General Comments:

There are several different subspecies of A. glomeratus with different affinities for upland and wetland conditions.




  • A. glomeratus var. glaucopsis is notable as it has a blue-purple coloration and is almost always found in wetlands.  It is sometimes considered to be a separate species

  • A. glomeratus var. pumilus has the widest distribution in Florida and based on the relative numbers of herbarium specimens, likely the most common.

  • A. glomeratus var. hirsuitior is widespread but probably less common than var. pumilis.

  • A. glomeratus var. glomeratus has no documented herbarium specimens in the southern half of the peninsula.



Uses of the latter 3 varieties should be similar as their habitats are similar.
