美妙奇特的鸡骨根艺

鸡骨树,它生长在滇东北山区少数地区,分布稀少。它的根材,质地坚硬,色彩多为浅色,中间部分色稍深,也有因枯败而杂夹一些深色纹理的根材。其主要的特点是肌理线条明显突出,多弯转扭曲,且变化多样,给人以泥陷、面揉般的美感,很是新颖独特。有深色纹理相间的根材制作的根艺,层次丰富,富有韵律;无深色纹理相间的,显得淡雅清新、明快亮丽……。总之用鸡骨根材创作的根艺作品独具一格,奇特美妙。以下是本人用鸡骨根材创作的几件作品,供根友们欣赏。

“黑白双蔬”话木耳

木耳首载于《神农本草经》中,被列为＂中品＂,另外还有木菌、树鸡、木蛾等别称。根据训诂学家考证,《神农本草经》成书不会晚于东汉,由此可以推知古人食用木耳的历史非常悠久。李时珍在《本草纲目》中说：＂木耳生于朽木之上,无枝叶,乃湿热余气所生。曰耳曰蛾,象形也。曰鸡,因味似也。……或曰,地生为菌,

Characters and Microscopic Identification of Stems and Leaves of Viburnum Sargenti Koehne

[Objective] This study aimed to study the pharmacognostical properties of medicinal parts of stems and leaves of Viburnum Sargenti Koehne to provide refer- ence for its identification and application. [Method] Methods of characters and micro- scopic identification were used. [Result] Characters, transaction and microscopic characteristics of stems and leaves of V. sargenti Koehne were analyzed systemati- cally. [Conclusion] The experimental results can provide reference for the pharma- cognostical identification, further exploitation and utilization of stems and leaves of V. Sargenti Koehne.

Subtree, TASS and an Analysis of the Genus Caragana

Subtree analysis and three area satements (TASS) procedure are used to deal with the area relationship in historical biogeography. On the basis of the taxon cladogram, the procedure could identify and eliminate the paralogy node and determine the informative subtree. The area relationships are generally illustrated in several subtrees and the consensus tree. The distribution pattern of the genus Caragana comprising about 72 species and occurring in 13 areas, was analyzed by using subtree method and TASS procedure in this study. The results showed seven subtrees representing the area relationships of section and series of the genus, and the consensus tree provided the 13 area relationships. These results are congruent with our former result using component analysis for Caragana.
