Boggy and swarapy places, and often partly floating in shallow 



water. 2^. 6— 8.— A highly variable plant, depending much for 



Its appearance on soil and situation. In rather dry places it often 



rises erect, 3_4 inches higli, having a bulbous or swollen base, and 



is then the orignial J. lulbosus L. At other times the steras are 



spreading or procumbent, when it becomes the J. rnhverticil'mtus of 



W ulfen. Again, these procumbent stems often take root at intervals, 



and are proliferous; or, vyhen growing in water, they float upon 



the surface and spread their long flaccid branches in all directions. 



1 he ramifications and panicles are exceedingly irregular; the latter 



iew-flowered. _ It is often extremely difficult to distinguish this 



Jrora small varieties of /. lamprucarpns.
