Muhl Cat. p. 86. Nutt. 2. p. 213, 



A plant very similar in most respects to the preceding, but with the stem 

 and leaves pubescent, and the bracteal leaves and calyx very pubescent. 

 As far as it has fallen under my observation, it appears to bear smaller 

 leaves, longer in proportion to their size, and the lobes less divaricate; and 

 the bracteal leaves which in the former species are with us ovate and acute, 

 are in this shorter, nearly round, and obtuse. 



Grows very common in the western districts of Georgia. I do not re- 

 member to have seen it along the sea coast. 



Flowers August — October.
