Rare plant species rediscovered in Western Ghats after more than 100 years (downtoearth)

A group of Indian taxonomists has rediscovered a wild plant after a gap of nearly 100 years.

Called Ceropegia omissa H.Huber, the species was last seen in 1916. Prior to this, it was seen and collected only on two occasions—in 1835 and 1914. Interestingly, all the sightings have been made in a narrow region, within a radius of about 50 km in southern parts of the Western Ghats.

The area of occurrence of this plant is close to Courtallam (or Kuttalam) in Tirunelveli district of Tamil Nadu, a tourism spot known for its waterfalls.

The region from where it has been found is a biosphere reserve and thus, there would be not much difficulty in launching efforts to conserve it.

The flowers of Ceropegia genus look like a fountain of wax. The scientific name was derived from this aspect: 'keros', meaning wax and 'pege', meaning fountain. Plants of this genus have many common names, including lantern flower, parasol flower, parachute flower, bushman’s pipe, string of hearts, snake creeper, wine-glass vine, rosary vine, and necklace vine. Such flowers are traded and propagated as ornamental plants.

Researchers came across the rare plant while exploring south Indian orchid species Habenaria Wild. The two plants were found growing alongside each other. It took some time before the rare plant was identified as Ceropegia Omissa as not much information about it was available in literature. None seem to have illustrated or photographed the floral details.

In a report on their finding published in the latest issue of journal Current Science, the scientists said, "there is a need for extensive exploration survey to locate newer populations of the species and assess its reproductive ecology to ensure its survival."

The study was conducted by K Prasad of Botanical Survey of India’s Deccan Regional Centre, Hyderabad, P Venu of Environmental Protection Training and Research Institute, Hyderabad and S Kaliamoorthy of National Orchidarium and Experimental Garden, Yercaud.

The Centre has identified floriculture as a sunrise industry and has accorded it 100 per cent export-oriented status. Owing to steady increase in demand for flowers both within and outside the country, it has become one of the important commercial trades in agriculture. Consequently, it has emerged as a high-tech activity taking place under controlled climatic conditions in greenhouses. A main upside of floriculture is that it has a higher potential per unit area than most of the field crops. (India Science Wire)

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”. The Supreme Court on Friday came close to ordering the government not to deport the Rohingya. It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests. The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach i...

"ISRO has capabilities to build geostationary satellites for air quality monitoring” (downtoearth)

Pawan Gupta's findings on trans-boundary movement of pollution (Punjab to Delhi) from biomass burning in 2015 spurred debates. He participated in discussions with Indian regulators early September at the Better Air Quality Conference in Busan on the advantages of using satellite data for air quality monitoring. He explains to Down to Earth how air quality monitoring is done using satellite data. How is satellite data used to measure air pollution? Satellites that provide information on atmospheric pollutants are normally (not always) in the low earth orbits (400-1000 km above the Earth’s surface). A single satellite can carry one or more remote sensing instruments onboard that look down to earth and obtain information about the object in the field of view of satellite sensor. The Earth receives electromagnetic radiation from the sun, which travels through space and reaches the earth-atmosphere system. The radiation then interacts with the Earth’s atmosphere and the surface...

What's ailing Namami Gange programme?(DTE)

Winters are extremely hectic for Sushma Patel, a vegetable grower in Uttar Pradesh’s Chunar town. Her farm is in the fertile plains of Ganga where people grow three crops a year. But this is the only season when she can grow vegetables. And before that, she needs to manually dig out shreds of plastic and wrappers from her one-hectare (ha) farm. “This is all because of the nullah,” she says, pointing at an open drain that runs through her field, carrying sewage from the neighbourhood to the Ganga. “Every monsoon, the drain overflows and inundates the field with a thick, black sludge and plastic debris. We cannot even go near the field as the stench of sewage fills the air,” she says. But Patel has no one to complain to as this is the way of life for most people in this ancient town. About 70 per cent of the people in Chunar depend on toilets that have on-site sanitation, such as septic tanks and pits. In the absence of a proper disposal or management system, people simply dump the faec...
