Thirteen species of Friesodielsia Steenis (Annonaceae) and 11 representatives related genera were included in molecular phylogenetic analyses using up to six plastid DNA regions (psbA-trnH, trnL-trnF intergenic spacers; trnL intron; matK, ndhF, rbcL exons). The results support the recognition a new species, F. lalisae Damth., Baka & Chaowasku from Narathiwat, S Thailand, as belonging one two ma...

An unknown Vincetoxicum species has recently been discovered in eastern Thailand. It is a twiner that resembles its morphology flexuosum s.l., variable taxon widely occurring from tropical Asia to Australia. Morphological examination showed despite similarities growth habit, leaf shape, gross appearance of inflorescence structure and flower colour, these two elements exhibit substantial differe...

The surface of peach (Prunus persica 'Calrico') is covered by a dense indumentum, which may serve various protective purposes. With the aim of relating structure to function, the chemical composition, morphology, and hydrophobicity of the peach skin was assessed as a model for a pubescent plant surface. Distinct physicochemical features were observed for trichomes versus isolated cuticles. Peac...

BACKGROUND AND AIMS The genus Olea (Oleaceae) includes approx. 40 taxa of evergreen shrubs and trees classified in three subgenera, Olea, Paniculatae and Tetrapilus, the first of which has two sections (Olea and Ligustroides). Olive trees (the O. europaea complex) have been the subject of intensive research, whereas little is known about the phylogenetic relationships among the other species. T...

Background – Recent collection efforts in Serra do Padre Ângelo, Pico da Aliança, and Sete Salões State Park, all located the state of Minas Gerais, have uncovered many botanical zoological novelties. The region is an outlying campos rupestres area inserted Atlantic Forest phytogeographic domain, with its flora mostly related to that core Espinhaço Range. Three species Asteraceae, one most repr...

In 1890, Salvia freyniana Bornm., an endemic species of Turkey, was first collected and described by J.F. Bornmueller in 1892. While revising the genus occurring in Turkey based on specimens collected from Yenipazar, south of Yozgat (Turkey in 1892), it was discovered once again in 2006. The diagnostic morphological characters of this rare endemic species are discussed. Details of fruiting mate...
