Dense Dodder on Annual Sumpweed 1811

The D.D. in the title stands for dense dodder, but you don’t have to be dense to wonder what sort of strange thing dodder is: it’s the common name for any of various species that make up the genus Cuscuta in the morning-glory family. Like better-known morning-glories, dodder is a vine, but unlike its family-mates dodder is parasitic, and that difference until recently had botanists putting dodder into a family of its own, Cuscutaceae. Dodder’s parasitic nature explains why the only greenery you see close to the ground in these tangled mounds of yellow-orange capellini (angel-hair pasta) belongs to the plants being parasitized, in this case annual sumpweed, Iva annua.

I found and photographed these plants two days ago at Meadow Lake Park on the Blackland Prairie in eastern Round Rock, where from inside my car I spotted the conspicuous dodder tangles hundreds of feet away and waded through a sea of sumpweed to take this and various other pictures.
