An exhibition on grasses and cereals and their uses in daily life opened yesterday at the Endemic Species Research Institute in Nantou County.
Poaceae, or grasses, have more than 10,000 species and can be seen across various geographies, as they cover one-third of the Earth’s land mass, institute researcher Chen Chih-hui (陳志輝) said.
Well-known poaceae include bamboo, sugarcane, lawn and ornamental grasses, and cereal crops such as maize, wheat, rice, barley and millet, Chen said, adding that they provide more than 40 percent of the calorie needs of the global population.

“Taiwan is situated where the tropical zone and temperate zone converge, so varieties of poaceae native to different climate zones can be seen here, and Taiwanese make good use of them,” he said.
Showing a basket weaved with bamboo fibers, he said such baskets are called gam-a (柑仔) in Hoklo (commonly known as Taiwanese) and gave the traditional grocery store its name gamadiam (柑仔店), where merchandises and fresh produce were put on the baskets either for display or for drying.
The exhibition includes a collection of rice species cultivated in the nation, as well as other grasses that are an integral part of Taiwanese’s daily life.
In a yard designed in the traditional Hokkien architecture, necessities made with grasses are displayed, such as a thatched roof, brooms, furniture and farming tools made with sorghum, silver grass, millet and bamboo.
Poaceae are a rising star in the biofuel industry, as large species of silver grass have been studied and used for power generation, Chen said.
Elephant grass, one of the large, foreign silver grasses that has spread across the nation, is used to make biofuel, and Brazil built the first power plant that runs solely on elephant grass biomass, as the species has higher biofuel efficiency than sugarcane, he said.
“Human civilization relies on domesticating different poaceae species, but people too often ignore the unpresuming plants and turn their attention to woody plants, so the exhibition was organized to reintroduce the public to the familiar plants,” he said.
The exhibition is to run through the end of November.
SPEEDING ELETRIC VEHICLES: Available without license requirements, the low-cost vehicles, especially if illicitly modified, can often reach a dangerous speed The government should crack down on illegal electric bicycles and scooters, the non-profit Consumers’ Foundation said on Friday, citing research on the potentially dangerous speed of the vehicles. Electric bicycles and lightweight electric scooters have gained popularity as they do not require registration and riders do not need licenses, the foundation said, adding that as many as 40 percent of them can reach speeds exceeding the legal limit of 25kph for non-licensed two-wheelers. Some consumers also purchased legal electric vehicles and modified them to reach higher speeds, it said. “If the government does not step up efforts to confiscate these

NEW CASE REPORTED: A man who returned from South Africa on a flight with the nation’s 460th and 461st cases has now tested positive for the disease The Central Epidemic Command Center (CECC) yesterday said that there is no need to test all arrivals to the nation for COVID-19, a policy the Executive Yuan supports. The center reported one new imported case, bringing the nation’s tally of confirmed cases to 477. The new case is a Taiwanese man in his 60s who on July 25 returned from South Africa, said Centers for Disease Control (CDC) Deputy Director-General Chuang Jen-hsiang (莊人祥), who is also the CECC’s spokesman.

Minister of Foreign Affairs Joseph Wu (吳釗燮) yesterday tweeted a welcome to Somaliland’s first representative to Taiwan, Mohamed Omar Hagi Mohamoud, who arrived on Friday. Mohamoud had “braved Chinese pressure” to take up his new post, Wu wrote. “The fact ‘sovereignty & friendship aren’t for sale’ deserves international recognition,” referring to a Somaliland media report earlier this month that Somaliland President Muse Bihi Abdi had rejected an offer by the Chinese government in exchange for ending its rapprochement with Taiwan. Wu also thanked the US National Security Council (NSC) for praising Taiwan-Somaliland ties. A council tweet on July 10 praised Taiwan
