The ontogeny of disparity in Cupressaceae seed cones

New Phytologist, 2023
Summary Ontogenetic shape change has long been recognized to be important in generating patterns of morphological diversity and may be especially important in plant reproductive structures.

Tropolones of cupressaceae—III.

Phytochemistry, 1967
Abstract Twenty-two samples of heartwood from various Cupressus species were analyzed by paper chromatography to determine the tropolones present. Nootkatin and β-thujaplicin seem to occur in all species. Pygmaein, α-thujaplicinol, and α-dolabrinol occur only in the three cypresses from the California coast— C. pygmea, C.

[Cupressaceae hay fever].

Allergie et immunologie, 2001
Cypress allergy or rather Cupressaceae allergy is an extraordinary observation subject and study model. Annual R.N.S.A. meeting is a good opportunity to share the analysts and sentinel doctors' point of view on this subject. For the medicine sentinel of the Nîmes's pollen site, the development of these Cupressaceae sensitivities is becoming a true ...

Biflavones of the subfamily callitroideae, cupressaceae

Phytochemistry, 1983
Abstract Twenty species, including representatives of all 11 genera of the Callitroideae, were examined for biflavonoid content of the leafy twigs. The major biflavonoids are based on amentoflavone, cupressuflavone and hinokiflavone. Their uneven distribution amongst the genera allows the distinction of five groups.

Pitting of Transfusion Tracheids in Cupressaceae

Australian Journal of Botany, 1988
The morphology and development of the circular bordered pits on the transfusion tracheids in the leaves of Callitris muelleri are described from light microscopy of semithin sections and SEM studies of cut surfaces. Two parallel bars of thickening develop on the pit border either side of the aperture, and trabecula-like outgrowths develop into the cell

Biflavones of some Cupressaceae plants

Phytochemistry, 1970
Abstract Two solvent systems, viz. toluene:pyridine:acetic acid (10:1:1) and toluene:DMF:acetic acid (10:1:1) have been found to be useful for the TLC study of biflavones in conifer extracts; these solvents have also been used for obtaining chromatographically pure biflavones and their methyl ethers by preparative TLC and “dry column” chromatography.

Biflavones of the subfamily cupressoideae, cupressaceae

Phytochemistry, 1985
Abstract Thirty species, representing all eight genera of the subfamily Cupressoideae, were examined for biflavonoid content of the leafy twigs. The major biflavonoid constituents are based on amentoflavone, cupressuflavone and hinokiflavone. The affinities suggested by biflavonyl distribution do not correlate with the currently recognized tribal ...

Distribution of the Coniferae: the Cupressaceae in Africa

Nature, 1966
THE Cupressaceae are distributed more evenly between hemispheres than any other extant family of the Coniferae. They have a high degree of generic endemism in the sense used by Good1 or of quasi-endemism. Their range, like that of most conifers, adds support to the concept that two great phytogeographical dominions existed from early geological times ...

Branching pattern in Cupressaceae

2007
In Cupressaceae, new lateral shoots are not present at each node (“continuous branching”), nor are they obviously grouped in regularly spaced tiers (“rhythmic branching”). Thus, branching pattern in Cupressaceae is referred to as "diffuse", although this does not imply that the spatial arrangement of sibling shoots along an axis is completely ...
