Studies on generaMallomonas andSynura,and other plankton in freshwater with the electron microscope

A new genusSpiniferomonas of the Synuraceae was established withSpiniferomonas bourrellii as the type species. The cells ofSpiniferomonas are solitary, freeswimming, biflagellated, and covered with siliceous scales and spines. The genus shows a similarity to theChrysosphaerella (Synuraceae) in the structure of scales and spines. In addition to the type species, six species were also described as the new taxa of this genus. They were named asS. abei, S. bilacunosa, S. trioralis, S. crucigera, S. conica, andS. alata, respectively. All the specimens were collected from ponds and lakes in Japan.S. trioralis was also collected from the Republic of South Africa.

A new species of the cardinalfish genus Gymnapogon (Perciformes, Apogonidae) from the Red Sea

 A new cardinalfish species, Gymnapogon melanogaster, is described from two specimens collected at night in the Gulf of Aqaba, Eilat, Israel. This species is characterized by having 9 dorsal and 8 anal fin soft rays; 14–15 pectoral fin rays; 2 + 11 gill rakers; a flat, bifurcated preopercular spine; a naked body without a papillae network; black pelvic fins; and a black stomach. It is similar to Gymnapogon vanderbilti (Fowler, 1938) that is known only from the Line Islands of the Central Pacific Ocean.

Morphological redescription and neotype designation of Sulcospira paludiformis (Yen, 1939) from Hainan,China

Semisulcospira paludiformis, collected from Hainan Island, China, was described by Yen in 1939. While the type specimens of S. paludiformis were destroyed in World War II, the systematic classification of this species has remained dubious because of the lack of further study. In 2015 we collected fresh specimens from near the type locality, based on which we have described the morphology and have designated a neotype. The anatomy shows that the species belongs to the genus Sulcospira Troschel, 1858 (family Pachychilidae).     

New Observations on the Ciliate Genus Vestibulongum (Pycnotrichidae): Vestibular Ultrastructure,Macronuclear Endosymbiotic Bacteria,Biogeography, and Evidence for Host Specificity

Two isolates of the pycnotrichid ciliate genus, Vestibulongum, were collected from the host fish, Acanthurus xanthopterus, from two locations in the Southern Pacific Ocean. One was from the Great Barrier Reef (GBR), and a second from Papua New Guinea. These sites are thousands of km from the type locality, off the coast of South Africa. New data were collected from protargol‐stained samples to more fully characterize the general form and light microscopic structures of the ciliate. Specimens from all three sites had a long vestibule, characteristic of most members of the family. Data suggest that specimens from each site are the same genus. The kinetids of the Vestibulongum isolated from the GBR contained the typical components of postciliary, transverse, and nemodesmatal microtubules, and Kd fibrils. Also, two quite different forms of endomacronuclear bacteria were observed and are described. One of those has distinct endospores, which are similar to endospores in nuclear endosymbiotic bacteria in a species of Balantidium from the gut of another species of surgeonfish.

Dr Patrick Neill's herbarium of Scottish garden plants in the National Botanic Gardens,Glasnevin, Dublin (DBN)

Summary

Specimens (ex herb. William McNab) collected by Dr Patrick Neill (1776–1851), of Canonmills, Edinburgh, in his own garden and other Scottish gardens (including the Botanic Garden, Edinburgh), c. 1799–1805, are noted and catalogued. Some represent horticultural hybrids of local origin, and a few specimens originated from seeds captured from French naturalists during the Napoleonic Wars.     

A revision of the genus Cryptonemia (Halymeniaceae,Rhodophyta) in Bermuda,western Atlantic Ocean,including five new species and C. bermudensis (Collins & M. Howe) comb. nov.

Cryptonemia specimens collected in Bermuda over the past two decades were analysed using gene sequences encoding the large subunit of the nuclear ribosomal DNA and the large subunit of RuBisCO as genetic markers to elucidate their phylogenetic positions. They were additionally subjected to morphological assessment and compared with historical collections from the islands. Six species are presently found in the flora including C. bermudensis comb. nov., based on Halymenia bermudensis, and the following five new species: C. abyssalis, C. antricola, C. atrocostalis, C. lacunicola and C. perparva. Of the eight species known in the western Atlantic flora prior to this study, none is found in Bermuda. Specimens reported in the islands in the 1900s attributed to C. crenulata and C. luxurians are representative of the new species, C. antricola and C. atrocostalis, respectively.     

Manihot gratiosa and M. lourdesii spp. nov. (Manihoteae,Euphorbiaceae) from the Brazilian Cerrado

During a botanic expedition in 2013 to study the taxonomy of the genus Manihot in the Cerrado biome, numerous specimens were collected in the Chapada dos Veadeiros region, in central Brazil. After careful analyses, two new species of this genus were discovered. Manihot gratiosa and M. lourdesii are herein described and illustrated. Both species can be distinguished from morphologically similar species by a combination of characters such as shape and overlapping of leaf lobes, indumentum, type and aspect of inflorescence, integrity of pistillate sepals, as well as shape, integrity, and size of bracts of both male and female flowers.     

Thomas J. Booth and the type localities of his Indian rhododendrons described by Nuttall

Summary

The new species of Rhododendron described by Thomas Nuttall in 1853 from specimens collected by his nephew Thomas Jonas Booth (b. 1829) and then recorded from ‘Bootan’ (Bhutan), where Booth did no collecting except possibly in the Meru Mts, came from northern Assam. All of Booth's collecting appears to have been done in the Balipara Frontier Tract and in the Aka and Daphla Hills, which have never during the past two and half centuries formed part of Bhutan. The belief that Booth collected in Bhutan seems due to a loose application of the term ‘Bhutan Himalaya’ to include tribal territory east of the 92nd meridian.     

Index to the vascular plant types collected by H. H. Smith near Santa Marta,Colombia

An index to 360 names based on specimens collected from 1898 to 1901 by H. H. Smith in Santa Marta, Colombia is provided.

Additional comments are provided to clarify the type status of specimens representing a single taxon and given a single collection number but collected on several different dates or from several different localities, and for truly mixed collections where two or more taxa were given the same number.
