Abstract: This is the fourteenth of a series of miscellaneous contributions, by various authors, where hitherto unpublished data relevant to both the Med-Checklist and the Euro+Med (or Sisyphus) projects are presented. This instalment deals with the families Apocynaceae, Compositae, Crassulaceae, Cyperaceae, Euphorbiaceae, Gramineae, Leguminosae, Nyctaginaceae, Onagraceae, Orobanchaceae, Rubiaceae, Solanaceae and Umbelliferae. It includes new country and area records and taxonomic and distributional considerations for taxa in Acalypha, Bupleurum, Carex, Datura, Epilobium, Eragrostis, Galium, Leontodon, Mirabilis, Nerium, Orobanche, Phelipanche, Rhinanthus, Saccharum, Sedum, Trifolium, Tripleurospermum and Willemetia.

Sinocrassula vietnamenis (Crassulaceae), New Species and New Generic Record in the Flora of Vietnam

New species, – Sinocrassula vietnamensis (Crassulaceae) discovered in the Northern Vietnam is described and illustrated. Standard citations of type specimens, description, name etymology, data on ecology, phenology and distribution, as well as short taxonomic remarks for the new species are provided. The species differs from its closest ally S. diversifolia in large well developed rosettes, hairy leaves, white flowers and long styles. The discovery of this species in Vietnam remarkably extends the geographical range of the genus southwards

Spatiotemporal evolution of Reaumuria (Tamaricaceae) in Central Asia: insights from molecular biogeography

Reaumuria is an arid adapted genus with a distribution center in Central Asia; its evolution and dispersal is investigated in this paper. Eighteen species of Reaumuria and nine species of two other genera in the Tamaricaceae, Tamarix and Myricaria, were sampled, and four markers ITS, rps16, psbB-psbH, and trnL-trnF were sequenced. The reconstructed phylogenetic tree is fundamentally consistent with previous morphological classification, except that R. soongorica, sometimes considered to be a separate genus or subgenus, is completely nested within Reaumuria. The ancestral area of the genus is suggested to be western Central Asia, and distributions in the Iran-Mediterranean area and the Tianshan and Pamir-Alai mountains are inferred as dispersals. Westward dispersals to the Iran-Mediterranean were ancient Oligocene to Miocene, whereas dispersals eastward were recent. The spatiotemporal evolution of Reaumuria is used as a link to abiotic paleoclimatic and geological events, in particular, increased aridity beginning at the Eocene-Oligocene Transition (EOT), and as a result of uplift of the Himalayas and Qinghai-Tibet Plateau (QTP). The diversification of the two sections (22.51-19.78 Ma) suggests a response to increasing aridification in response to QTP uplift and expansion

Molecular phylogenetic analysis and character evolution in Pseudostellaria (Caryophyllaceae) and description of a new genus, Hartmaniella, in North America

Based on sequences of ITS, matK, rbcL and rps16, a phylogenetic tree is constructed for Pseudostellaria and outgroup genera of Caryophyllaceae subfamily Alsinoideae including Stellaria and Cerastium, and members of subfamily Caryophylloideae, by means of maximum parsimony, maximum likelihood and Bayesian inference. The results indicate that core Pseudostellaria is monophyletic; however, the presence of two recognizable clades in the genus does not support the current infrageneric classification into two sections. Evolution of six morphological characters, including root tubers, stamen number and cleistogamous and chasmogamous flowers, reflect phylogenetic relationships between Pseudostellaria and allied taxa. The three North American Pseudostellaria spp. fell outside of the genus; Pseudostellaria sierrae and Pseudostellaria oxyphylla formed a well-supported clade, and they are treated as a new genus, Hartmaniella
