Philodendron billietiae [(bi·lli·et·i·ae) pronounced “bili ətiā”)] is a hemi-epiphytic species of plant in the genus Philodendron native to Brazil, Guyana, and French Guiana. A relatively recent discovery in 1995, P. billietiae is known especially for its distinctive orange-yellow petioles and wavy, ridged leaf edges.Philodendron billietiae is commonly mistaken for Philodendron burle-marxii due to their similar structure and coloration.
Philodendron billietiae was first discovered by Frieda Billiet in 1981 in lowland tropical rain-forest in French Guiana. Living material from the plant was collected and introduced to cultivation in the greenhouses of the National Botanic Garden of Belgium at Meise.[1]
