( Taxus ), ,
while the main weed pollens included in the data above are oil seed rape

The above calendar provides an indication of the period within which pollination
for these trees and weeds can be expected to take place. However, it should
be noted that pollination periods for each tree and weed differ greatly.
More precise data (e.g. peak pollination periods for specific trees and
weeds, etc.) can be obtained by referring to the data source for this
pollen calendar. The data
is based on the true grass family ( ).
As a person who is allergic to one type of grass is usually allergic to
most others, the above grass data is generalised.
