Dioecism of the genusCallicarpa (Verbenaceae) in the Bonin (Ogasawara) Islands

The morphology and function of the flowers of three species of the genusCallicarpa, C. glabra, C. nisnimurae andC. subpubescens, endemic to the Bonin Islands, revealed that all three species were dioecious. Male plants had short-styled flowers with sterile ovaries, while female plants had long-styled flowers with non-germinating inaperturate pollen grains. Such dioecism has never been reported from the family Verbenaceae. This curious sexual system with non-germinating pollen grains may have been maintained as a reward to insect pollinators.     

On the discussion of the wing venation of (Archae)Orthoptera (Insecta)

Alternative current approaches to homology and nomenclature of the insect wing venation are discussed. The differences between the opposing viewpoints are found to be not as deep as they have sometimes been supposed to be, and more so, there are some observations that could help to smooth current contradictions. However, this requires an understanding of the evidence presented by the disputants and, particularly, an understanding of their terminology.     

On the fauna of chironomidae (Diptera) of the Hrazdan Basin (Armenia)

A faunistic review of larvae and pupae of chironomid midges (Diptera, Chironomidae) from 15 habitats in the Hrazdan River valley (Armenia) is presented. The revealed fauna includes 40 species from 20 genera and 6 families and tribes. Diploid chromosome numbers are specified for 24 species from 13 genera and 4 subfamilies; 23 species from 14 genera and 4 subfamilies are reported from the region for the first time. Predominant oligotrophic status is confirmed for most of the reservoirs studied.     

On the Structure of the Corpuscles of de Quatrefages (Branchiostoma lanceolatum (P))

Corpuscles of de Quatrefages in the rostral connective tissue of amphioxus have been serially sectioned and examined in the electron microscope. It is shown that each corpuscle is composed of one or a few main cells separated and enveloped by sheath cells. From the main cell two cilia protrude into a lumen formed by a bulge in the sheath. The ciliation of the main cell and its axonic continuation into one of the associated nerves suggests that this cell is a primary sensory neurone and the corpuscles of de Quatrefages probably mechanoreceptors.     

Hematology of the Norwegian Lemming (Lemmus lemmus(L.))

Basic hematological parameters of laboratory-reared Lemmus lemmus have been investigated. The results have been summarized together with those from ten other species of microtine rodents. Climatic conditions, especially the microclimate of the subnivean air space, have been considered to offer possible explanations for the higher values in L. trimucronatus compared to L. Lemmus.
