New species of Nelu discovered from Knuckles
By Ifham Nizam
Lead scientist on Molecular Biology and Plant Taxonomy Dr. Nilanthi Rajapakse of the Department of Wildlife Conservation and her team have discovered a new species of Nelu, Strobilanthes glandulataNilanthi (Acanthaceae) based on morphological and molecular data, from the Knuckles Forest Reserve.
Morphological and DNA evidence were used to distinguish the new plant species from the other closest plant species, S. lupulina.
When contacted Dr. Rajapakse told The Island that Nelu has medicinal value could be used to treat many ailments. Serving as a watershed, it plays an important ecological role. It also helps maintain soil moisture. Young plants are a delicacy of sambur. Many birds and bees come to drink the nectar of the harvested flowers. Nelu is also the host plant of some butterfly species.
Other team members are 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, Hiruna Samarakoon and Bhagya Hathurusinghe.
During the plant explorations on 22nd April 2016, Nilanthi has found an interesting Strobilanthes population with about 300 individuals growing in the shady places along the stream at Rambukoluwa in the Knuckles Mountain Range. The species named “Strobilanthus glandulataNilanthi” because the epithet glandulata refers to the glandular-hairs on the bracts. It flowers from March to May.
Nearly 450 species of Nelu are spread around the world, most of which are found in tropical and subtropical Asia. With the discovery of the new species, there are about 34 species of Strobilanthes found in the natural environment in Sri Lanka, of which 33 species are endemic to Sri Lanka. Fourteen of these species are protected by the Fauna and Flora Protection Ordinance (FFPO).
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.
The team thanked the Director General, Department of Wildlife Conservation (DWC) for the constant encouragement and facilities provided. They also thanked and Department of Forest Conservation, for permitting them to collect samples and the Agriculture Biotechnology Centre, of the Peradeniya University 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.

Fuel crunch looms
Govt. tells fuel distributors to maintain stocks to ensure uninterrupted supplies
by Saman Indrajith and Norman Palihawadane
The government had instructed private fuel distributors to maintain minimum stocks and ensure uninterrupted supplies to the market, Energy Minister Anura Karunathilaka told Parliament yesterday (06).
Karunathilaka said the Ministry of Energy Secretary had notified the relevant companies of the requirement, following a reduction in supplies by some private distributors, amid higher international fuel prices.
The Minister said private companies had informed the government that they were facing losses because international prices had risen while fuel was being sold, locally, at prevailing prices. As a result, some companies had reduced the volumes released to the market.
The reduced supplies had increased the burden on the Ceylon Petroleum Corporation (CPC), whose share of the diesel market had risen from about 54% to 82%, the Minister said.
“The CPC currently holds an 82% share of the market,” he said, adding that it had increased its supplies, compared with February, to compensate for the reduction by private distributors.
Karunathilaka said the government could not, under the existing agreements with private companies, specify the quantities they should supply to individual filling stations. However, it could require them to maintain minimum stocks in the country.
The Minister said the Energy Ministry had already instructed companies that had failed to maintain the required stocks to take steps to prevent supply disruptions.
The Minister attributed the queues reported at some filling stations to reduced supplies from private distributors, as well as normal variations in fuel distribution. He also said demand for CPC fuel had increased because private companies generally did not provide fuel to dealers on credit, while the CPC offered a three-day credit facility.
“We expect that, as the Ceylon Petroleum Corporation takes on this additional burden, the problem will ease to some extent by Wednesday or Thursday,” Karunathilaka said.
He said instructions had also been issued to increase supplies to CPC filling stations. A special discussion on the issue is scheduled for today (07), with officials of the Energy Ministry and CPC expected to participate,
along with President Anura Kumara Dissanayake.
Meanwhile, Petroleum Dealers’ Association officials have called for an early solution to the supply issue. Association Chairman D.V. Shantha Silva said queues had been reported at many filling stations, mainly those operated by private distributors.
He said the situation was not due to an overall shortage of fuel, but was linked to reduced orders by Lanka IOC, Sinopec and R.M. Parks amid concerns over losses incurred on fuel sales.
The Ceylon Petroleum Private Tanker Owners Association has urged motorists to refrain from panic buying, saying there was no nationwide disruption to fuel supplies.
The government earlier increased fuel prices and introduced a per-litre diesel subsidy following concerns raised by distributors over rising international prices.
