The study of land bridge based on con- tinental drift1) and long-distance dispersal are gaining increasing attention in biogeography. We review several major dispersal theories including the Mal- pigiacea route, patterns of chameleon dispersal and the floating island model. The Malpigiaceae route indicates that the Malpigiaceae family originated in northern South America and that members of several clades migrated into North America and subsequently moved via north Atlantic land connections into the Old World starting in the Eocene. This route may also explain many other pantropic disjunction patterns, including some Chinese plants disjunctions, involving South America. Not all biogeographical distribution patterns can be explained by vicariance theory, so more research, including chameleon distribution, has recently focused on long-distance dispersal. The lat- est analyses suggest that chameleons have dis- persed over long-distances from Madagascar on several occasions. The floating island model would explain flora and fauna similarities between South America and Africa. Studying long-distance dispersal mechanisms is important for understanding distribu- tion patterns and even the spread of pandemics. More research on the specific implications of long- distance dispersal for biogeography is necessary.

Using data from previous research on Quercus sect. Heterobalanus, the coexistence approach to Xix-abangma and Namling fossil sets, and altitudinal ranges of vegetation presented by fossil floras, a re-view and reevaluation have been made of existing theories on the uplift of the Himalayas, especially the palaeoaltitudes of Xixabangma and Namling in Tibet. The Xixabangma fossil set has a palaeoaltitude range of 2500―3500 m, and has risen 2200―3400 m since the Pliocene. The lower and upper assem-blages of the Miocene Namling had palaeoaltitudes of 2500―3000 m and 2800―3000 m, respectively. Therefore, Namling has risen at least 1300 m since the Miocene, thereby challenging some existing theories that suggest Namling has been static since the Miocene.

Eighty years ago, a botanical institute called"the Yunnan Provincial Institute of Agricultural and Forestry Botany"was jointly founded by the Jingsheng Biology Institute and the Yunnan State Department of Education in Kunming. At that time, the Heilong Dragon Park became the institute's home (Fig. 1) and the research conducted there mostly focused on taxonomy and economical botany. When the institute came under the auspices of the Chinese Academy of Science, it still had fewer than 20 staff members.
