    Comparative fruit studies in a group of tribe Peucedaneae (Umbelliferae)
    (Laser Pages Publ Ltd, 2001) Menemen, Y.; Jury, S.L.
    Comparative fruit studies (macro- and micro-morphology and anatomy) have been undertaken in a group of tribe Peucedaneae (Umbelliferae) (Malabaila Hoffm., Pastinaca L., Heracleum L., Stenotaenia Boiss., Opopanax W.D.J. Koch, and Grafia Rchb.). A multivariate analysis was carried out using Simple Matching Coefficient and UPGMA (unweighted pair group method using arithmetic averages) and WPGMA (weighted pair group method using arithmetic averages) clustering methods. Two types of dorsal mericarp, surface and margin sufaces were detected: (1) reticulate with a smooth surface, (2) reticulate with a striate surface. On the dorsal surface of the mericarps, three hair shapes and four hair surface types were seen. These hairs are treated as having systematic significance. For instance, a very short triangular hair with a papillose surface is unique to Pastinaca. The shapes of the mericarp and mericarp apex at the base of stylopodium are significant features for generic delimitation. Malabaila is distinguished by its cordate-obovate mericarp with mericarp apex curved at stylopodium base. Anatomical features, such as the number of the vittae on the dorsal surface, the length of the mericarp wing neck and margin, are significant. The genera Stenotaenia and Opopanax are characterized by having many vittae on the dorsal and commissural. surfaces.

    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.

    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.
