Philodendron bipinnatifidum (common name: Philodendron, selloum).

Thank you, Lisa and Bob. By the way, Bob, the dyckia seeds have sprouted! The neo and fosterella seedlings are growing, albeit very slowly.

Your plant is a Lipstick plant, aka Aeschynanthus 'Mona Lisa'. The info on the web says: Related to African violets and gloxinias, lipstick plants are members of the gesneriad family. It's easy to see the reason for their common name since the lobed red flowers emerging from a maroon sheath do resemble lipsticks in tubes. Natives of the West Indies, the plants grow as epiphytes in the wild, but they're most comfortable in hanging baskets in the home. Blooms should come and go all year if the plant has suitable bright light and adequate water. The soil shouldn't dry out completely, but should not be soggy. Like all plants from the tropics, lipstick plants suffer in low humidity. Misting the leaves will increase the humidity.

Alocasia are quite variable in cultural needs, depending on species. Some will grow in water, some will rot in water. Colocasia generally like lots of water, but some will still rot if sitting in it. Those in the photo are just leaves not a whole plant. So they need to be sitting in water but will have a limited life, similar to cut flowers.
