On a trip to the ocean, I wade through a thick reddish-green mat of rubbery plants to get to the beach. The ankle-high leaves are spiky and break off under my feet with a crunch. Large yellow flowers are scattered across this green carpet, each with hundreds of skinny petals surrounding a nest of pollen-dusted stamens. This is Carpobrotus edulis, one of several kinds of iceplant in the area. None are native.
The fruit of Carpobrotus edulis, as its name suggests, was traditionally eaten back in its original territory of South Africa. It was deliberately brought to California, planted to bind coastal soils together and help stop erosion. It does seem to be successful at that job – you can see it growing on beaches and even in colorful tapestries drooping over the edge of cliffs. However, it’s another good intention gone wrong since it has turned out to be highly invasive; an “ecological bulldozer,” along the lines of broom, that wreaks havoc on the delicate dune ecosystem. All the species of ice plant look at least somewhat similar, though not all of them are closely related (there are five species in four different genera, with the two types of Carpobrotus being the most common around here, as far as I can tell).

Hello Jacob, Enjoyed reading your blog (got to it through your post on Jake Sigg’s site). Since you’ll likely be writing a good deal and needing
to use the plural of “genus” often I pasted below a dictionary entry:
What is the plural for genus: “genuses” or “genera”? Are they both correct?
The plural of the word genus is genera, according to the Longman Advanced American Dictionary (Longman, 2000), the Longman Grammar of Spoken and Written English (Longman, 1999), The American Heritage Dictionary of the English Language (Houghton Mifflin, 1996), Webster’s New Twentieth Century Dictionary (Collins World, 1977), and the Collins COBUILD English Dictionary (HarperCollins, 1995).
Thanks Vishnu! Correction made. I knew that once upon a time and am grateful for the reminder 🙂
Oh – for the record – it’s Jacoba not Jacob.
