WOOD ANATOMY OF THE BLAKEEAE (MELASTOMATACEAE) [PDF]

open access: yesActa Botanica Neerlandica, 1979
The present paper deals with the wood anatomy of the Blakeeae (Melastomataceae). Generic descriptions of the secondary xylem of Blakea, Topobea, and Huilaea are given and compared with data on 16 genera of the Miconieae. Numerical pattern detection was undertaken. The results confirm our preliminary ideas that Blakea and Topobea do not differ enough to

Effects of Wood Hydraulic Properties on Water Use and Productivity of Tropical Rainforest Trees

open access: yesFrontiers in Forests and Global Change, 2021
The efficiency of the water transport system in trees sets physical limits to their productivity and water use. Although the coordination of carbon assimilation and hydraulic functions has long been documented, the mutual inter-relationships between wood

Wood Anatomy of Cneoraceae: Ecology, Relationships, and Generic Definition [PDF]

open access: yes, 1988
Wood anatomy of the three species of Cneorurm is described qualitatively and quantitatively. The species differ in features related to ecology and form a clear series in this regard. The wood features of the family can all be matched by some Rutaceae and
