2012-07-27Reintroduction of Tigridiopalma magnifica, a Rare and Critically Endangered Herb Endemic to ChinaThe main findings are as following:Twelve locations with populations of T. Magnifica only grows in the surface soil on stone walls or rocks under the canopy of secondary forests and plantations and has no specific associated plant species. After 11 months survival rate was 40–58% but survival was higher and plantlet crowns were larger at the lo... Tigridiopalma magnifica, a perennial herb and the only species in the genus Tigridiopalma (Family Melastomataceae) is rare, and endemic to China, where it is categorized as Critically Endangered on the national Red List. During past 7 years, Dr REN Hai and Dr. ZENG Songjun co-operated to research the reintroduction of the species. The main findi...Read More -
