A Note on the Evolution of the Stamens in the Laurales, with Emphasis on the Lauraceae
Botanica Acta, 1994AbstractThe number of pollen sacs per anther and their position have traditionally been among the most important systematic characters in the Lauraceae. Opinions differ, however, about the evolutionary direction in these characters. This paper is intended to draw attention to little known morphological features of the stamens, in particular to ...

Floral Phyllotaxis and Floral Architecture in Calycanthaceae (Laurales)
International Journal of Plant Sciences, 2007Calycanthaceae are sister to the remainder of Laurales (magnoliid clade), an order seemingly showing high variability in floral phyllotaxis. Previous studies of floral phyllotaxis in this family focused on one species, Calycanthus floridus. Therefore, a comparative study of floral phyllotaxis, comprising species of all four genera of the family, was ...

A synopsis of Monimiaceae (Laurales) in the Brazilian Amazon
Nordic Journal of BotanyThis synopsis of Monimiaceae in the Brazilian Amazon provides illustrations, an identification key, the diagnosis and comments on the taxonomy and conservation status of the species. Data were collected from both physical and virtual herbaria as well as from relevant literature in order to compile information on morphological ...

Conservation Genetics Resources, 2018
Cinnamomum japonicum, belonging to family Lauraceae, is an endangered species in China. Here, the complete chloroplast (cp) genome of C. japonicum was de novo assembled using Illumina sequencing data for the first time. The whole cp genome was 152,731 bp in length, containing a pair of inverted repeat (20,092 bp for each), a large single copy (93,698 ...

Aspects of floral structure and development, and systematics in Laurales (Magnoliidae)
2008The present doctoral dissertation provides new results on the comparative floral structure in phylogenetically basal angiosperms. Five families of the order Laurales were studied: Calycanthaceae, which are sister to all other families (“core Laurales”), and Gomortegaceae, Siparunaceae, Atherospermataceae, and Monimiaceae of the core Laurales.

Journal of Biogeography, 2010
AbstractAim The biogeography of the tropical plant family Monimiaceae has long been thought to reflect the break‐up of West and East Gondwana, followed by limited transoceanic dispersal.Location Southern Hemisphere, with fossils in East and West Gondwana.Methods We use phylogenetic analysis of DNA sequences from 67 of the c.

Karyologie und �kologisch-morphologische Differenzierung vonPeumus boldus (Monimiaceae, Laurales)
Plant Systematics and Evolution, 1981The karyotype analysis ofPeumus boldus reveals a remarkable differentiation of chromosomes in size and form. C-banding pattern and interphase nuclei are discribed and compared with other genera. The great variation in leaf-shape and growth-form is continuous and correlated with the very diverse habitats of the species.

Developmental Evidence for the Convergence ofSassafras(Laurales) andHeliconia(Zingiberales) Pollen
Grana, 1987Abstract Sassafras, a dicotyledon, and Heliconia, a monocotyledon, both have inaperturate pollen grains with a highly reduced exine and thick channeled intine. This general pollen type has apparently evolved independently in at least 18 orders of angiosperms.
