A new species of Carex sect. Rhomboidales, C. jianfengensis, is described and illustrated from Hainan, China. The new species is similar to C. zunyiensis but differs in having involucral bracts sparsely hispid and with ca.1 cm long sheaths; inflorescence with 4 spikes, terminal spike ca. 2.5 cm long, lateral spikes 2-3.5 × 0.7-1 cm; staminate glumes narrowly ovate, ca. 5 mm; pistillate glumes t...

Ophryotrocha shieldsi, sp. nov. is described from Macquarie Harbour, Tasmania, Australia, where it occurs in high densities beneath the sea cages of fish farms. SCUBA and ROV underwater observations revealed closely spaced mounds of aggregations of the new species. It is closely related to O. lobifera Oug, a species reported from fish farms and whale-falls in the North Sea, from which it can be...

A new species of Lepanthes from southwestern Colombia is presented here. farallonensis belongs to the informal group “manabina”, which comprises with concave and commonly pubescent leaves, flowers resting at adaxial side synsepal short long tails. similar L. smaragdina in broadly ovate dorsal sepal but differs conspicuously twisted upper lobes petals, outwardly bent a depression center laminae ...

The organization of living cells is based on networks of interacting molecules. Systematic analysis of protein interactions of 3-aa loop extension (TALE) homeodomain proteins, fundamental regulators of plant meristem function and leaf development, revealed a highly connected, complex network. The network includes nine members of Arabidopsis thaliana ovate family proteins (AtOFPs), a plant-speci...

Albizia, a diverse tree genus, occupies monsoonal warm humid rain forests in tropical and subtropical regions. We recovered well-preserved compound fossil leaf two fruits of Albizia (Fabaceae) from the latest Neogene (Rajdanda Formation: Pliocene) sediments Jharkhand Chotanagpur Plateau, eastern India. On basis architectural features leaf, new species is established as A. mahuadanrensis Hazra, ...

The cytology of teliospore germination and basidiospore formation in Urornyces appendiculatus vat. appendieulatus was characterized with light and fluoroscence microscopy. Meiosis of the diploid nucleus occurred in the metabasidium. The four haploid daughter nuclei migrated into the basidiospore initials where they underwent a post meiotic mitosis. Each basidiospore was delimited from the meata...

A new species of Trichodoridae, Trichodorus elefjohnsoni, is described from undisturbed regions of Great Smoky Mountains National Park, United States. It resembles T. orientalis De Waele &Hashim, 1984, T. persicus De Waele &Sturhan, 1987, and T. taylori De Waele, Mancini, Roca, ' Lamberti, 1982 in arrangement of ventromedian cervical papillae and posterior preanal supplements, but differs by co...
