Holoptelea integrifolia, known locally as Goda Kirilla (ගොඩ කිරිල්ල), is a large deciduous tree native to the Indian subcontinent and Sri Lanka. Recognised by its distinctive bark and broad canopy, it is a familiar presence in the island's monsoon forests and dry-zone landscapes. Despite being less celebrated than Sri Lanka's more iconic flora, this tree carries considerable ecological and ethnobotanical significance.
How do you identify Holoptelea integrifolia?
Holoptelea integrifolia typically grows to between 15 and 25 metres in height, occasionally reaching 30 metres. It develops a broad, spreading crown supported by several ascending branches, making it a prominent canopy species wherever it occurs.
The bark is one of the tree's most distinguishing features: grey to whitish-green in colour, it carries a notably offensive smell and is covered with small blisters. On mature trees, the outer bark peels away in corky scales, leaving a characteristically rough and flaky surface.
- Leaves: Alternately arranged, elliptic-ovate in shape, measuring 8–13 cm long and 3–6.5 cm wide. The surface is smooth, margins are generally entire (occasionally slightly toothed), the tip is pointed, and the base is rounded or heart-shaped.
- Fruit: A flat, winged samara notched at the top, adapted for wind dispersal.
- Seed: Flat, contained within the winged fruit.
What are the common names for this tree?
The tree goes by several names depending on the language and region:
| Language / Region | Name |
|---|---|
| Sinhala (Sri Lanka) | Goda Kirilla (ගොඩ කිරිල්ල) |
| English | Indian Elm |
| Tamil | Ayil, Velaylii |
| Other regional names | Kauchia |
The English common name, Indian Elm, reflects its resemblance to the elm family in leaf shape and fruit structure, though it belongs to the family Ulmaceae, placing it in the same broader grouping as true elms.
Where does Holoptelea integrifolia grow in Sri Lanka?
In Sri Lanka, Goda Kirilla is primarily a monsoon forest species. It favours the canopy layer of dry and intermediate zone forests, where seasonal rainfall patterns shape the vegetation structure. The tree is deciduous, shedding its leaves during the dry season — a strategy common among canopy trees in these environments.
The species is also encountered in scrubland margins, along river valleys, and occasionally in degraded forest patches across the dry lowlands. Protected areas such as Wilpattu National Park support the kind of dry monsoon forest habitat where this species naturally occurs alongside other indigenous dry-zone trees.
Beyond Sri Lanka, the species ranges across peninsular India, Nepal, and parts of Southeast Asia, typically growing in tropical dry and moist deciduous forests up to around 1,500 metres elevation.
What is the ecological role of Holoptelea integrifolia?
As a canopy tree, Holoptelea integrifolia plays a structural role in the forests it inhabits. Its broad crown provides shade that moderates understorey conditions, and its seasonal leaf fall contributes organic matter to forest soils. The winged fruits are designed for wind dispersal, allowing the species to colonise clearings and forest edges relatively efficiently.
The tree also provides habitat for a range of insects, birds, and other wildlife. In Sri Lanka's dry-zone forests, canopy trees of this scale are important for maintaining biodiversity in ecosystems that face increasing pressure from agricultural expansion and climate variability.
Trees like Goda Kirilla are ecologically complementary to other native species in Sri Lankan dry-zone forests, including Acacia chundra and Pongamia pinnata, which together form the structural backbone of monsoon woodland communities.
What are the traditional and medicinal uses of Holoptelea integrifolia?
Holoptelea integrifolia has a well-documented history in Ayurvedic and traditional medicine across South Asia. Various parts of the tree — bark, leaves, seeds, and fruit — have been used in formulations addressing a range of conditions.
- Bark: Used in traditional preparations for skin disorders, including ringworm, eczema, and other inflammatory conditions. Bark extracts have also been applied to wounds and ulcers.
- Seeds and seed oil: The seeds yield an oil that has been used topically for skin diseases and as an anti-inflammatory agent.
- Leaves: Applied as a poultice in some traditions for joint pain and rheumatic conditions.
- Fruit: Explored in traditional formulations for digestive complaints.
Modern phytochemical research has investigated the species for anti-inflammatory, antimicrobial, and antifungal properties, lending some scientific context to its traditional applications. However, any medicinal use should be guided by qualified practitioners of Ayurvedic or traditional medicine.
How does Holoptelea integrifolia compare to related species?
Holoptelea integrifolia is the only species in its genus, making it botanically distinctive. It is placed within the family Ulmaceae alongside elms (Ulmus spp.) and hackberries (Celtis spp.), but its characteristic blister-covered bark, offensive bark odour, and geographic range set it apart clearly from those related genera.
In Sri Lanka's forest context, it is sometimes encountered alongside other large dry-zone trees but is identifiable by the combination of its peeling, blistered bark, smooth elliptic leaves with a heart-shaped or rounded base, and flat winged samaras. Few other Sri Lankan trees share this precise combination of features.
Is Holoptelea integrifolia of conservation concern?
The species is not currently considered globally threatened, and it remains relatively widespread across its South Asian range. In Sri Lanka, however, the dry-zone forests that support this and many other native tree species face ongoing pressure from land conversion, firewood collection, and changing rainfall patterns linked to climate variability.
Conservation of intact monsoon forest habitat is therefore important not only for Holoptelea integrifolia but for the broader community of plants, animals, and insects that depend on these ecosystems. Sri Lanka's network of protected forests and national parks provides the most secure refuge for wild populations of the species.
