New distributional and molecular information call into question the systematic position of the West Asian Viola sintenisii (Violaceae)

The west Asian Viola sintenisii W.Becker, described from temperate woodlands of northern Iran and south-western Turkmenistan on the Caspian coast, was long considered a vicariant geographical subspecies of the mainly south European V. alba Besser. The new findings of V. sintenisii in four geographically separated stations in north-eastern Azerbaijan significantly expands its range of distribution. These occurrences are within the range of V. alba ssp. alba . Here the two taxa frequently co-occur but remain distinct and V. sintenisii is therefore justified at species level. It is likely that the two species are also sympatric in the Hyrcanian region, a range previously attributed uniquely to the latter. Viola sintenisii seems to be fairly common in the eastern parts of the Great Caucasus, but there are reasons to suggest that it has there been misinterpreted as V. suavis . The chromosome number of V. sintenisii , 2 n  = 20, is reported here for the first time.  © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society , 2005, 147 , 91–98.     

A new violet species (Violaceae) from the south-west Alps

Viola laricicola Marcussen sp. nov. is described from collections from four French and Italian localities in the south-west Alps. It is closely related to V. riviniana (section Trigonocarpea ) but differs in a few morphological characters and by the chromosome number 2 n  = 20. Viola laricicola is endemic to the montane and subalpine coniferous forests in the continental parts of the Alps.  © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 142 , 119–123.     

A new species of Selaginella from Hainan Island, China, with a key to the Hainan species

Diagnostic notes and a key to the species distributed in Hainan are also provided.  © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society , 2005, 148 , 323–327.     

A new species of Viola (Violaceae) from south-west Turkey

Viola dirimliensis Blaxland is described as a new annual species from south-west Turkey, belonging to section Melanium Gingins. It was found growing only on serpentinite, in two adjacent locations in Mula vilayet, west of Antalya, at altitudes of 1500–1690 m. The locations were typical serpentinite barrens, almost bare of vegetation, with some plants of Muscari macrocarpum , and a few trees of Pinus nigra var. caramanica . The Viola is named after the type location, the Dermil Pass or Dirimli Geçidi, where the tiny plants were growing between the rocks on south-facing slopes. Their distinct golden-yellow flowers are unlike any of the other small annual Viola species found in Turkey.  © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 145 , 505–509.     

Studies on Thapsia (Apiaceae) from north-western Africa: a forgotten and a new species

A new species of Viola (Violaceae) from Turkey

A new species of Viola , V. kizildaghensis M. Dinç & S¸. Ẏlḋṙml̇, from Turkey is described and illustrated. It is found on the rocky slopes of K̇żldǎ, K̇żldǎ National Park, in the vilayet of Isparta, south-west Turkey, at an elevation of 1350–1600 m. It belongs to Viola , subsection Viola , and is similar to the Lebanese endemic V. libanotica Boiss., distinguished by its lanceolate, cuneate based leaves, pinkish-purple flowers with white throats, glabrous lateral petals, and peduncles bearing the mature fruit procumbent and pubescent. It is somewhat similar to another species from south-west Turkey, V. sandrasea Melchior, that is endemic to Sandras Dǎ in the vilayet Mǔla; it is distinguished from this by the characters listed above, its pubescent leaves and peduncles, and its linear-lanceolate to lanceolate stipules which have short, gland-tipped fimbriae. © 2002 The Linnean Society of London, Botanical Journal of the Linnean Society , 2002, 138 , 483–487.     

A new Coryphoid palm genus from Madagascar

Tahina J.Dransf. & Rakotoarinivo, gen. nov. (Arecaceae) is described as a new genus from north-western Madagascar, with a single species T. spectabilis J.Dransf. & Rakotoarinivo, sp. nov. Tahina is included within tribe Chuniophoeniceae of subfamily Coryphoideae, based on the strictly tubular imbricate rachilla bracts, the flowers grouped in cincinni with tubular bracteoles, and the stalk-like base to the corolla. This position is corroborated by evidence from plastid DNA. Lamina anatomy is discussed in detail, and similarities with and differences from the other members of Chuniophoeniceae are discussed. Based on the ecological characteristics of the single locality, predictions are made on where else it may occur in Madagascar.  © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 156 , 79–91.

A new species of Halisaurus from the Late Cretaceous phosphates of Morocco, and the phylogenetical relationships of the Halisaurinae (Squamata: Mosasauridae)

A new species of the basal mosasaurid Halisaurus from the Late Cretaceous (Late Maastrichtian) of the Oulad Abdoun Phosphate Basin of Morocco is described on the basis of both cranial and postcranial remains. H. arambourgi sp. nov. is characterized by unique features of the nares, frontal, parietal, girdle and limb bones. A phylogenetical analysis supports the monophyletic status of Halisaurus ; H. platyspondylus (Maastrichtian, New Jersey), H. ortliebi (Maastrichtian, Belgium) and H. arambourgi form an unresolved polytomy. This study does not support the attribution of ' Halisaurus ' sternbergii (Santonian, Kansas) to Halisaurus nor to any known genus. A new genus, Eonatator , is proposed for the reception of this species, Eonatator sternbergii comb. nov. The new taxon Halisaurinae ( Halisaurus  +  Eonatator ) is the sister-group of more advanced mosasaurids (Natantia). Halisaurines are defined by the shape of the lateral premaxilla–maxilla suture; an oblique contact plane between the parietal and the supratemporal; a preaxial ridge present on the distal two-thirds of the radius length; and tibia and fibula long and slender with slightly expanded extremities.  © 2005 The Linnean Society of London, Zoological Journal of the Linnean Society , 2005, 143 , 447–472.     

A new species of Acantholimon Boiss. sect. Glumaria Boiss. (Plumbaginaceae) from Elazığ, Turkey

The species grows on alpine steppe and stony places in Bozkır (C4 Konya province) in South Anatolia. It is closely related to O. nutans L. and O. demirizianum Malyer & M.Koyuncu, an endemic confined to South Anatolia. Diagnostic morphological characters are discussed. Notes are also presented on the ecology, biogeography and conservation status of the new species.  © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society , 2005, 148 , 501–504.     

A new species of Achillea (Asteraceae: Anthemideae) from south-east Peloponnisos, Greece

A new species of Achillea L., Achillea occulta Constantin. & Kalpoutz., from the summit area of Mount Koulochera in south-east Peloponnisos, Greece, is described and illustrated. It belongs to A . sect. Ptarmica and further, to a small group of taxa known under the illegitimate sectional name 'Anthemoideae'. In Greece, A. occulta has no close allies. The taxonomically related taxa, i.e. A. barrelieri (Ten.) Sch. Bip., A. mucronulata Bertol., A. oxyloba (DC.) Sch. Bip. and A. schurii Sch. Bip. are found in the Italian Peninsula, the Alps and the Carpathians. Phytogeographically, the finding of a species with such taxonomic connections in south-east Greece was unexpected. The new species grows in semi-shade, often hidden in suitable limestone rock hollows and the foot of rocks, together with several other Greek endemics. Its chromosome number of 2 n  = 18, counted in root tips, is also reported and illustrated.  © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society , 2005, 147 , 249–256.     

Bauhinia larsenii, a fossil legume from Guangxi, China

Fossil leaves and a branch with a leaf and a pod attached have been discovered from Ningming County, Guangxi Autonomous Region, China, and are described as Bauhinia larsenii sp. nov. (Leguminosae: Cercideae). The strata from which the Bauhinia fossils were collected, namely the Ningming Formation, were dated as Late Eocene–Oligocene based on a combination of pollen, fauna and flora. The affinity of the new species to Bauhinia section Micralvesia subsection Viridescentes species is also discussed.  © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society , 2005, 147 , 437–440.
