Your most reliable source would be the builder of that model home. Since it is new there should be no problem finding the reference number.

Looks like some form of terrazzo, which was very popular in the 40's - 70's. What was used to create it may differ -- rock chips, tile chips, marble chips, etc -- and depending on what they used, it might be a bit of hard labor to remove -- it's embedded in concrete-like filler. You have to get power tools in there to essentially chip up that layer of cemented-on substance. Might as well get rid of all of it once they're in there with the tools and mess -- that will allow you to replace the subfloor and have a broad choice of what you use for a new flooring. Best of luck!

Maybe I'm wrong, but it sounds like what you are asking is if it is one of the popular named varieties of which there are many. Here are a few that seem to be most popular right now: Thai Constellation, Borsigniana Variegated (aka "Albo Monstera"), Marmorata, Aurea. To be perfectly honest, I dont think your monstera has enough variegation at this point to tell. It's very low variegation which could indicate that it was never a named variety but a sport variegation. This would be when a regular green Monstera Deliciosa produced a stem with slight variegation and the grower chopped that vine and propagated it to try to see if it would produce more. Since the seller offered no definite identification, At this point, all you can really do is wait and see what the plant does. But I don't think you can officially call it by any of the names since you will never know unless the seller can provide evidence of the mother plant's identification. Just enjoy it for what it is. A monstera deliciosa with some variegation.

Hi Everyone Can anyone identify this algae. I have a large 1/2 acre quarry pond, 8’deep. The water is green, but there is no algae floating in or on top of the water. When put in a container the water is clear. However, anything submerged in the water, including rocks, pump hoses etc. is covered in this slime. On the rocks, below the water, they look like rubbery balls, and if dislodged, float to the top, break apart easily as well. We are aerating the pond and have been swimming in it for 2 years, no problems. There are a few frogs, 3 turtles and too many goldfish. The latter, which are would like to eliminate, as they are invasive.
