Despite its name, the Saddle Leaf Philodendron or Split-Leaf Philodendron belongs to the genus Monstera and not Philodendron. Like Philodendron species plants, it contains insoluble calcium oxalate crystals similar to other plants in the Araceae family. Chewing or biting into this plant will release these crystals causing tissue penetration and irritation the mouth and GI tract. VERY rarely, swelling of the upper airway occurs making it difficult to breathe. See Oxalates (Insoluble) for more information.
