Scientists identify new plant species endemic to Lanka

Published

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.

Switzerland to vote on plan to cap population at 10 million

A yes-vote poster paints the planned cap (L) as a way of protecting Switzerland, but opponents call it a "chaos initiative"[BBC]

Can a country put a fixed limit on its population? That is the question Switzerland will be answering on Sunday when voters go the polls to decide on a proposal to cap their population at 10 million, a move that has exposed divisions about immigration in the Alpine nation.

The move is backed by the right-wing Swiss People’s Party, which describes it as a “sustainability initiative” aimed at easing pressure on housing, public services and the environment. However some voters see this as the party’s latest anti-immigration move.

Dubbing it a “chaos initiative”, the government, other political parties, business leaders and trade unions argue it will deprive hospitals and hotels of much needed staff, and damage hard-won relations with the European Union, leaving non-EU member Switzerland isolated in a very risky world.

Switzerland’s population has grown rapidly since 2002, when it stood at 7.3 million. Now it is 9.1 million, 27% of whom are Swiss residents who were born abroad.

Switzerland’s system of direct democracy means all major decisions are taken via the ballot box. Campaigners simply have to gather 100,000 signatures to ensure a nationwide vote.

Many voters are concerned by overcrowded trains, expensive apartments and rising health costs.

The latest opinion polls indicate this could be a very close vote.

They suggest voters are inching towards a no vote by a wafer thin margin, with 52% opposed – but polls remain divided, with 45% saying they are in favour of the proposal and a significant number of voters still undecided.

Court orders former Atamasthanadhipathi to provide blood sample for DNA testing

Published

Anuradhapura Chief Magistrate, Siyapath Sasindu Wickramaratne, on Friday (12) ordered former Atamasthanadhipathi Pallegama Hemarathana Thera, who stands accused in a case involving the alleged serious sexual abuse of a minor girl, to provide a blood sample for DNA testing.

Accordingly, the court directed the suspect monk to appear before the Government Analyst’s Department on June 16 and provide a blood sample to the Government Analyst.

The order was issued after considering a further report submitted to court by the Nittambuwa Police.

Police informed the court that, pursuant to an earlier court order, certain case material had been forwarded to the Government Analyst on May 4, 2026, for DNA examination.

According to police, the material consisted of clothing allegedly stained with blood, which had been buried and concealed by the girl and later recovered during investigations.

Police further informed the court that the Government Analyst’s report had confirmed the presence of DNA evidence on the clothing.

Investigators told court that it was necessary to obtain a biological sample from the suspect monk in order to compare it with the DNA evidence recovered from the garments.

Police therefore requested an order compelling the suspect to provide a blood sample so that it could be determined whether the DNA evidence found on the girl’s clothing matched that of the suspect.

Having considered the submissions, the Magistrate ordered the suspect monk to provide the blood sample. The court also directed the Government Analyst to submit the report of the subsequent DNA examination.Pallegama Hemarathana Thera was previously remanded in connection with the case and was later released on stringent bail conditions.

High fuel prices spark outrage in transport sector, services halved

Published

on

(Asiatimes) From this week, those using private buses in Sri Lanka may face severe transport disruption, as operators in the sector have decided to cut services by 50%. Among the reasons for the protest are mounting losses, rising fuel costs and the government’s failure to grant fare concessions. At a press conference held on 7 June, Gemunu Wijeratne, president of the Sri Lanka Private Bus Owners’ Association, explained that “the authorities have not responded positively to requests for a review of bus fares and support measures regarding fuel”.

Meanwhile, around 25% of private transport vehicles have already voluntarily ceased operations due to financial difficulties. According to the majority of owners, “the decision comes after ongoing disputes with the authorities regarding fare adjustments and financial relief, which have not been met to date, despite numerous requests made over a long period”. Commuters, especially in Colombo and the surrounding areas, risk facing delays and overcrowding as the reduced fleet operates under the new directive.

According to Wijeratne, “the association will continue to provide a reduced service until the government approves a revised bus fare, in line with the rise in fuel prices”. The alternative for the government, he continues, is to provide “a direct subsidy to operators, as recent fuel price increases have placed considerable pressure on daily transport operators”.

During peak hours such as the morning, school finishing times and the evening rush hour, only essential services will be guaranteed. During these times, instead of four journeys, only three will be made. Overall, operations will be reduced to around 50%. “The government,” the chairman clarifies, “must take responsibility for this situation, as the majority of students and employees use private buses for their daily commutes, particularly to and from Colombo to various parts of the country.”

Operators in the sector point out that although they requested a temporary exemption to guarantee bus services for one month, neither the National Transport Commission nor the Minister of Transport responded positively. The annual fare review is due to be implemented during the first week of July, adding that they have the “legal authority” to “apply the revised fares”. On 5 June, Wijeratne continues, “we held discussions that were unsuccessful. Diesel prices are expected to rise by the end of this month. In view of all this, we are proceeding with the fare review. This year’s fare adjustment will be difficult for the public to bear, as all costs have risen by around 20–25%”.

The president of the Association of Private Bus Owners concludes by noting that “we cannot continue to operate at a loss. For this reason, we have asked the authorities for some concessions on diesel within the regulatory framework, but these measures have not been implemented. We have therefore decided to step up our industrial action. This week we will intensify our action by changing timetables and limiting operations. The decision was taken – he notes – due to the lack of a positive response to the request for a fare review following the recent rise in fuel prices”.

Recently, the Ceylon Petroleum Corporation (CPC) increased fuel prices in accordance with its monthly pricing formula. Among the changes, the price of a litre of petrol was increased by 15 rupees, rendering the current tariff structures unsustainable. To grasp the scale of the emergency and understand the impact on the population, AsiaNews spoke to Akalanka Punchihewa, Senuli Amrasekara and Dunesh Mayadunne, commuters from various parts of the country who travel to the capital every day for work. “We struggle,” they confirm, “to get to work from Kandy, Kurunegala and Galle. The recent decision by private bus operators is a severe blow, as we have to spend several hours in long queues just to get on a bus. The service provided by buses run by the Sri Lanka Transport Board (SLTB) is inferior to that of private buses. And we cannot,” the commuters conclude, “afford to travel to work by car or motorbike, as we are unable to bear the increased cost of fuel.”
