    Forest history in Yunnan, or the history of forest degradation there, centers on the forests surrounding its fertile basins. The history of exploitation of forest resources, mainly by the Han people who inhabit the basins, is clearly engraved in these forests.
     During the Great Leap Forward and the Cultural Revolution, these forests were damaged without restriction or protection. In this time of political confusion, people uprooted forests without thought for the future.
     Following this ecological disaster, the most effective policy for reforestation was division of the forest. Communally managed forests were divided among individual families, who were expected to replant the depleted forest for their own economic interest.
     Bare and eroded forest land could only be replanted with a limited number of pioneer trees, including species of Eucalyptus. Fortunately, eucalypts turned out to be valuable for the oil that could be extracted from their leaves, and thus they began to be widely planted.
     Given the limited demand for eucalyptus oil, however. the economic value of eucalypts may not remain high. Here, I discuss the future of eucalypt plantations and the forests surrounding basins.

    中国雲南省において,ゴマノハグサ科クワガタソウ属カワヂシャ節の植物を調査をした.その結果,染色体数が異なる3種類の植物が観察された.高度が約2,500 mより高い4箇所で採集した個体は2n=36であり,形態的な特徴は,中国植物誌(Tsoon and Hong 1979)や欧米のフロラ(Hartl 1975, Hitchcock et al. 1959)などに記載されているVeronica anagallis-aquatica L. とよく一致していた.これに対して,日本の平地に生育しているV. anagallis-aquatica(Tanaka 1995)は,花冠の紫色がより濃い点や,花冠の直径や花柱の長さがより大きい点で異なり,本種全体から見れば,むしろ特殊な集団であると思われる.高度が約2,500 mより低い3箇所で採集した個体は2n=54であり,カワヂシャVeronica undulata Wall. とするのが妥当だと思われる.中国での2n=54の記録はこれが最初である.日本で生育しているV. undulata とは全体的によく似ていた.1箇所ではあるが,麗江地区の水田を流れる小川の水際において,2n=45の染色体数の個体があった.外部形態は,極端に長い花序に不稔の花を多数つけており,雑種の特徴を示していた.採集地点の高度は2,325 mであるので,上記で明らかとなった,2n=36のV. anagallis-aquatica と2n=54のV. undulata がともに生育している可能性があり,また,体細胞染色体数が45であることから判断して,この雑種は日本と同様に,これら2種を母種として形成されたVeronica × myriantha Tos. Tanaka であると推定される.中国における雑種の報告はこれが最初である.

    To the north of old Dali Castle in present day western Yunnan's Dali Bai People's Autonomous Region lies Shengyuan Temple 聖元寺 in the mountainous region of Xizhou-zhen 喜洲鎮. The temple, which was built in the mid-fifteenth century, holds a manuscript entitled Baiguo Yinyou 白国因由 (Origins of the Bai Kingdom), which was authored by the temple's abbot in 1706. According to the source, in the year 615 the Boddhisattva Avalokite svara (Guanyin 観音) appeared in Dali in the guise of a Buddhist monk from India, and after vanquishing a demon that was reeking havoc in the region, Guanyin enthroned Xinuluo 細奴羅 as the founder of the Nanzhao 南詔 Kingdom, converted his subjects to Buddhism, and after the fall of the Nanzhao Kingdom, helped Duan Siping 段思平 to become the first king of Dali kingdom. In the present article, the author takes up Baiguo Yinyou in order to how the Guanyin legend, which is a symbol of the unification of the Nanzhao and Dali Kingdoms, changed and was preserved over time among the Bai people during the Ming and Qing periods. This is because Baiguo Yinyou is the definitive account of the Guanyin legend for the Bai people during those later periods. The significance of Baiguo Yinyou is not that is accurately depicts the spread of Buddhism in Yunnan or any other historical facts. Rather, it is significant because beliefs centered upon the legend as a legitimization of the unification of the region since Nanzhao times were to be preserved among the people of Dali well into Ming times, then during the Qing period, they were consolidated into a general historical image of the kingdom of "Baiguo."
