Lechea divaricata
Some individuals of Lechea stricta can be difficult to determine with certainty; the extremes of variation of L. stricta often grade into that of L. intermedia and L. pulchella.

Of conservation concern.
Lechea divaricata is endemic to peninsular Florida but apparently absent from the Florida Keys. A report of L. divaricata from Alabama was based on a misidentified specimen of L. mucronata (D. D. Spaulding 2013).
