In this area observed copper mineralization as hypogenous
(chalcopyrite and bornite) and supergene (malachite and azurite).
The inflorescences are racemose, slender, elongated and almost globose, 7-15 cm long, sustained by a modified leaf often reduced to a terminal spathe with 70-220 zygomorphic, perfect, hypogenous
flowers (Glover & Barrett 1983).
In addition to the arrangement of the ovules in the carpels, the obvious morphological similarities between L europaea and L virginica include that both have hypogenous
flowers bearing glossy ovoid to oblong seeds ornamented with numerous tiny, polygonal cells (Spongberg, 1972; Mai, 1985; Pingen, 1996).
