Molecular and Genome Evolution in the Malesian Slipper Orchids (Paphiopedilum section Barbata).
Paphiopedilum section Barbata (Cypripedioideae: Orchidaceae) is an evolutionarily young and charismatic group of terrestrial orchids native to the Himalayas, Indochina and Malesia. It contains several interesting species complexes, variable chromosome numbers (2n=28-42) and genome sizes (2C=55-70 pg) with hybrid speciation suspected on the basis of morphological data. In Chapter 1,...Yap, Jing Wei
