Note
|
he species is here interpreted in a very broad sense, and the specimens cited show considerable variation in shape and texture of the leaves, presence or absence and nature of the foliar cystoliths, degree of pubescence, arrangement of the flowers, and size of the achenes. The American species of Urera are greatly in need of taxonomic revision.
