myrtleleaf St. John's-wort, Hypericum myrtifolium

Myrtleleaf St. John's-wort is distinguished by its pale clasping leaves and dichasial inflorescence.  Dichasial?  Turns out that means that each joint has two diverging branches.  Dichotomous, in other words.  But why use one word when two will confuse?  Sometimes it seems like botanists speak in tongues.  Aha, glossolalia!  But that's a word for another time and place.  This shrubby species occurs at the edges of wetlands in AL, FL, GA, LA, MS, and SC.  Taylor Co GA, 7/7/18.  St. John's-wort family, Hypericaceae.
