Platanaceae

Platanus*

Platanus*

This family has only one genus and nine species, distributed throughout warm zones. Its allergological importance comes from its use as an ornamental tree along avenues and boulevards.

In Spain, the most important is the Plane tree(Platanus hispanicus) and it is mainly located in the urban environments.

Plane tree pollen is small-medium sized (16-25 µm in diameter), spheroidal, and with a somewhat reticulated surface.

Its pollinization is explosive in early Spring, between March and April, with peaks that can exceed 2,000 grains of pollen/m3 of air).
