the essential oil obtained by hydrodistillation of flowers of calycanthus floridus l. var.oblongifolius (nutt.) d.e. boufford & s.a. spongberg, planted in sabzevar, khorasan province(iran), was analyzed by gc and gc/ms. eighteen compounds representing 90.1% of theflower oil of calycanthus floridus l. var. oblongifolius were identified, among them 1,8-cineol(33.1%), bornyl acetate (14.1%), α-pin...

Two long-standing paradigms in biology are that cells belonging to the same population exhibit little deviation from their average size and that symmetric cell division is size limited. Here, ultrastructural, morphometric and immunocytochemical analyses reveal that two Gammaproteobacteria attached to the cuticle of the marine nematodes Eubostrichus fertilis and E. dianeae reproduce by constrict...

For most angiosperms, producing and maintaining flowers is critical to sexual reproduction, yet little is known about the physiological processes involved in maintaining flowers throughout anthesis. Among extant species, flowers of the genus Calycanthus have the highest hydraulic conductance and vein densities of species measured to date, yet they can wilt by late morning under hot conditions. ...

are oppositely arranged with short petioles and are glossy green with a touch of roughness on the upper surface. In the Boston area its nodding flowers appear in mid to late spring. Appearances notwithstanding, the sepals and petals are not differentiated (therefore termed tepals): the outer tepals are a silky white with a tinge of pink and a diameter of two to three inches, while the inner tep...

The essential oil obtained by hydrodistillation of flowers of Calycanthus floridus L. var.oblongifolius (Nutt.) D.E. Boufford & S.A. Spongberg, planted in Sabzevar, Khorasan Province(Iran), was analyzed by GC and GC/MS. Eighteen compounds representing 90.1% of theflower oil of Calycanthus floridus L. var. oblongifolius were identified, among them 1,8-cineol(33.1%), bornyl acetate (14.1%), α-pin...
