Hello Arif,
I am way ahead of you on the nursery idea, but the locals know very little about the "wild" plants. I am going to be opening my own nursery very soon, & I am actually talking to the owners of the nursery in town about buying property from them for this purpose. Since I will be mainly exporting my business will not hurt theirs. What philodendron did you think these are? I collected the pale one as well. It did not even seem to notice that I moved it to a new location.
Once I get this nursery & botanical garden set up here , I would love to invite you & all of ATP that would be interested to come visit the botanical garden. I am looking for Liana now to compare them.
