Monster tumbleweed: Invasive new species is here to stay

A new species of gigantic tumbleweed once predicted to go extinct is not only here to stay — it’s likely to expand its territory.  The species, Salsola ryanii, is significantly larger than either of its parent plants, which can grow up to 6 feet tall. A new study from UC Riverside supports the theory that the new tumbleweed grows more vigorously because it is a hybrid with doubled pairs of its parents’ chromosomes.
