Calliandra (Leguminosae) in continental Africa

The mainly neotropical genus Calliandra Benth. (Leguminosae–Mimosoideae–Ingeae) is reported for the first time as native in continental Africa. There are two species known, C. gilbertii Thulin & Hunde sp. nov. in E Kenya and Somalia and C. redacta (J. H. Ross) Thulin & Hunde comb. nov. in South Africa near the Namibia border. On pollen morphological grounds they are supposed to be most related to certain neotropical species but the pollen does not agree entirely with any previously known group of the genus. The distribution of C gilbertii and C. redacta stresses the phytogeographical link between the arid zones of northern and southern Africa.     

Mollugo viscosa sp. nov. (Molluginaceae), a segregate of M. brasiliensis from Minas Gerais in eastern Brazil

The new species Mollugo viscosa Thulin & Harley is described from Minas Gerais in eastern Brazil. It was previously part of the recently published M. brasiliensis Thulin & Harley, a species that was found to be non‐monophyletic in molecular phylogenetic analyses. Mollugo brasiliensis is here divided into a northern species (M. brasiliensis s.str.) in Bahia and a southern species (M. viscosa sp. nov.) in Minas Gerais. The new species differs from M. brasiliensis in its denser and more viscous indumentum, and in its distinctly smaller seeds with smaller tubercles and a smaller hilar peg, and from its sister species M. ulei by being a perennial herb with bisexual flowers.

ESSENTIAL OILS AS TAXONOMIC AIDS IN THE CLASSIFICATION OF DICHANTHIUM PARVIFLORUM

Essential oil components and gross morphological characters are closely correlated in Dichanthium parviflorum (R. Br.) de Wet et Harlan (Gramineae) and related species. Different species, varieties, and geographical races, as well as hybrids between them, can be identified on the basis of absence or presence and quantity of essential oil components. The morphologically variable D. parviflorum was subdivided into four varieties: var. parviflorum, var. capilliflorum (Steud.) de Wet et Harlan comb. nov., var. mutispiculum (Ohwi) de Wet et Harlan comb. nov., and var. spicigerum (S. T. Blake) de Wet et Harlan comb. nov. These varieties differ from each other morphologically in having respectively racemes with 1-4 and awned, 3-5 and awned, 1-2 and awnlass, and 4-10 and awned spikelet pairs per raceme.

Productivity and respiration of three seagrass species from the gulf of Aqaba (Jordan) and some related factors

Net productivity and rates of respiration of the seagrasses Halodule uninervis (Forsk.) Aschers., Halophila ovalis (R. Brown) Hooker fil. and Halophila stipulacea (Forsk.) Aschers., from Aqaba (Jordan) are presented in this paper. The effect of some physical and chemical parameters on the productivity of H. stipulacea is discussed in some detail. Of the three species, H. stipulacea is considered a shade plant since it is photoinhibited at light intensities near 100 Wm^?2 and has a productivity/respiration ratio of 1.8 at 30 m depth.     

Phylogenetic studies of the subgenus Nialoe (s. lat.) (Coleoptera, Carabidae, Genus Pterostichus), part 2: The Asymmetricus species group

Pterostichus (Nialoe) asymmetricus Bates and its allies are revised based on the membranous parts of their genitalia. Four new taxa, P. (N.) ovaliphallus sp. nov., P. (N.) fujimurai ibukiyamanus ssp. nov., P. (N.) shotaroi kiimontanus ssp. nov., and P. (N.) basilobatus sp. nov. are described. A cladistic analysis based on 31 morphological characters reveals that Daisenilaoe (s. str.) Nakane and Straneo is included as one clade within Nialoe (s. str.). The speciation and dispersal process of this species group are also discussed.     

New species of Neotibilis Grazia & Barcellos (Hemiptera: Pentatomidae: Pentatomini)

Three new species of Neotibilis Grazia & Barcellos are described from Brazilian Amazon region and Ecuador, based on general and genital morphology: Neotibilis (Neotibilis) claviformis sp. nov., Neotibilis (Neotibilis) ecuadorensis sp. nov. and Neotibilis (Neotibilis) manauara sp. nov. Illustrations and a key to species of the type subgenus are given. The range of Neotibilis is expanded, with new records for N. (N.) biguttata (Walker)--Brazil (Amazonas) and N. (N.) chiapensis (Thomas & Brailovsky)--Brazil (Roraima and Pará).     

Phylogenetic relationships among species ofWilliopsis andSaturnospora gen. nov. as determined from partial rRNA sequences

Phylogenetic relationships among those yeast species that form saturn-shaped ascospores and which are assigned to the generaWilliopsis andPichia were estimated from their extent of nucleotide sequence divergence in three regions of ribosomal RNA. ThePichia species (P. dispora, P. saitoi, P. zaruensis andP. sp. nov.) are a closely clustered group only distantly related toWilliopsis, and it is proposed that they be reassigned toSaturnospora gen. nov. The extent of divergence amongWilliopsis species (W. californica, W. mucosa, W. pratensis, W. saturnus andW. sp. nov.) is greater than that previously observed within other ascomycetous yeast genera.

Verbascum eskisehirensis sp. nov. (Scrophulariaceae) from central Anatolia, Turkey

Verbascum eskisehirensis Karavel., Ocak & Ekici sp. nov. (sect. Bothrosperma Murb.) is described and illustrated from Turkey. This new species is confined to B3 Eskisehir in central Anatolia. A morphological comparison is made with the closely related species; V. oreophilum K. Koch and V. pyramidatum M. Bieb. In addition, a cluster analysis was conducted and a distribution map of the new species and the related species is also given.     

Comparison of cell wall compositions of the rhizomes of three seagrasses

Cell walls from rhizomes of Halophila ovalis (R. Br.) Hook.f., Halophila stipulacea (Forsk.) Aschers. and Halodule univervis (Forsk.) Aschers. were analysed. The non-cellulosic polysaccharides contained glucose as the most abundant sugar and arabinose as the next most abundant sugar in all cases. Only small amounts of pectin were found. Halodule uninervis differed from the two Halophila species in its large amount of cell wall material per gram fresh weight and in its high proportion of non-cellulosic polysaccharides. The lignin from all three plants contained non-conjugated phenols, with relatively few conjugated phenols.
