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.
