    Shot the catkins at random at Terra Nova, by the edge of a pond.
    Feeling strange to have 2 varieties on the same branch. Are they
    male and female ? Are they alder catkins ?

    Alnus sp..common name Alder.
    Catkins are the male flowers, they start short and tight, as season goes on the grow longer, open and release the pollen which fertilises the female parts..green cones when young .... to give the mature cones as seen in your picture.

    You have both current (2020) male and female catkins [flowers] there, and also old 2019 seed 'cones'
