Flower bud glaucescence




Glaucous (white with wax): the buds are
prominently covered with a surface white wax (e.g.
E. caesia). This condition must be assessed with
care. Because the wax is superficial, it may rub off
easily. On some parts of the tree the buds may be
green, on others they may be waxy. Obviously, if
most buds show the wax, the plant is considered to
have glaucous buds.

Glaucoma is an insidious very serious threat to vision. The test for increase intraocular pressure
used to be disagreeable, and required anaesthesia of cornea. Last one I had was just a puff of
air with special gadget that gave a direct reading, not disagreeable though a bit startling.
Should be done perhaps yearly on all middle aged patients. Such a simple way to detect serious threat.
