At the invitation of the Institute’s director Prof. Xu Zhaifu, when the work was coming to an end, I toured the well-known botanic garden of the Institute in the township of Menglu, which nests in the picturesque district of Xishuang Banna at the southernmost tip of the subtropical territory of Yunnan. In the winter of 1958,I had visited the ever-verdant vicinity to collect floral materials. After almost 37 years, I revisited the botanic garden founded by celebrated展开更多
