scabrate–verrucate, and rugulate micromorphology.The first two types of sculpturing aremostly limited to the evergreen oaks and can beused to identify fossil evergreen oak pollen,while the last two types can also be seen in manydeciduous oaks. On the other hand, deciduousoak pollen grains have relatively uniform sculpturing,with only two types encountered:scabrate–verrucate and rugulate sculpturing.This sculpturing is mainly present in deciduousoaks, despite its occurrence in some evergreenoaks. An absolute discrimination between evergreenand deciduous oak pollen is thus impossibleand would require additional evidence in theform of macrofossils. The diagnostic criteria areapplied to a Miocene pollen assemblage fromZhejiang Province, eastern China and demonstratethe high diversity of fossil oaks in thevegetation. The fossil pollen includes three morphotaxaof deciduous origin, two morphotaxa ofevergreen habit, and three oaks whose habit isuncertain.2008040054中 国 云 南 蛛 网 花 粉 分 析 = Pollen analysis ofspider webs from Yunnan, China. ( 英 文 ). SongXiao-Yan; Blackmore S; Bera S; Li Cheng-Sen.Review of Palaeobotany and Palynology, 2007,145(3-4): 325-333This study concerns the palynological analysisof 19 spider webs, which were collected fromthe northwestern, central and southern parts ofYunnan, China. Pollen grains and spores of 20taxa belonging to 16 families were recordedfrom northwestern Yunnan and 28 taxa from 23families from central Yunnan. Spider webs fromsouthern Yunnan yielded 28 taxa belonging to25 families from Mengla County, 38 taxa in 34families from Wangtianshu Garden and 11 taxarepresenting 10 families from XishuangbannaBotanical Garden. The pollen grains and sporesextracted from spider webs reflect the distinctcharacteristics of the regional vegetation whichchanges from north to south Yunnan. This demonstratesthe potential of spider webs as a naturaltrap for the study of modern pollen rain.2008040055Pseudolarix amabilis 花 粉 的 描 述 与 区 分 : 古生 态 推 断 和 新 鲜 双 气 囊 花 粉 新 的 鉴 定 标 准 =Description and differentiation of Pseudolarixamabilis pollen Palaeoecological implicationsand new identification key to fresh bisaccatepollen. ( 英 文 ). Zanni M; Ravazzi C. Review ofPalaeobotany and Palynology, 2007, 145(1-2):35-75The differentiation of Pseudolarix from otherbisaccate pollen is considered as a tool to investigatethe fossil history of this genus. UsingLight Microscope (LM) and Scanning ElectronMicroscopy (SEM) we performed a descriptiveand morphometric analysis of Pseudolarixamabilis (Pinaceae) bisaccate fresh pollen grains.Descriptive differentiation characters from Pinusand from other bisaccates have been established.A morphometric differentiation from pine pollenbelonging to Pinus sylvestris type was obtainedthrough a study of twelve living species of Pinus.A new identification key for bisaccate pollengrains of living conifers has been elaborated.Although it is addressed to identification of freshpollen, the proposed descriptive criteria may alsobe applicable to well-preserved fossil material. APliocene site from N-Italy, rich in Pseudolarixcone scales and needles, was used to test the reliabilityof the proposed criteria on fossil pollen.We also identified Pseudolarix pollen from thelacustrine sediments from Massif Central(France), about 3 My.We carried out a complementary evaluation ofthe ecological and climate ranges both of theliving species and of the fossil assemblages thatincluded Pseudolarix. This tree was a componentof the warm-temperate mixed conifers rainforestsof the Cenozoic, a biome yielding, afterconsiderable reduction of floristic diversity,overall conifer decimation, to the modern“mixed mesophytic” and “mixed hardwood”forest types. Although its fossil record reveals awide distribution in the Northern Hemisphereduring the Cenozoic, macrofossils are only scattered.On the other hand, information about thepollen production, aerodynamics and taphonomyof Pseudolarix pollen suggests that this tree isamong the properly or moderately overrepresentedgenera in pollen images from itsnatural habitat. Therefore, its pollen record mayadd clarifications to palaeoclimate reconstructionsof Cenozoic environments.2008040056非 洲 树 木 和 灌 木 花 粉 类 型 数 据 库 = Africanpollen database inventory of tree and shrub pollentypes. ( 英 文 ). Vincens A; Lézine A-M;Buchet G; Lewden D; Thomas A L; Contributors.Review of Palaeobotany and Palynology, 2007,145(1-2): 135-141African pollen data have been used in manyempirical or quantitative palaeoenvironmentalreconstructions. However, the pollen types usedin these studies were not controlled and standardised,preventing the precise understandingof pollen–plant and pollen–climate relation thatis necessary for the accurate quantification ofcontinental scale climate change or ecologicalprocesses in the past. This paper presents asummary of the progress made with the AfricanPollen Database (APD) inventory of plant diversityfrom pollen data extracted from 276 fossilsites and more than 1500 modern samples, with18
