Caryota is a genus of palm trees. They are often known as fishtail palms because of the shape of their leaves. There are about 13 species native to Asia and the South Pacific ( Wikipedia )
We do have many varied types of palm tree here in Arizona, and some of the fruit or seeds look similar to photo 1 and 3 in you collage, but the fruit or seeds sprout out from pods, and not stalks, very informative info on your well presented collage, Thank you!
Fishtail palms grow here. Just the other day I was taking a closer look at one in the park with the mangrove forest that I like to visit. Great collage, Pyrrhula!
