glaucous/smaragdine

[damoge]

While looking for information on the former, I found the latter.
They were listed as synonyms, but they are not, except to the extent that both refer to a green color.
I knew glaucous only as a seagull, and somehow always thought it had something to do with the noises they make. It is not that. It is the color. However, it is also the color of the bluish grey powdery tint of some plants. I live at the shore and we have many such here. Again, I jumped to conclusion, (so often a hard landing) that the color was in some way encouraged by the salt air.
I had never heard of the latter.
Any help with the etymology would be happily received. I got some on glaucous, but precious little on smaragdine.
(From Latin smaragdinus, from Ancient Greek σμάραγδινος (smaragdinos), from σμάραγδος (smaragdos). See emerald for more.)
I'll continue to work on the biology elsewhere.
Thanks,

The latter of the two suggestions was taken to the Doctor's office and treated here.

Glaucous is related to glaucoma, in case you were wondering.
