单蒴盖亚属（Ｍｏｎｏｃａｌｙｐｔｕｓ）是桉树属（ＥｕｃａｌｙｐｔｕｓＬ’Ｈｅｒｉｔｉｅｒ）中第２大的亚属，包括１３４种和９亚种。单蒴盖亚属桉树引种具有很重要的生物地理学意义。１９９０年在云南一平浪林场建立的树种试验，包括王桉（Ｅ．ｒｅｇｎａｎｓ）、斜叶桉（Ｅ．ｏｂｌｉｑｕａ）、大桉（Ｅ．ｄｅｌｅｇａｔｅｎｓｉｓ）、滨河白桉（Ｅ．ｅｌａｔａ）、白腊树桉（Ｅ．ｆｒａｘｉｎｏｉｄｅｓ）、雪桉（Ｅ．ｐａｕｃｉｆｌｏｒａ）、三花桉（Ｅ．ｔｒｉｆｌｏｒａ）、高桉（Ｅ．ｆａｓｔｉｇａｔａ）、布达王桉（Ｅ．ｄｅｎｄｒｏｍｏｒｐｈａ）和缪勒纤皮桉（Ｅ．ｍｕｅｌｅｒａｎａ）。生长量超过同期种植的蓝桉（Ｅ．ｇｌｏｂｕｌｕｓ）。试验规模不大，但具有重要的生态植物地理指示意义。除气候条件比较适宜外，还可能因为试验地前作为云南松，土壤微生物群落比较丰富，尤其是彩色豆马勃（Ｐｉｓｏｌｉｔｈｕｓ）。
Monocalyptus is the second largest genera in EucalyptusL’Heritier, including 134 and 9 subspecies. The introduction of Eucalyptus monocytogenes has a very important biogeographical significance. Tree species trials established in 1990 at Yipinglanglin Farm, Yunnan Province, include E. junans, E. obliqua, E. delegatensis, E. etala, Efraxi-noides, E. pauciflora, E.triflora, E.fastigata, E.dendromorpha and Mueller’s eucalyptus E.muelerana). Growing over the same period planted Eucalyptus (E.globulus). The experimental scale is not large, but it has important geographical significance of ecological plants. In addition to the more suitable climatic conditions, it is also possible that the soil microbial community was rich, especially Pisolithus, because of the pre-experiment as Pinus yunnanensis.
