<Emphasis Type="Italic">Barleria compacta</Emphasis>: a new species in <Emphasis Type="Italic">Barleria</Emphasis> sect. <Emphasis Type="Italic">Prionitis</Emphasis> (Acanthaceae) from Somalia

Following a re-examination of the material treated under Barleria brevispina (Fiori) Hedrén in the recent Flora of Somalia account of the Acanthaceae, it is concluded that two distinct species are involved and Barleria compacta Malombe & I. Darbysh. is described here from north-eastern Somalia. Its affinities and conservation status are discussed.     

<Emphasis Type="Italic">Rhynchospora galeana</Emphasis>, a new name for <Emphasis Type="Italic">Rhynchospora breviseta</Emphasis> (Gale) Channell (Cyperaceae)

We propose the new name Rhynchospora galeana to replace the illegitimate later homonym R. breviseta (Gale) Channell. Rhynchospora galeana is a member of section Plumosae. It grows in savannas and pinelands in the southeastern U.S.A. and the Greater Antilles.     

<Emphasis Type="Italic">Maireina afibulata</Emphasis> and <Emphasis Type="Italic">M. attenuatipilis</Emphasis>, new members of the cyphelloid genus <Emphasis Type="Italic">Maireina</Emphasis> (Basidiomycota,Agaricomycetes)

Maireina afibulata and M. attenuatipilis are proposed as new members of the recently revised genus Maireina, one of the few anatomically well-studied cyphelloid groups in the Basidiomycota. Maireina species have brownish basidiomes, smooth, parietally unpigmented spores, and are characterized by non-ramified external hyphae with more or less thick, yellow to brown cell walls and distinct crystalline incrustations that always include their distal ends. A key to the species of the genus Maireina is presented, and M. afibulata as well as M. attenuatipilis are described and discussed in detail. Taxonomic novelties: Maireina afibulata Bodensteiner, M. attenuatipilis Bodensteiner

Revision of the Endemic Hawaiian genus <Emphasis Type="Italic">Trematolobelia</Emphasis> (Campanulaceae: Lobelioideae)

Trematolobelia (Campanulaceae: Lobeliodeae) is a genus of semelparous pliestesial pachycaul rosette treelets endemic to the Hawaiian Islands. Eight species are re-cognized. The most widespread is T. macrostachys, found in the Ko‘olau Mountains of O‘ahu and on Moloka‘i and Maui. The remainder are single-island endemics: T. auriculata (Lna‘i); T. grandiflora (Hawai‘i); T. kaalae, comb. et stat. nov. (Wai‘anae Mountains of O‘ahu); T. kauaiensis (Kaua‘i); T. rockii (Moloka‘i); T. singularis (Ko‘olau Mountains of O‘ahu); and T. wimmeri (Hawai‘i).     

A monograph of <Emphasis Type="Italic">Octoknema</Emphasis> (Octoknemaceae — Olacaceae <Emphasis Type="Italic">s.l.</Emphasis>)

A revision of Octoknema Pierre is provided, based on morphological data gathered from a study of herbarium specimens and observations in the field. Fourteen species of Octoknema are recognised including six new species: O. bakossiensis Gosline & Malécot, O. belingensis Gosline & Malécot, O. chailluensis Malécot & Gosline, O. kivuensis Gosline & Malécot, O. mokoko Gosline & Malécot and O. ogoouensis Malécot & Gosline. Data are given for four additional poorly known taxa (Octoknema species A, B, C and D).     

Manifestation of salt tolerance of <Emphasis Type="Italic">Spirulina platensis</Emphasis> and <Emphasis Type="Italic">Spirulina maxima</Emphasis> cyanobacteria of the genus <Emphasis Type="Italic">Arthrospira (Spirulina)</Emphasis>

The salt tolerance of two representatives of genus Spirulina (Arthrospira) Spirulina platensis and Spirulina maxima has been investigated. They both are the wide-spread objects of photobiotechnology and it has been shown that the content of 5–15 % sea-water in medium has not caused the decreasing of biomass yield more than 15–20% as compared with control. The further decreasing of biomass was proportionate to sea-water content in medium. The investigation of reactivity of native (intravital) exometabolites secreted into cultural medium has showed that the sea-water content influence the oxidative activity (OA) of exometabolites and hour’s rhythmics.     

<Emphasis Type="Italic">Bacillus anthracis</Emphasis>, <Emphasis Type="Italic">Francisella tularensis</Emphasis> and <Emphasis Type="Italic">Yersinia pestis</Emphasis>. The most important bacterial warfare agents — <Emphasis Type="Italic">review</Emphasis>

There are three most important bacterial causative agents of serious infections that could be misused for warfare purposes: Bacillus anthracis (the causative agent of anthrax) is the most frequently mentioned one; however, Fracisella tularensis (causing tularemia) and Yersinia pestis (the causative agent of plague) are further bacterial agents enlisted by Centers for Disease Control and Prevention into the category A of potential biological weapons. This review intends to summarize basic information about these bacterial agents. Military aspects of their pathogenesis and the detection techniques suitable for field use are discussed.     

<Emphasis Type="Italic">Capparidastrum tuxtlense</Emphasis> (Capparaceae), a new Mexican endemic

We describe and illustrate Capparidastrum tuxtlense, a narrow endemic, known only from the eastern slopes of Volcán San Martín, (10–450 m), Veracruz, Mexico. Capparidastrum tuxtlense is similar to Capparidastrum discolor, but differs by foliar, floral, and fruit characters. A discussion of putative relatives and a key to the Central American species of Capparidastrum are included.     

<Emphasis Type="Italic">Boletus kermesinus</Emphasis>, a new species of <Emphasis Type="Italic">Boletus</Emphasis> section <Emphasis Type="Italic">Luridi</Emphasis> from central Honshu,Japan

Boletus kermesinus, a new species of Boletus section Luridi, is fully described and illustrated based on the materials collected in subalpine coniferous forests of central Honshu, Japan. It has distinctive features of dark-red basidiomata having distinct viscidity in the pileus surface, usually unchanging flesh, discolorous red pores, and an entirely reticulate stipe becoming coarsely lacerate-rimose with age.     

<Emphasis Type="Italic">Gagea robusta</Emphasis> (Liliaceae), a new species from <Emphasis Type="Italic">Flora Iranica</Emphasis> area

A new species, endemic to the Flora Iranica area, Gagea robusta (Liliaceae) is described and illustrated. It differs from G. reticulata (Pall.) Schult. & Schult. f. in having a puberulent indumentum on the basal leaf and from G. setifolia Baker ex Aitch. in having a long neck (up to 12 cm long). Its ecology, distribution and conservation status are discussed.     

Life cycle of <Emphasis Type="Italic">Aylax hypecoi</Emphasis> (<Emphasis Type="Italic">Insecta: Hymenoptera: Cynipidae</Emphasis>), a gall inducer on <Emphasis Type="Italic">Hypecoum</Emphasis> ssp. (<Emphasis Type="Italic">Papaveraceae</Emphasis>)

The life cycle and developmental stages of Aylax hypecoi (Trotter, 1913, Hymenoptera: Cynipidae: Aylacini) were studied in detail. Aylax hypecoi is known to induce galls in fruits of two Hypecoum species — H. imberbe and H. geslini (Papaveraceae) and the larva develops in host plant fruits. The morphology and development of egg, larva and pupa were investigated, which has previously not been done. The shape and size of terminal-instar larvae and associated galls are sex-specific. Overwintering stage, adult emergence and flying periods, and egg productivity were studied also.     

Interaction of <Emphasis Type="Italic">Bdellovibrio bacteriovorus</Emphasis> with bacteria <Emphasis Type="Italic">Campylobacter jejuni</Emphasis> and <Emphasis Type="Italic">Helicobacter pylori</Emphasis>

Interaction of Bdellovibrio bacteriovorus 100NCJB with bacteria Campylobacter jejuni (strains 1, 2, 3, 4, and 5) and Helicobacter pylori, strain TX30a, was confirmed. The results indicate that lytic activity of bdellovibrios both in liquid media and cells attached to a surface was observed. The potential use of the antimicrobial activity of predatory bacteria for environmental bioprotection and public health is discussed.
