Monstera dubia is one of the smaller, lesser known monstera varieties, but it’s very beautiful and makes a great addition to any monstera lover’s houseplant collection. 
You can recognize monstera dubia by the small, heart-shaped leaves, speckled with both light and dark green. Since juvenile plants (the kind you’ll likely see indoors) lack the iconic monstera slits and holes, you may not even recognize it as a monstera at first! But the gorgeous light and dark green patterned leaves make this a beautiful plant in its own right, even without the fenestration. 
Fun fact: Monstera dubia is sometimes called the “shingle plant” because its leaves lie so flat against the trees it climbs in the wild, creating the appearance of shingles!
