Tse Tsun Yu
Te-tsun Yü (1908–1986) was a Chinese botanist, specialising in Spermatophytes and Phanerogams, particularly in the Yunnan and Sichuan provinces of China, which have the most diverse flora in China. Education Yu was taught by Hu Xiansu. Career Yu was a co-founder of the Kunming Institute of Botany. He worked as editor of the Flora Reipublicae Popularis Sinicae and director of the Institute of Botany at the Chinese Academy of Sciences. He was a prolific collector of plant specimens in Yunnan, making expeditions into the largely unexplored mountains in the north west of the province. Thousands of specimens he collected were exported to Arnold Arboretum in Boston, Massachusetts and Royal Botanic Garden Edinburgh The Royal Botanic Garden Edinburgh (RBGE) is a scientific centre for the study of plants, their diversity and conservation, as well as a popular tourist attraction. Founded in 1670 as a physic garden to grow medicinal plants, today it occupies ... who funded th ...

Rosaceae
Rosaceae (), the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus ''Rosa''. Among the most species-rich genera are ''Alchemilla'' (270), ''Sorbus'' (260), '' Crataegus'' (260), ''Cotoneaster'' (260), ''Rubus'' (250), and ''Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds. However, all of these numbers should be seen as estimates—much taxonomic work remains. The family Rosaceae includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and shrubs ...

Photinia
''Photinia'' () is a genus of about 30 species of small trees and large shrubs, but the taxonomy has recently varied greatly, with the genera ''Heteromeles'', ''Stranvaesia'' and ''Aronia'' sometimes included in ''Photinia''. They are a part of the rose family (Rosaceae) and related to the apple. The botanical genus name derives from the Greek word photeinos for shiny and refers to the often glossy leaves. Most species are evergreen, but deciduous species also occur. The small apple-shaped fruit has a size of 4 to 12 mm and forms in large quantities. They ripen in the fall and often remain hanging on the bush until well into the winter. The fruits are used as food by birds, which excrete the seeds with their droppings and thereby distribute the plant. The natural range of these species is restricted to warm temperate Asia, from the Himalaya east to Japan and south to India and Thailand. They have, however, been widely cultivated throughout the world as ornamentals for their ...
