I think Philo's may be discussed more often on the Aroids Forum:

I used to grow quite a few Philo's years ago, lost some to winter freezes, others when I had to travel a lot when my mom was sick and I gave some away. I only grow a couple of of them nowadays.

'Prince of Orange' that I got this past spring. I lost a large one to a freeze in 2010 and the second plant was labeled 'Lemon Lime' (x domesticum) but I'm not certain of that ID:
Bought as P. domesticum but I can't find any info on a Philo by that name:
This one was labeled Philodendron brandtianum but I'm not certain that's correct:
P. erubescens 'Pink Princess':
