January jewels, 2

I've seen a couple of blips of these tiny flowers recently so I thought I'd have a go.

We all recognize golden hazel catkins dancing in the wind, shedding their pollen in the air. Those  prolific danglers are male. (Each catkin is actually a collection of about 250 individual flowers.) 

Less easy to spot are these female flowers which look like tiny pink sea anemones with tentacles (styles) just a few millimetres long. Each one sits atop a fat bud which contains the rest of the flower, and where the nuts (up to 4 on each cluster) will be produced. 
But, to avoid self-fertilization, the hazel tree lets its male catkins bloom first and spread their pollen to the breezes. When that's done the female flowers open and wait to catch some air-borne pollen from another hazel.

In the first image you can see the flower atop the big bud which acts as a sort of womb,  and in the second the tiny pink star is gleaming through a cluster of lichen with which this tree was festooned.
