For those of you unfamiliar with this long lonely branch on the Angiosperm family tree, take a look at these photos. AFterwards, go find Gunnera on the angiosperm phylogeny poster at www.plantgateway.com/poster
This is a genus I fell in love with years ago after being exposed to Gunnera tinctoria at UC Berkeley, which hosts colonies of nitrogen-fixing cyanobacteria in its stems and can produce leaves up to 6 feet in diameter. The genus also produces species that are no bigger than a quarter, such as Gunnera monoica from New Zealand. Flowers in the genus can be unisexual or bisexual (check out the photos showing bisexual flowers, with an ovary topped by two styles and two stames with red anthers that have not dehisced and shed pollen yet), consisting of an ovary with two style branches and an androecium (male flower part) with two stamens. Thousands of tiny flowers will be produced on one flower spike. There are two species in the photos above, Gunnera insignis and Gunnera tinctoria. Gunnera is the only genus in the family Gunneraceae. There is only one other genus, Myrothamnus (the famed "resurrection plant" from Southern Africa and Madagascar) in the order Gunnerales.
