80 Addisonia 



Florida, and is particulariy abundant in the Everglade region of 

 that state. In the Everglades and adjacent marshes it often grows 

 in vast patches, and in the morning the bright-colored corollas are 

 exceedingly conspicuous. 



This plant was discovered in middle Florida about the middle of 

 the last century, by A. W. Chapman, who first described it in 1860. 

 It was recorded as growing in wet pine barrens at the original 

 locality. Since the early collections were made it has been found 

 to inhabit prairies, hammocks, and particularly the Everglades. 

 Outside of the Everglades it grows in either sand or clay, but in the 

 Everglades it often grows in almost pure decayed vegetable matter. 

 There its rootstocks, enclosed in the wet spongy mass of humus, 

 absorb moisttu-e and nutriment sufficient to produce a more luxur- 

 iant growth than I have seen elsewhere. Sometimes acres are 

 covered with a growth of this showy water-willow, almost to the 

 exclusion of other vegetation. 



The specimen from which the accompanying illustration was 

 made was collected in the Everglades along the Tamiami Trail, 

 April 28, 1918, by the writer.
