Scientists identify new plant species endemic to Lanka
By Ifham Nizam
Sri Lankan scientists have discovered a new species of Nelu, Strobilanthes medahinnensis (Acanthaceae) based on morphological and molecular data, from the Peak Wilderness Nature Reserve.
The species named “Strobilanthus medahinnensis Nilanthi”.
The research team includes Nilanthi Rajapaksa, Nuwan Jayawardena of the Department of Wildlife Conservation, Prof. Cyril Wijesundera of the Institute of Fundamental Studies, Kandy, Prof. Pradeepa Bandaranaike of the University of Peradeniya and Hiruna Samarakoon.
Nearly 450 species of Nelu spread around the world, most of which are found in tropical and subtropical Asia. With the discovery of the new species, there are about 33 species of Strobilanthus found in the natural environment in Sri Lanka, of which 27 species are endemic to Sri Lanka. Fourteen of these species are protected by the Fauna and Flora Protection Ordinance (FFPO).
Lead Scientist, Nilanthi Rajapakse, first observed several of this species in September 2015 in the Medahinna area of the Peak Wilderness Nature Reserve.
Subsequently, the research team found that the height of the reserve ranged from about 1400 m to 1500 m. This new species bears a striking resemblance to the Strobilanthus anceps Nees. The flowers of both species are white, the leaves are oval, the tips of the inflorescences are bent backwards to protect the inflorescence, and the yellow glands are located on the underside of the leaves.
Chloroplasts used as DNA barcoding to distinguish the new plant species from the other closest plant species, S. anceps. Furthermore, it explains how these two plant species separated into two species 0.33 million years ago.
The team told The Island Nelu has medicinal value for many ailments. Allowing the growth of other flowering plants in the forest due to the death of flowering plants from time to time plays an important ecologically role. It also helps maintain soil moisture. Young plucked plants are a delicacy of deer. Many birds and bees come to drink the nectar of the harvested flowers. Nelu is the host plant of some butterfly species.
The species has the ability to be used as a mature woody twig. Dyes such as indigo, are produced from the leaf extract of most harvested species. Land use for economic crops, illegal use of land, deforestation due to development projects, invasive plant growth, collection for firewood, arson, and climate change threaten plants. Due to these reasons, about 21 species of Nelu that are endemic to Sri Lanka are threatened with extinction.
Although the population was not flowering at that time, this appeared distinct in leaf characters of its morphologically closest ally S. anceps Nees (1837: 312). “We conducted extensive plant explorations across the entire distribution range of Strobilanthes in Sri Lanka covering 21 administrative districts from January 2012 to September 2020. However, this new plant was not found in any other location except Medahinna and we visited Medahinna several times to study this population since 2015. Finally, on 29th June 2020, we could observe flowers in the population at Medahinna,” the team pointed out.
After a closer examination of the specimens and critical study of the literature, comparison of the specimens at National Herbarium, Royal Botanic Gardens, Peradeniya (PDA), and online herbaria. “We found that it is different from all known species of Strobilanthes in the world. In addition to the preparations of distribution map, superlative photographs, and meticulously illustrated line drawings, the complete chloroplast genomes of this interesting material and S. anceps were also analysed. According to morphological and molecular evidence, it could not be assigned to any previously published species; hence it is described as a new species,” the team added.
The team thanked the Director General, Department of Wildlife Conservation, Sri Lanka (DWC) for the constant encouragement and facilities provided. They also thanked and Department of Forest Conservation, for permitting those to collect samples and the Agriculture Biotechnology Center, the University of Peradeniya for molecular analysis and the National Herbarium (PDA), the Royal Botanic Gardens, Peradeniya for the assistance in specimen examination, to Rukmal Ratnayake for the line drawings and acknowledged the Ecosystem Conservation and Management Project (EACAMP) for financial support.

Health authorities on high alert over Nipah Virus threat
Sri Lanka has stepped up efforts to detect and respond to a potential outbreak of the deadly Nipah virus (NiV), with health authorities enhancing surveillance and laboratory readiness amid growing concerns in the region.
The Medical Research Institute (MRI), the country’s premier laboratory, has upgraded its testing capacity with the latest technology to identify the Nipah virus, enabling early detection of suspected cases, an MRI source said.
Nipah virus is a highly infectious zoonotic disease that can spread from animals
to humans and also through human-to-human contact. Fruit bats are the natural hosts of the virus.
First identified in Malaysia in 1988, the virus has since caused deadly outbreaks in countries including India and Bangladesh. Experts warn that Sri Lanka, with its close human-animal interactions and tropical climate, must remain vigilant against such emerging infectious diseases.
The case fatality rate of Nipah virus ranges from 40% to 75%, making it one of the most lethal viral infections affecting humans. There are currently no specific drugs or vaccines, with treatment relying mainly on intensive supportive care, health specialists say.
Symptoms of infection initially include fever, headaches, muscle pain, vomiting, and sore throat, followed by dizziness, drowsiness, altered consciousness, and neurological signs indicating acute encephalitis. Severe cases may progress to atypical pneumonia, acute respiratory distress, seizures, and coma within 24 to 48 hours.Authorities continue to urge heightened awareness and precautionary measures, emphasizing that early detection and rapid response are key to preventing outbreaks.

Free Media Movement demands govt. accountability on free speech issues
The Free Media Movement (FMM) has demanded government accountability on many freedom of expression issues referred to in a statement issued by the Human Rights Commission in a statement issued last week.
The statement under the hands of FMM Convener Lasantha De Silva and Secretary Dileesha Abeysundera says FMM has paid close attention to the statement issued by the Human Rights Commission (HRC) under reference number HRC/S/i/E/03/02/26. It has also informed that global stakeholders, including the International Federation of Journalists—of which it is a member—that are already closely monitoring this matter.
In its statement, HRC has elaborated at length on the issues that have arisen in Sri Lanka concerning freedom of expression and online safety. It specifically points out that the actions of the Sri Lanka Police have been a major contributing factor to these concerns. The Commission notes that recent conduct of the police has indirectly interfered even with the professional activities of journalists.
HRC has also drawn attention to the practice of summoning journalists and other activists before the police without providing clear reasons, in violation of circulars issued by the IGP. In certain instances, the police have stated that journalists were summoned due to alleged defamation arising from media activities.
However, freedom of expression guaranteed by the Constitution is restricted only within constitutionally prescribed limits. Accordingly, defamation that is no longer a criminal offence cannot be acted upon by the police. Such matters constitute civil offences that must be resolved before courts of law. The Commission further observes that attempts by politicians and others to lodge complaints with the Criminal Investigation Department regarding defamation are efforts to portray defamation as a criminal offence.
The HRC statement also addresses the Online Safety Act. While emphasizing the need to be mindful of online safety, the Commission points out that the current law does not address genuine needs. Therefore, as already demanded by many stakeholders, the government has the option to repeal this Act.
In addition, HRC has outlined a three-pronged approach that should be adopted to safeguard freedom of expression, as guaranteed by the Constitution and in line with Sri Lanka’s commitments under the Universal Declaration of Human Rights of the United Nations.
FMM said it is of the view that the Government of Sri Lanka must give serious consideration to this statement and to the recommendations emphasized therein. “This is a moment in which the accountability of the Sri Lankan government is being questioned. Accordingly, the Free Media Movement urges the government to take immediate steps to implement the recommendations set out in this statement,” it said.

Opposition alleges Govt deliberately delaying PC polls
ITAK Batticaloa District MP Shanakiyan Rasamanickam accused the government in Parliament on Friday of deliberately delaying Provincial Council elections, pointing to its failure to nominate members to a Parliamentary Select Committee.
The committee, tasked with considering matters related to Provincial Council polls, was announced on 6 January 2026. Opposition parties submitted their nominees promptly.
However, a month later, the government has yet to name its eight members, preventing the committee from being constituted and from commencing its work, Rasamanickam alleged.
Opposition representatives argue that this delay represents intentional inaction aimed at postponing elections. They urged the government to appoint its nominees without further delay to allow the committee to proceed.
