Description
Shape, trunk, and bark
Evergreen trees with cylindrical, straight boles, growing up to 40 m tall, occasionally up to 60 m.[4] In evergreen forests, the trees can grow to large girth, with an individual reaching up to 5.26 m in girth recorded in Kodagu.[5] The bark is smooth, grey with green and white blotches on the trunk[6] and a cream colored blaze.[4] On scarring, it exudes a white, aromatic resin. The tree has dense foliage in a oval or dome-like canopy. The young branchlets are nearly cylindrical and have stellate (star-shaped) hairs.
Leaves
The leaves, which are simple, alternate, and arranged in a spiral around the twigs, are leathery, about 8-27 x 4.5-10 cm in size, glabrous, elliptic-oblong, with a short pointed tip, rounded base, and entire margin.[4] The young leaf flush is a dark red or maroon, turning to pinkish red and green as the leaf matures. The petioles are 2 to 3.5 cm long, swollen at apex, and nearly glabrous, with narrow lateral stipules that fall off. The venation of the leaves comprises 13 to 20 pairs of secondary nerves, with closely parallel tertiary nerves at right angles to the secondaries.
Flower, fruit and seed
The inflorescence appears in axillary panicles densely clothed in stellate hairs. The flowers are white, fragrant, about 2 cm across, with 5 petals, about 40-50 stamens and yellow anthers,[7] with a columnar style that protrudes beyond the anthers.[8] The fruit is a 3-valved capsule, brown, and oblong or egg-shaped, about 6.4 x 3.8 cm in size. The base of the fruit has the persistent remains of the calyx with the 5 sepals curved back. The ovary is 3-celled, with 2 ovules in each cell,[9] but the fruit typically produces a single seed with large cotyledons.[4]
Taxonomy
Vateria malabarica Blume is a Synonym of Vateria indica L. The genus Vateria has three species with accepted names,[10] of which Vateria indica and Vateria macrocarpa occur in India and Vateria copallifera occurs in Sri Lanka. Vateria indica has smaller leaves (7-20 x 5–9 cm), shorter petiole (25–40 mm), and oblong fruit compared to Vateria macrocarpa that has larger leaves (14-40 x 6–20 cm), longer petiole (25–60 mm), and ovoid or oblong fruit with pointed, often curved tip.[7]
Studies indicate the species has a mitotic chromosome number of 2n=22.[11] Polymorphic microsatellite markers have been identified for Vateria indica and the species has an expected heterozygosity of 0.44 to 0.84.[12]

Distribution and habitat
The species is endemic to the Western Ghats mountain range in India, in the southern and central region, from the Agasthyamalai Hills in the south to southern Maharashtra. It chiefly occurs in the states of Kerala, Tamil Nadu, and Karnataka.[3] The species occurs in evergreen forests from the coastal plains and foothills usually up to an elevation of about 760 m,[5] or to 800 m on the windward side of the Western Ghats in Karnataka.[6] Although it is more common in lower elevations, trees may be found up to an elevation of 1200 m.[5]
Outside forests, the tree is found as avenue trees along roadsides in some areas. In Karnataka, the species does not occur in Uttara Kannada district, but was introduced by the Sonda Kinds about 500 years ago and planted along the roadsides in Sirsi, Siddapur, and Yellapur towns.[6] It was planted extensively as an avenue tree in Dakshina Kannada and the Malabar and Travancore regions of Kerala.[5]
Climatic factors
Within its distributional range, Vateria indica occurs in areas with a mean annual rainfall of 2000 to 3000 mm and a mean annual temperature slightly over 27°C (range 16.7°C to 37.8°C). The number of rainy days varies from 118 to 130 with a mean annual humidity of 77-79% within the zone of distribution.[5]
Geology, soil, and topography
Vateria indica occurs in areas where the underlying rock is a gneissic complex, often laminated, which may be covered by laterite 9-10 m deep. The laterite may be in stages of disintegration from hard rock to fine gravel. Typically the trees occur in forests with a thick layer of humus on the surface. The trees are also found in lowland and plateau locations, but mostly occur along well-drained river banks and valleys in humid, moist forest tracts.[5] Valleys with deep sandy soil and high water table support Vateria indica dominated forests at lower elevations.[14] The trees also occur in Myristica swamp forests in Kerala[15] and Karnataka.[16]
Ecology
Vateria indica is bee-pollinated.[8]
In Myristica swamp forests in Kerala, they occur with other trees such as Myristica fatua var. magnifica and Syzygium travancoricum, understorey vegetation including Ochlandra bamboos, Pandanus screw pines, and species of aroids, Acanthaceae, and gingers.[15] In Myristica swamps of Karnataka, Vateria indica occurs in forests dominated by trees such as Gymnacranthera farquhariana, Myristica fatua var. magnifica, Mastixia arborea, the dipterocarp Hopea ponga, and the palm Pinanga dicksonii.[16]
Uses
Vateria indica wood has been used for making tea-chests, partitions, packing and cordite cases, coffins, boxes, planking, posts, floorings, ceilings, and cabinets, besides bobbins and shuttles in the textile industry, oars for sea-going vessels, and match-splints[3][9] Large amounts of Vateria indica timber were shipped from the Malabar region to Bombay to be sold as “Malabar White Pine” (Vellapiney),[9] with around 6200 tons of timber used per annum in the late 1960's.[17] The wood, after preservative treatment, was also used for railway sleepers.[9]
Resin of Vateria indica, extracted by scratching the tree's bark, is called white dammar, also known as “Malabar fallow”, “dhupa fat”, “Indian Copal”, or “piney resin”. It is used as incense in India, for incense sticks,[18] and to manufacture candles and soaps.[3] From dried kernels, a fat called “piney tallow” was extracted, which was used to adulterate ghee, making candles and soaps, to treat chronic rheumatism, and for sizing cotton yarn in place of animal tallow.[9] The resin mixed with coconut oil makes an excellent varnish resembling copal.[9] The bark, resin, and leaves are used in Ayurvedic, Siddha, Unani, and folk medicine[3][19][17] for the treatment of leprosy, eczema, rheumatism, diarrhoea, and ulcers.[19] Fine shavings of resin are administered internally to check diarrhoea.[9] Vateria indica oil, produced from the seeds, is refined to yield a fat used in confectionery and cosmetics.
Experimental assays
The bark extract may have potential for treatment of degenerative brain conditions. One study found that young amnesic mice subjected to pre-treatment with ethanol extract of Vateria indica bark gained neuro-protection and enhanced memory.[20] Several stilbenoids (bergenin, hopeaphenol, vaticanol B, vaticanol C, and ε‐viniferin) found in resins (ethanol extract from stem bark of Vateria indica) have been shown to have some in vitro anticancer activity against mouse sarcoma 180 cells by retarding tumor growth when administered in high doses (30 or 100 mg/kg body mass).[21] Experiments on rats also indicate significant reduction of obesity after administration of aqueous extract of stem bark.[22]
Chemical constituents
Stem bark
From the stem bark of Vateria indica, two novel stilbenoids, vateriaphenols A and B, have been isolated along with ten known stilbenoids and bergenin.[23] The stem bark also contains high phenol and flavonoid content. In one study, the stem bark yielded 670 mg/g and 310 mg/g total phenolic content in ethanolic and aqueous extracts, respectively, while the corresponding total flavonoid content was 74 mg/g and 62 mg/g.[24]
Leaves
The leaves have yielded two new resveratrol (5E24hydroxyphenylethenylbenzene1,3diol) derivatives, vateriaphenols D and E, along with six known resveratrol oligomers, a isocoumarin bergenin, and a benzophenone.[25] Another study isolated from the leaves a number of compounds: a novel resveratrol dimeric dimer having a C2-symmetric structure (vateriaphenol F), two new O-glucosides of resveratrol oligomers, vateriosides A (resveratrol dimer), vateriosides B (resveratrol tetramer), besides a new natural compound, and 33 known compounds including 26 resveratrol derivatives.[26]
Seeds
Vateria indica seeds have nearly 19% oil / fat content, with poly-saturated fatty acids like oleic acid (48%) and stearic acid (43%),[27] which has potential for conversion to biodiesel.[28] Optimal oil yield of 22.85% has been noted using the solvent extraction at a temperature of 66.6 °C, extraction time of 4.41 hour, and under a solvent to seed ratio of 1.353 ml/g.[29] Pure, white starch at about 30% yield has been isolated from defatted Vateria indica seed meals. [30]
Conservation
The species was previously listed as Critically Endangered in the IUCN Red List of Threatened Species because of over-exploitation for timber for the plywood industry, habitat loss, and other human activities.[31] A 2020 assessment has placed the species in the Vulnerable category.[32] According to the recent assessment, besides the timber exploitation and extensive habitat loss due to human activities in lowland areas, the species has very restricted seed dispersal, limiting regeneration. Market-driven and intensive harvest of the nuts in recent years is expected to further affect the remaining populations.[33]
