    Will the grass family go extinct?

    The Poaceae have existed on earth for about a hundred million years. In phylogeny, the stem age of a clade refers to the time when a group first splits from its sister lineage, and thus is considered the origin point of that group. In the case of grasses, one paper posits that this would have…

    Defining Grasses: The Remarkable and Unique Caryopsis and Embryo of Grasses

The members of the genus have attractive leaves that sometimes belie the fact that they may be invasive, although there are…

    I visited two botanical gardens last month, and perhaps the best specimens in both (at least to me!) were the bamboos. The first botanical garden was the Harry P. Leu Botanical Garden in Orlando, FL, which I have visited several times before. The second botanical garden I visited was the Kampong: A National Tropical Botanical…
