| 摘 要： | 本文对龙眼(桂圆)Dimocarpus longan Lout，和龙荔(疯人果)D．confinis(How et Ho)H．SLo的毛被类型和果实形态进行了详尽的比较观察。龙眼的营养和繁殖体上具分枝的星状毛，果皮表面具平滑瘤状或泡状突起；而龙荔的毛被则为单生柔毛或腺毛，果皮表面具圆锥状小刺。这两个种之间基本没有形态过渡，是分类学上区别明显的种。本文还报道了对商业部门送检样品的鉴定结果。龙眼毛被类型和果实形态在送检样品中均可观察到，而且在这些样品果皮表面未见有组织断裂及破损痕迹，因此，它们不可能是由龙荔果实加工处理的假冒商品，而是真正的桂圆。

| Abstract: | Examination on hairs and fruits of the Dimocarpus longan Lour. (Guiyuan) and
D. confinis (How et Ho) H. S. Lo (magic fruit) was carried out. The fruit of D. longan
was found to be of smoothly colliculate or granulate protuberances and typical tuft hairs on
the surface, and the leaf was also of tuft hairs on the lower surface. However, the fruit of
D. confinis was of dense and hard aculeate protuberances and simple and glandular hairs on
the surface, and the leaf was also of the same kind of hairs on the lower surface. These char-
acteristics of D. longan can been easily detected in samples of commercial fruits, which were
misidentified as the fruits of D. confinis. Moreover, the fruit surface of Guiyuan Sampled
from the markets had no any artificially destroryed trace, which indicated that they were
not forged through the processing of the fruits of D. confinis, and thus they were trueGuiyuan, the fruit of D. longan. |
