Sea Coconut seeds?

[Barolo]

Hello. I'm brand new to this site, and am excited to e-meet other palm enthusiasts from around the world. I am in Brooklyn, N.Y., and recently saw a bin of these "Sea Coconuts" in Manhattan's Chinatown (see attached photo). They appear to be larger, and not as smooth or as round, as Manicaria saccifera seeds, which I've seen online is sometimes referred to as Sea Coconut. As far as I could get from the non-English-speaking clerk, this is called "Hoi Tai yeh" (my transliteration) in Chinese (not sure if this is Mandarin or Cantonese), though another clerk called it something like "Hoi yeh wong".  I don't know if they're viable, but bought one, stuck it in a quart bag half-full of very damp vermiculite, with a shpritz of off-the-shelf fungicide, and will wait until it either sprouts or rots. Any ideas about what this, and if so, what the germination time might be? I can take closer shots of the seeds, if this helps.

I also have a fishtail and a foxtail palm that have been living happily indoors in a small NYC apartment for years, though, of course, they are slow growing under these conditions.

Sounds like Cocos nucifera var. aurantiaca.

I bought a coconut from the stores today, with similar expectations. Keep us updated... and welcome to the forums!

they look like "normal" coconuts to me, just without the shells, only pulp
