*' This is sometimes called 'sprouting Craljgrass.' The stems 

 are at first erect, then become decumbent and spreading, frequently 

 attaining a length of G-7 feet, bent and rooting at the lower joints. 

 It has much the same habit as P. Texanum, but the stems are 

 smooth and more flattened; the leaves also are smoother and 

 larger. The stems are sometimes nearly an inch thick at the base, 

 and very succulent. Tlie panicles are sometimes 2 feet long."
