Allium olivieri Boiss. (Alliaceae) is reported as a new record for Turkish flora. It was identified using the collected specimens and Flora orientalis, Flora of Iraq and Flora Iranica. The detailed description, illustrations, geographical distribution, habitat, status of IUCN extinction risk and some comments and discussions on the taxonomy of the species are given.

Genetic differentiation of Calypogeia muelleriana s.l. was studied using isozyme analysis. Two forms of this species: typical and atypical were reported from Poland. The 10 putative loci in 7 enzyme systems were analyzed in 58 samples: 34 of the typical and 15 of atypical form. The isozyme studies revealed that the typical and atypical forms of C. muelleriana in Poland are clearly genetically different. Typical plants morphologically correspond to the type specimen of C. muelleriana, but atypical form is a new, genetically distinct but unrecognized so far taxon. Each group is defined by several fixed alleles present in all populations. The UPGMA dendrogram based on Nei’s genetic distances shows that both taxa (C. muelleriana and the newly detected taxon) clearly differ from C. azurea – the species used as a reference group. Genetic distance among two groups of C. muelleriana (D = 1.093) was almost the same as among C. azurea and the newly detected taxon (D = 1.060). Genetic distance among C. azurea and the typical form of C. muelleriana was the lowest (D = 0.628).

The Early Triassic witnessed the highest taxic diversity of coelacanths (or Actinistia), a clade with a single living genus today. This peak of diversity is accentuated here with the description of a new coelacanth discovered in the lower Spathian (Upper Olenekian, Lower Triassic) cropping out in the Tulcea Veche (Old Tulcea) promontory, in the city of Tulcea, in North Dobrogea, Romania. The bone remains were preserved in a block of limestone, which was chemically dissolved. The resulting 3D and matrix-free ossifications correspond mostly to elements of the skull and branchial apparatus. Posterior parietals, postparietal with associated prootic and basisphenoid allow a precise description of the neurocranium. Ossifications of the lower jaw, together with branchial and pectoral elements, complete the description of this coelacanth and support the coining of a new generic and specific name, Dobrogeria aegyssensis. A phylogenetic analysis of actinistians with the new species recovers clades which were found in most recent analyses, i.e. the Sasseniidae, the Laugiidae, the Coelacanthiformes, the Latimerioidei, the Mawsoniidae and the Latimeriidae, and identifies the new taxon as a non-latimerioid coelacanthiform.

We describe a new avian taxon (Sanshuiornis zhangi gen. et sp. nov.) from Middle Eocene black oil shales in the Huayong Formation of Guangdong Province, south China. The specimen consists of a distal tibiotarsus and a complete foot with tarsometatarsus and pedal digits in articulation. A preliminary phylogenetic analysis does not resolve the affinities of the fossil, but the bones show resemblances to some “ciconiiform” birds. The peculiar hypotarsus morphology, which is block−like and exhibits four cristae, resembles that of the early Eocene Rhynchaeites, which is a stem group representative of the Threskiornithidae. The new Chinese fossil has, however, proportionally longer legs than Rhynchaeites and its phylogenetic affinities probably cannot be resolved without further material.
