yaupon blacksenna, Seymeria cassioides
Yaupon blacksenna is an annual parasite on the roots of several species of pine. It can be a meter tall, with flowers about a centimeter across. Each flower lasts but one day. The winged seeds are wind dispersed. It can form large patches after fire or other disturbance, so it's a significant pest in pine plantations. In a preserve like the one where this one grew there is not much disturbance, and plants were dispersed. They added a nice fall accent. This grows in AL, AR, FL, GA, LA, MS, NC, SC, TN(X), TX, and VA. Doerun Pitcher Plant Preserve, Colquit Co GA, 10/19/15.
