A new species of conifer was recently discovered in northern Vietnam. In a preliminary phylogenetic analysis of morphological data a possible sister species, Chamaecyparis nootkatensis (D. Don) Spach, was identified; however, because of the presumed phylogenetic remoteness of these two species to the remainder of the Cupressaceae, a new genus-Xanthocyparis-was described to accommodate both spec...

Abnormal' cones found irt Cupressus sempervirens include bisexual cones and double female and male cones. They are very infrequent, but there are individual trees ~th a tendency· to produce· ~\Jch cones. We, suggest that these cones reflect changes in normal hohnonal balance. keY, words: Cupressus sempervirens, bisexilal con~s, cones.

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...

The heartwoods of tree species containing tropolone compounds in their extractive components are classed among the more durable woods. Two new tropolones, namely, alpha-thujaplicinol and pygmaein from the heartwood of Cupressus pygmaea, were also found to exhibit strong fungitoxic properties active against a number of wood-destroying fungi. The hydroxyl group appears to be the functional groupi...

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 eighteen taxa of Cupressus from the eastern hemisphere. The following fourteen taxa were distinct in their RAPDs: Cupressus assamica (India), C. atlantica (Morocco), C. austrotibetica (Tibet), C. cashmeriana (Bhutan), C. chengiana (Sichuan), C. darjeelingensis (India), C. duclouxiana (Yunnan), C. dupreziana (Algeria), C. funebris...

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...

BACKGROUND non-injective routes of immunotherapy in respiratory allergy have being proposed as an alternative to conventional immunotherapy. We carried out a study to evaluate the clinical efficacy and effects sublingual immunotherapy (SLIT) in patient with Cupressaceae pollen respiratory allergy. METHODS twenty patients with Cupressaceae pollen (C. sempervirens) rhinoconjunctivitis, mild ast...
