Artillery plant Pilea microphylla, photographed by Forest & Kim Starr.

Belongs within: Urticaceae.

The Lecantheae is a group within the Urticaceae, distinguished by the possession of a brush-like stigma. Though flowers are unisexual, female flowers retain the modified male organs as staminodes that function to eject the developing fruits upon maturity.

Characters (from Hadiah et al. 2003): Staminodes ejecting mature achenes; leaves opposite, anisophyllous to completely reduced; stipules intrapetiolar, fused; cystoliths uniformly linear.
