This has become one of the most interesting threads I've read on any =
list, and the addition of pictures enhances it enormously.
I'd just like to distinguish the use of the term "random" from diffuse =
which may also be visually random. "Random" as in this Amorphophallus ==
is "sectional", involving relativley large sections. The other kind of ==
virus-based infection I was talking about is nowhere near as obvious, =
but "seems" to lie in randomly dispersed much smaller areas, at first =
appearance--about the size of individual cells, and then sort of =
gradually invading an area until the whole area may become chlorotic =
and die.
