Kusum oil is a type of oil extracted from the seed of the Kusum tree (Schleichera oleosa). The plant, which is also commonly known as Ceylon oak, lac tree, or Macassar oiltree, [1] belongs to the family Sapindaceae. The sapindaceae family is named after J. C. Schleicher, a Swiss botanist, and the species name means "oily" [2] or "rich in
Fruit: The fruit is 2.5 to 3 cm long - roughly the size of a small plum - and ovoid, 1-3 celled, and more or less abruptly tapering to a point, dry indehiscent. Seed : The seed is 1.5 cm long, smooth, brown, and enclosed in a succulent aril which has an acidic taste, and contains 25-38% oil and up to 22% protein .
Alectryon excelsus is a sub-canopy tree growing to 9 m (30 ft) in height. It has a twisting trunk with smooth dark bark, spreading branches and pinnate leaves. [2] Adult leaflets do not have marginal teeth or usually have very few, blunt and shallow marginal teeth and usually leaflet margins are downturned, whereas, in juvenile leaflets have leaflets with strong teeth and flat along the edges.

An oak is a hardwood tree or shrub in the genus Quercus of the beech family.They have spirally arranged leaves, often with lobed edges, and a nut called an acorn, borne within a cup.
It is in the white oak section, Quercus sect. Quercus, and is also called mossycup oak, mossycup white oak, blue oak, or scrub oak. The acorns are the largest of any North American oak (thus the species name macrocarpa , from Ancient Greek μακρός makrós "large" and καρπός karpós "fruit"), and are important food for wildlife.
Oak seeds are faster-growing than many other trees and can compete very successfully. To regenerate oaks, the oak saplings should be 4–5 feet tall before removing the overstory. To favor oak regeneration, non-oak stems in the understory exceeding 4 feet can be controlled by various methods. The quality of the environment impacts oak regeneration.
In 1989, Lawrie Johnson and Alex George described subsp. miodon in the Flora of Australia, and the name, and that of the autonym are accepted by the Australian Plant Census: Casuarina cunninghamiana Miq. subsp. cunninghamiana [ 6 ] is a tree to 15–35 m (49–115 ft), the articles 6–9 mm (0.24–0.35 in) long with 8 to 10 teeth.
In home gardens, for example, the seeds of plants which are otherwise difficult to grow from seed may be made viable through scarification. The thawing and freezing of water, fire and smoke and chemical reactions in nature are what allow seeds to germinate but the process can be sped up by using the various methods described thus far.
