Discussion

Species 2 (1 in the flora).

The species of Pentalinon have previously been treated as members of Urechites Müll. Arg., but B. F. Hansen and R. P. Wunderlin (1986) have convincingly argued that Pentalinon is legitimate and should be used instead of the more familiar, but later, Urechites.
