石笔木的学名考正：Tutcheria championii 还是 T. spectabilis?

为何Tutcheria championii Nakai (1940) 发表较晚, 却被《中国植物志》等志书作为正确学名；而 T. spectabilis (Champ. ex Benth.) Dunn (1908)这更早发表的名称却成了异名？ 笔者在本文解释，根据《国际植物命名法规》，因T. championii这后出替代名发表时曾引用Camellia spectabilis Champ. ex Benth.，而主模式标本因此已包含在内，所以在Tutcheria属内，具相同主模式的T. spectabilis是合法名也具有优先权，应为正确学名。

The glass flowers of Harvard's Botanical Museum

The Botanical Museum of Harvard University houses an extensive collection of entire plants and plant structures modelled in glass with exquisite accuracy. They were made in Germany, over a period of some fifty years commencing 1887, by the Blaschkas, father and son. Although some deterioration is now causing concern, and support is needed for their conservation, they remain a unique example of scientific artistry.     

Survey reveals the situation of Chinese caterpillar fungus resources

Mechanisms of carbon, nitrogen and water changes during restoration and succession in tropical and subtropical forest ecosystems

With the objective of finding answers to some fundamental problems in ecology and forestry, Prof. ZHOU Guoyi and his colleagues from the CAS South China Botanical Garden set out to clarify whether the oldgrowth forests are actually carbon sinks; how the forest ecosystems, either successional or rehabilitative, react to the nitrogen deposition scenarios and whether there are different reactions working as mechanisms between the mature and immature forest ecosystems. Moreover, together with the studies on the cycling of carbon, nitrogen and water, they conducted a systematic analysis to understand the mass flow, ecosystem service function and their changes against the background of the global change. Through long-term field observation in more than 50 sites of typical ecosystems and extensive investigation, the scientists have achieved a series of remarkable research results and received a 2nd prize of the National Natural Science Award in 2007.

长筒石蒜的染色体核型分析

A karyotypic analysis of Lycoris longituba Y. Hsu et Fan was carried out. The voucher specimen, Z. G. Mao 10501, is preserved in the Herbarium of Hangchow Botanical Garden. The chromosome number in root tip cells of the species is found for the first time to be 16, among which 6 are large, V-shaped with submedian primary constric- tions, and the other 10 are short, rod-shaped  with terminal primary constrictions. Photomi- crograph of the chromosome complement and idiogram are given in Fig. 1-3 respectively. The karyotype formula of the species is therefore 2n=16=6m+6t+4t (SAT) in the light of the chromosomal terminology defined by Levan and al.[5]      Based on the view stressed by Jones[3] and Brandham[4], successive fusion of the ch- romosomes should be taken as the essential mechanism for karyotype evolution and specia- tion in Lycoris. Reciprocal translocation, with the loss of one of the centromeres, might be the mechanism of origin for a V chromosome. It is, then, suggested that the decrease in ch- romosome number as a result of fusion of the rods with terminal or subterminal primaryconstrictions has taken place in the speciation of L. longituba.
