A palynotaxonomic study of the genus Filipendula （Rosaceae）

Pollen grains from 15 species （18 taxa） of the genus Filipendula were examined with light and scanning electron microscopy. It was revealed that the pollen grains are isopolar, tricolporate, with scabrate or scabrate-microechinate surface. The pollen morphology was compared with the conventional classification systems of the genus by different authors, and supported Shimizu＇s system （1961）, in which the genus was divided into three subgenera. The monotypic subgen. Hypogyna is characterized by pollen lacking fastigium and thickened costae colpi. The other monotypic subgen. Filipendula differs from others by pollen having larger grain, larger pore size, longitudinally elliptic fastigium and thickened costae colpi. The largest subgen. Ulmaria is distinguished by pollen having rounded or latitudinally elliptic fastigium and thickened costae colpi. Sectional classification was not supported by the pollen morphology due to insufficient variability. Key words Filipendula, palynology, systematics.

芸香科山小橘属一新种——长瓣山小橘

Glycosmis longipetala F. J. Mou ＆ D. X. Zhang is described from Guangxi and Yunnan provinces in southwestern China. The new species is similar to G. cochinchinensis （Lour.） Pierre ex Engl. by its simple leaves, but distinguishable in having long-elliptic or oblanceolate （vs. ovate） leaves, long-ovoid to ellipsoid （vs. ovoid） floral buds, ovaries with many tubercles （vs. smooth） and glabrous （vs. pubescent） stamens. The pollen grains of the new species are 23.9±3.09 （20.8-27.0）×22.0±1.80 （20.4-24.4）μm in size with reticulate exine ornamentation in equatorial area and foveolate in polar area. The chromosome number of the new species is 2n=72.     

晶圆盘菌属的一个中国新记录种

Orbilia Fr. and Hyalorbilia Baral & G. Marson are the only genera currently accepted in the family Orbiliaceae which was established by Nannfeldt (Baral, 1994; Kirk et al., 2001). Hyalorbilia was erected by Baral and Marson (2001) based on unstalked asci arising from crosiers, with hemispherical apices without wall thickenings, some bipolar-symmetrical globose inclusion bodies in ascospores (living state), asci and paraphyses cohere in a gelatinous matrix, paraphyses with not or only slightly inflated apices, and an ectal excipulum of horizontally oriented textura rectangular.     

Pollen Morphology of Tundra Shrubs and Submarginal Plants from Barrow, Alaska

Investigation of plant morphological features, pollen, and habitat have been made for two shrub species from Barrow, Alaska, namely Dryas integrifoila M. Vahl and Salix rotundifolia Trautv., both of which are endemic to the Arctic floristic area. The former species has small lanceolate or plate leaves, whereas the latter has rounded leaves with distinct veins, rich in vitamin C. Both have dwarf and sprawling habits. Pollen studies showed that the pollen grains of the two species are spheroidal to sub-spheroidal or prolate. The type of aperture was tricolporate; pollen size 26.3-31.3 μm; ornamentation finely reticulate under a light microscope （LM） and strlate-reticulate under a scanning electron microscope （SEM） for D. integrafoila and finely reticulate under the LM and SEM for S. rotundifolia. Comparisons were made between the pollen from the same species from Arctic collections with those from China and Japan. Investigation of pollen morphology of tundra plants can provide significant data for comparative studies of fossil pollen and for the reconstruction of paleovegetation and paleoclimate in the Barrow area.

Validation of the name Callicarpa bodinieri var.iteophylla (Lamiaceae)

Callicarpa bodinieri H.Léveillé var.iteophylla C.Y.Wu,var.nov.Type:China.Yunnan:Mengla,1953-06-03,Yong-Shu Wang 27 (holotype,KUN 0484466!;isotype,KUN 0484467!).Validating diagnosis:Those ofCallicarpa bodinieri H.Léveillé var.iteophylla C.Y.Wu,Fl.Yunnan.1:406.1977.Callicarpa bodinieri H.Léveillé var.iteophylla C.Y.Wu is endemic to southern Yunnan province of China,and it occurs in mixed forests at altitudes between 600 and 1600 m.This new variety is easily distinguished from var.bodinieri and var.rosthornii (Diels)Rehder in that the leaf blade is lanceolate,oblanceolate,or obovateoblong,and 2-4 cm wide (vs.narrowly elliptic,elliptic,or ovateelliptic,and 4-7 cm wide in var.bodinieri),and subglabrous on both surfaces (vs.abaxially grayish stellate pubescent in var.rosthornii).
