Bickxell: SruniEs i\ Sisvri.nciiium 



■ The fcw-sccdcd capsules are suggestive of 5. dichoiomum to 

 ^vh.ch, in other respects, the species seems to be related, but not 

 so closely as to need detailed comparison. 



The above description of the species has been considerably 

 modified to accommodate the collection cited from Silver Creek 

 Georgia. represented by a very full sheet of specimens. These 

 d.ffer from all the others in serrulate edges of stem and leaf, more 

 slender peduncles uniformly much surpassing the bracteal leaves 

 rather broader and straighter spathes of less attenuate subequal 

 bracts, the outer one less united clasping, the inner one mostly ab- 

 ruptly pomted from a scarious tip. It is quite possible that this 

 plant merits se])arate recognition.
