expand quickly to form a dense windbreak or screen for property lines and is capable of growing to a height of 40 feet. In the summer, trees that are growing in full sunlight will bloom, with an odd arrangement of tiny blooms on three-foot-diameter, rigid terminal clusters. These clusters, which are held above the foliage, are organized like the tentacles of an octopus or the ribs of an inverted umbrella. After the crimson blooms, half-inch reddish-purple fruits appear. Several Schefflera species’ leaves and bark are used as diuretics and cough remedies. The treatment of asthma, liver disorders, rheumatism, arthritis, sprains, fractures, stomach ache, antipyretic, anti-inflammatory, analgesic, migraine, and general tonic is among the ethnomedical uses of Schefflera (Ragasa et al., 2005). Caffeoyl acids, quercetin glycoside, and oleanolic acid glycoside are the primary components of S. venulosa extract, which promotes blood circulation and guards against cerebral and heart vascular disorders (Purohith et al., 1991).
Neolamarckia cadamba, also known as “Kadamba” in Ayurveda, is a member of the Rubiaceae family. A beloved plant of “Lord Gopal,” known by the Hindi name “tree Kadam,” is one of the vascular plants mentioned in ancient Sanskrit texts. Large deciduous tree with a height range of 37.5 to 45 metres. New trees have even bark and a grayish-green look. Older trees have alternate, uneven grey bark that is longitudinally fissured as part of their look. Glossy, dark green, simple pulpiness base, sub sessile to petiolate, broadly ovate to elliptical-oblong, whole, apex, and pinnate venation are all characteristics of the leaves. From August to October, orange to yellow flowers begins to bloom. Clustered inflorescences with terminal globose heads, sub sessile, and fragrant. Fruit lets plentiful with top sections that feature four voids or rigid structures.
The species is commonly, but wrongly, referred to as Anthocephalus Chinensis because it possesses fragrance orange blooms that are present in thick globe-shaped clusters and are used to make perfumes. It is a decorative plant that is also utilized in the production of paper and lumber. In Indian mythology and religion, it is of utmost importance. Given the great significance of the cadamba tree to humanity, several religions in India have fervently held that God resides within one. Ayi Jagadamba Mad Amba Kadamba Vana Priyavaasini Haasa Rate is a Sanskrit shloka that states that Goddess Durga likes to reside in a forest of Cadamba trees.

These are also known as Slime Molds because they show the holozoic mode of nutrition. these are also known as Decomposers because they show the saprophytic mode of nutrition. the slime molds were placed in kingdom fungi because some of the characters resemble fungi but due to their unicellular and eukaryotic nature, they are shifted to Protista which is why they are known as protistan fungi.
