It hurt to dig this one out and throw it in the trash. Not because it was big and heavy, though it was nearly 36" (90 cm) wide, but because it was really beautiful. From the front. On the back, however...
This is Aloe gall mite (link--and go all the way to the bottom of the page past the fried steak ad and read the discussion)
I thought about treating the plant with a systemic miticide, cutting out the damaged tissue, and so on, but it seemed as though the base of the plant was affected, and a new Aloe striata is about $10, while a small bottle of systemic miticide is nearly $200, and rotation of different types of $200-$300/bottle systemic miticide is recommended. I would make valiant efforts for a rare or endangered species Aloe, but in this case it didn't seem to make sense. Goodbye, gorgeous. Owwwwwwwwwww! The price of Aloe love is high.
