Philodendron uliginosum is one of the few meconostigma Philodendron species with entire, smooth leaves with no lobing or divisions. Others like this are P. corcovadense and P. tweedianum. This plant is the third one of what I call the "big three" - so named because they all thrive with roots in marshy or submerged habitats. This characteristic is important in our quest for meconostigma hybrids that are resistant to Erwinia infections. Erwinia is the bane of Philodendron species that cannot tolerate too much rain or moisture.
The plant shown above was photographed in a friend's plant collection.
The plant shown above is one that has leaves virtually identical to the leaves on the plant I saw in my friend's collection, but the resemblance stops when you look closely at the stem of each of the two plants. This one I have nicknamed the "shark tooth Philo" due to the numerous spines on the stem. These spines are very similar to little shark teeth, hence the nickname. A close-up of the young stem of this one is seen below.
