You are correct, Bihai. The tag on this one does say "Anthurium Andreanum" its my other anthurium that I suspect is an amnicola, also labeled and A andreanum. Here's some pics of her: She's in glorious good health, has been from the moment I bought her. But what can I do to nurse the sick fellow back to health? I'm a newbie to the world of Anthuriums, so any help would be appreciated :). Should I repot with orchid bark? Water more/less often?

Wow, it is puzzling. It doesn't look like an ower-watering issue to me, but since we're not coming up with any more likely possibilities, then it is something to consider. This late in the year, it has likely stopped growing, even in Florida temperatures. Pothos tolerates drying out pretty well, so let the top couple of inches dry between waterings. How long have they been in that soil? Did they grow well all summer? If so, they might be a bit pot bound now, which can cause some dry spots in the soil, or some roots to become so restricted that they aren't able to draw enough water. It isn't the best time of year to re-pot, especially if something else is causing the problem, but you should at least check this. Can you pull the entire plant out of the pot with the soil and rootball intact? If so, a photo would help us. Check the root ball and medium for dry or mushy spots, for discolored or necrotic roots, for root parasites, crowding, etc. A few, small disrupted places in the root ball where you dig in to check the condition won't hurt it, even this time of year, and if it's very pot-bound, you can plop the entire thing into a larger pot of soil until the spring when you can do a better job or repotting, detangling, root-trimming, and so on. What parts of the plant are affected the most? Were the oldest/lowest leaves on each stem affected first/worst/most, or is the damage worse on the younger, more tender leaves? Are there any parts of the plants that aren't affected? When was it last fertilized, with what, and how often? (Do not fertilize it now- that's the worst thing one can do to a sick plant if the illness isn't due to fertilizer nutrient deficiency.) It might just be lighting, but the plant in the upper photo appears to have an overall yellowish pallor. That would support Tiffany's hypothesis of too much water. Also, I see a yellow leaf near the base of a stem in the second photo near that little sprig of Acacia or whatever it is that's taken root there. Some yellowing is normal, but check through the lower leaves for more yellowing. Too much water or nitrogen deficiency both tend to affect older/lower leaves first. Evenly yellowing lower leaves is more indicative of too much water or poor drainage, while yellowing that begins at the leaf margins is more often nitrogen deficiency. Other things can cause yellowing though, and that curious staining appearance isn't typical of either issue, so don't fertilize at this point. More photos wouldn't hurt: Entire plant Root ball free from the pot Close-ups of the "stains"

Very likely a case of anthracnose, a catch-all term for several different fungal pathogens that result in an assortment of leaf spots and early leaf drop. These tend to be highly weather related and high heat, high humidity and heavy rains can all contribute to the cause. But they are generally considered to be mostly cosmetic and seldom do any significant damage to an established tree. Control or a specific treatment is generally not warranted. Just clean up and dispose of ALL the fallen leaves to prevent spreading or overwintering the fungal spores on your property. And while probably not necessary, you can use a dormant oil spray in winter to smother any spores thay may be lurking on any stems or branches.
