Source-derived summary

Dipterocarpus zeylanicus, commonly known as හොර - Hora in Sinhalese and සරල - Sarala or කිරිපලු - Kiripalu, is a species of Dipterocarpus that is endemic to Sri Lanka. A closely related Indian species is Dipterocarpus turbinatus. The Sri Lankan tree is a large tree that grows up to 40–45 m (131–148 ft) tall and 4–6 m (13–20 ft) in circumference. The bark is light pinkish brown or light yellowish brown. Leaves are big and oval, 5 to 8 inches (13 to 20 cm) long. The sharp-edged leaves are covered with silver hairs. Flowers bloom in April and seeds have two wings to spread from wind. The bark contains considerable amounts of gray colour oleoresin. D. zeylanicus can be found in moist low country like Ratnapura, Kaluthara, Galle and Matara Districts and also in the Sinharaja rain forest.

The tallest (nearly 60 m (200 ft)) trees of Hora in Sri Lanka are found in Udakiruwa village in Lunugala and under great threat of legal/illegal felling.

Editorial summary

The public source identifies “Dipterocarpus zeylanicus” as species of plant. This brief keeps that definition visible, then builds a research path around Dipterocarpus, zeylanicus and species.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 165-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Dipterocarpus, zeylanicus and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Dipterocarpus zeylanicus”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Apr 15, 2026. The linked authority identifier is Q3025504. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
