An entirely new type of wood that does not fit into either category of hardwood or softwood has been discovered by researchers who were undertaking an evolutionary survey of the microscopic structure ...
Insect pollination is a decisive process for the survival and evolution of angiosperm (flowering) plants and, to a lesser extent, gymnosperms (without visible flower or fruit). There is a growing ...
Trees are typically organized into two categories: hardwoods (angiosperms) and softwoods (gymnosperms). A new study suggests that there is a third type of wood—known as “midwood”—that could explain ...
A defining feature of angiosperms is double fertilization involving the female gametophyte central cell and formation of a nutrient-storing tissue called endosperm. The route for the evolutionary ...
ARGUABLY the world’s weirdest plant, Welwitschia mirabilis is a tangled mass of shredded, fraying leaves in the Namib desert. For a thousand years, perhaps more, it grows just two long leaves, which ...
High-throughput sequencing is fundamentally altering traditional phylogenetic classifications. While the Angiosperm Phylogeny Group (APG) III system based on chloroplast sequences has opened up a new ...
