The wood anatomy of the tribe Ficeae, comprising one genus, Ficus, is described. Considering the large number of species, the genus is remarkably homogeneous. It is characterised by abundant axial parenchyma in regular apotracheal concentric bands and narrow vasicentric rings, and by relatively wide vessels. On the basis of these characters, Ficus can easily be recognised within the family. .
Systematic wood anatomy of the tribe Guettardeae (Rubiaceae). The wood anatomy of nearly all genera of the Guettardeae (Rubiaceae, Guettardoideae) has been examined, and in this respect the tribe is heterogeneous. Suggestions are made for a delimitation of the tribe. Guettarda, Bobea, Antirhea, Malanea and Chomelia Jacq. are sufficiently similar in their wood anatomical characters to warrant retention in the same tribe. Machaonia, Timonius and Dichilanthe are anomalous. Suggestions are given for taxonomic revisions of some genera based on their wood anatomy.
The systematic value of this phenomenon is still uncertain. In other genera of the Melastomataceae, however, as well as in other families of the Myrtales it has also been observed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
