Ecology : This is an extremely deep shade tolerant species commonly found in high forest in the lower to mid-canopy (Sunderland, 2012). L. opacum prefers well-drained soils.
  This species can sometimes be confused with L. laeve, from which it can be easily distinguished by the presence of armed leaflet margins.
