Wuwei Camellia (武威山茶), a Taiwanese endemic species which had been not seen since 1930s and was believed extinct, was rediscovered early this year in southern Taiwan, researchers said yesterday.
The discovery was made by ecologists involved in a conservation project sponsored by the Council of Agriculture (COA).
Since last year, dozens of ecologists involved in a project to classify and map vegetation have been collecting rare species in remote areas islandwide. In January, participants in the project were inspired by the rediscovery of a camellia, once thought to be extinct, in southern Taiwan.
When conducting research on Chenli Mountain in Pingtung County, ecologists from the National Pingtung University of Science and Technology spotted unusual blossoms. Samples they collected from two trees were identified as Wuwei Camellia, which has not been seen since the 1930s.
At a press conference in Taipei, tissues from the tree cultivated in tubes were shown to the media.
"We don't know how long they will survive. But we should keep alert to the fragility of nature," said Li Chia-wei (李家維), director of the National Museum of Natural Science.
According to Hsieh Chang-fu (謝長富), professor of the Institute of Ecology and Evolutionary Biology at National Taiwan University, Wuwei Camillia, whose scientific name is Camellia buisanensis Sasaki, was first recorded by Augustine Henry, an Irish physician and plant collector, in 1892 in southern Taiwan. The sample of the plant, which had not been classified, was later given to the Smithsonian Institution in Washington.
Hsieh said that available documents suggested the camellia was collected several times in the late 1910s and early 1920s. But it had not be appropriately classified until 1931, when Japanese ecologist Syuniti Sasaki studied it. Sasaki's research paper suggested the plant grew on Wuwei Mountain.
"Since the 1930s, however, no record of the camellia being observed had been reported," Hsieh said.
The mystery aroused the curiosity of the Taiwanese ecologists. Over the past eight years, Hsieh and other ecologists had tried to determine the location of the mountain.
Since the Wanchin Basilica in Wanchin Village, Pingtung County, was once an inn for Western researchers, ecologists decided to explore the mountains nearby. Finally, they concluded that Wutsang Mountain (
"The rapidly changing environment resulting from land use in hills about 900m above sea level made it impossible for the Wuwei Camellia to survive," Hsieh said.

"We can't deny that more species became extinct because of human-centered development," King said.
King said that monitoring by non-governmental organizations, academic research and good legislation are the three pillars of ecological conservation ensuring biological diversity.

"So far we have rediscovered 29 species in Taiwan. They were all once thought to be extinct," Yen said.
An essay competition jointly organized by a local writing society and a publisher affiliated with the Chinese Communist Party (CCP) might have contravened the Act Governing Relations Between the People of the Taiwan Area and the Mainland Area (臺灣地區與大陸地區人民關係條例), the Mainland Affairs Council (MAC) said on Thursday. “In this case, the partner organization is clearly an agency under the CCP’s Fujian Provincial Committee,” MAC Deputy Minister and spokesperson Liang Wen-chieh (梁文傑) said at a news briefing in Taipei. “It also involves bringing Taiwanese students to China with all-expenses-paid arrangements to attend award ceremonies and camps,” Liang said. Those two “characteristics” are typically sufficient
A magnitude 5.9 earthquake that struck about 33km off the coast of Hualien City was the "main shock" in a series of quakes in the area, with aftershocks expected over the next three days, the Central Weather Administration (CWA) said yesterday. Prior to the magnitude 5.9 quake shaking most of Taiwan at 6:53pm yesterday, six other earthquakes stronger than a magnitude of 4, starting with a magnitude 5.5 quake at 6:09pm, occurred in the area. CWA Seismological Center Director Wu Chien-fu (吳健富) confirmed that the quakes were all part of the same series and that the magnitude 5.5 temblor was
The brilliant blue waters, thick foliage and bucolic atmosphere on this seemingly idyllic archipelago deep in the Pacific Ocean belie the key role it now plays in a titanic geopolitical struggle. Palau is again on the front line as China, and the US and its allies prepare their forces in an intensifying contest for control over the Asia-Pacific region. The democratic nation of just 17,000 people hosts US-controlled airstrips and soon-to-be-completed radar installations that the US military describes as “critical” to monitoring vast swathes of water and airspace. It is also a key piece of the second island chain, a string of
The Central Weather Administration has issued a heat alert for southeastern Taiwan, warning of temperatures as high as 36°C today, while alerting some coastal areas of strong winds later in the day. Kaohsiung’s Neimen District (內門) and Pingtung County’s Neipu Township (內埔) are under an orange heat alert, which warns of temperatures as high as 36°C for three consecutive days, the CWA said, citing southwest winds. The heat would also extend to Tainan’s Nansi (楠西) and Yujing (玉井) districts, as well as Pingtung’s Gaoshu (高樹), Yanpu (鹽埔) and Majia (瑪家) townships, it said, forecasting highs of up to 36°C in those areas
