Phylogenetic comparisons of three nuclear DNA gene regions (nrDNA(ITS), 4-coumarate: CoA ligase, abscisic acid-insensitive 3) and a chloroplast region (petN-psbM) show that the Western Hemisphere cypresses (Hesperocyparis) is a well-supported clade quite separated from the Eastern Hemisphere cypresses (Cupressus). Based on these new data and previous data, a new genus, Hesperocyparis, is erecte...

Belowground processes are rarely considered in comparison studies of native verses invasive species. We examined relationships between belowground fine root production and lifespan, leaf phenology, and seasonal nitrogen dynamics of Lonicera japonica (non-native) versus L. sempervirens (native) and Frangula alnus (non-native) versus Rhamnus alnifolia (native), over time. First and second order f...

UNLABELLED Allergen immunotherapy dates back to 1911 and has been used successfully to treat large numbers of patients throughout the last century. CASE REPORT a 66-year-old woman presented with symptoms of allergic rhinitis and asthma due to sensitization to Cupressus arizonica. Specific immunotherapy was prescribed as a continuous 2-year treatment with a depot preparation of standarized and...

BACKGROUND AND AIMS Hydration, rupture and exine opening due to the sudden and large expansion of intine are typical of taxoid-type pollen grains. A hemispheric outgrowth external to the exine was observed on Cupressus and Juniperus pollen grains before the intine swelling and exine release. However, the actual existence of this permanent or temporary structure and its precise role in pollen hy...

Random amplified polymorphic DNAs (RAPDs) data were analyzed from all the taxa of Cupressus from the western hemisphere. Populations of Cupressus from Arizona and Texas, USA, were found to cluster in the two groups delimited by Wolf (1948): C. arizonica and C. glabra. These data suggest that these taxa might be better recognized at the specific level as per Wolf (1948), rather than at the varie...
