Philodendron selloum (Thaumatophyllum bipinnatifidum), large deeply cut leaves on long stalks, forming a wide spreading clump.
A large-volume houseplant to place where it has room to open out. Indirect light, compost kept moist but not wet, misting appreciated in hot weather.
Note: the trade name selloum covers several cut-leaved philodendrons (bipinnatifidum, xanadu) which a photograph alone cannot tell apart with certainty.
