The location of stomata and the structural details of exostome teeth and endostome segments are among the most important taxonomic features used for identifying Orthotrichum species. Certain species pairs (e.g. O. stramineum vs. O. pallens; O. pumilum vs. O. stellatum) are distinguished based on the presence or absence of hair on the vaginula. The authors have shown that this feature is not always appropriate for species identification. Some specimens of O. affine, O. anomalum or O. speciosum were found to have a hairy vaginula, although this feature is not included in their description. The confusion with species determination was resolved in a subsequent DNA analysis of the specimens. The reliability of this character is briefly discussed in the paper.
Redescription of Chronogaster boettgerii Kischke, 1956 is provided. The male of this species was found for the first time, and herein is described and illustrated. Chronogaster boettgeri Kischke, 1956 is distinguished by its amphids circular at the surface and forming a single spiral with a dorsal break, presence of 3 caudal glands arranged in tandem, absence of lateral longitudinal lines, lack of vacuolated lateral glandular bodies, tail tip of female with single, almost ventral and straight mucro; male is distinguished by tail terminus devoid of mucro and absence of tuboid preanal supplements.
This work presents electrophoretic seed globulin data obtained for 173 accessions representing nine Vicia species of the section Faba, which were already investigated for electrophoretic seed albumin patterns (PRZYBYLSKA, ZIMNIAK-PRZYBYLSKA, in press). Electrophoretic analysis of seed globulins was performed using sodium dodecyl sulphate - polyacrylamide gel electrophoresis (SDS-PAGE). In the examined material totally 38 well-defined polypeptide bands, in the relative molecular mass range of 19-61 kDa, were distinguished. The presence/absence of particular bands was recorded for each analysed individual. The electrophoretic data were used for hierarchical grouping of the examined taxa, based on calculated Bhattacharyya distances. V. bithynica proved to be the most distinctive member of Vicia section Faba. In turn, V. faba was clearly different from species of the V. narbonensis complex. Taxa of this complex formed two clusters: one consisting of V. narbonensis varieties and another - of the remaining species. In the latter group, V. serratifolia appeared to be rather distantly related to V. eristalioides, V. galilaea, V. hyaeniscyamus, V. Johannis and V. kalakhensis. The obtained results are compared with the corresponding seed albumin data and discussed with reference to taxonomie relationships in Vicia section Faba.
The Warsaw Museum and Institute of Zoology contains an important collection of Coleoptera Brentidae. This material includes many types of species described by Richard Kleine, one of the most famous brentid specialists, whose collection, before the second World War, was held in Stettin. In our study of the collection, we designated lectotypes for the following species: Baryrhynchus (Eupsalomimus) schroederi Kleine, 1914; Corporaalia baryrrhynchoides Kleine, 1921; Gyalostoma jucundum Kleine, 1914; Spatherhinus grandis Kleine, 1914; Eupsalithopsis spatherinoides Kleine, 1914; Amorphocephala intermedia Kleine, 1918; Cerobates (Cerobates) aequalis Kleine, 1922; Hypomiolispa bickhardti Kleine, 1918; Hypomiolispa dentigena Kleine, 1918; Hypomiolispa rugosa Kleine, 1918; Miolispa adversaria Kleine, 1922; Miolispa nigricollis Kleine, 1919; Paratrachelizus afflictus Kleine, 1922; Leptocymatium observans Kleine, 1941; Thaumastopsis separata Kleine, 1941; Heterothesis elegans Kleine, 1914.

Pollen morphology of Amygdalus L. [Rosaceae] in Iran

88%
Pollen grain of 16 species and three hybrids of the genus Amygdalus L., representing two subgenera and two sections distributed in Iran were examined by light and scanning electron microscopy. All pollen grains are tricolporate. The shape of grains varies from subprolate through prolate. Regarding outline, in polar view, pollen grains are triangular-circular and in equatorial view, elliptic. Regarding sculpturing of exine, the frequent type like many members of family Rosaceae is striate with or without perforations that can be subdivided into three subtypes: type I (A-B), type II (A-B) and type V. In three species, A. trichamygdalus, A. spinosissima and A. orientalis, exine sculpture type is completely different. In the first species is rugulate, in the second species is reticulate and in A. orientalis, it is gemmate-perforate. Ornamentation of ridges (muri) in the striate sculpture is parallel to ectocolpus. Number of perforations in tectum, diameter of them, striae intervals and the thickness of ridges varies among studied taxa. The striae have different depth and slope. Results showed that among pollen grain characters, shape is useful character solely for separating of taxonomic ranks in Iranian Amygdalus specially in subgeneric or section level.
