Unknown Flower

I am wondering if anyone can identify this plant for me.  It is a flowering evergreen, thorny bush that grows quite tall >6 ft.  In the spring it has clusters of these very tiny yellow flowers. Each little flower is about 1/8 inch in diameter (4mm) and they are quit fragrant. From a distance, one hardly notices the flowers.  The thorns are nearly lethal at about 1 1/4 inch long (~3 cm).  I have tried internet searching for an ID but failed.

I left a thorn or two in the image so you can see them.  I didn’t include the one with blood on it as a result of the injury I sustained while getting this shot. It is amazing the lengths we will go to for a blip. Who knew Flower Friday could be dangerous?

Cheers to the weekend!
