Ketenoglu & Y. Menemen (Fabaceae), a new species from Turkey is described and illustrated. It belongs to section Hypoglottoidei DC. and resembles A. viciifolius DC. and A. viridissimus Freyn & Sint., from which it differs in the habit, indumentum of stem and leaf, and floral features.Öğe Flavonoid patterns in Convolvulus L., (Convolvulaceae) species from Morocco(Pakistan Botanical Soc, 2002) Menemen, Y.; Williams, C.A.; Jury, S.L.This study was undertaken to document the distribution of chemical components and determine whether phytochemical characters support the delimitation of the taxa in the genus Convolvulus L., from Morocco. Twenty taxa from the genus were investigated for their flavonoid aglycone constituents. The flavonols quercetin, kaempferol and isorhamnetin, the flavone luteolin and the hydroxycoumarin cichoriin were identified. It was seen that the aglycone pattern is useful for the delimitation of some species in the genus and correlate with morphological features. The flavonoid glycosides identified from Convolvulus mazicum were isorhamnetin 3-glucoside, quercetin 3-glucoside and 3-galactoside and luteolin 5-glucoside.Öğe ITS DNA sequence utility for the relationship of Heracleum L. (umbelliferae) genus(Blackwell Publishing, 2006) Maras, M.; Aksöz, E.; Menemen, Y.; Hamzaoğlu, E.…Öğe Linaria dumanii (Scrophulariaceae), a new species from south Anatolia, Turkey(Finnish Zoological Botanical Publishing Board, 2002) Duran, A.; Menemen, Y.Linaria dumanii A.

It is closely related to S. caramanica Boiss. & Heldr., from which it differs mainly in its habit, hairiness, leaf and floral features. (C) 2003 The Linnean Society of London.Öğe A taxonomic revision of the genus Pastinaca L. (Umbelliferae)(Laser Pages Publ Ltd, 2001) Menemen, Y.; Jury, S.L.A taxonomic revision of the genus Pastinaca L. was carried out with respect to fruit macro- and micro-morphology, anatomy, palynology, and phytochemistry. The study covers the world distribution of the genus, confined to Europe and Asia, except for Pastinaca sativa L. subsp. sativa (parsnip) cultivated all over the world. Pollen studies showed that the pollen of the genus could be described as cerebroid. Three flavonoid compounds were detected in the: genus. Pastinaca is represented with eight species and four subspecies in the world. P. latifolia DC. is regarded as a subspecies of P. sativa.
