Christer,
Would you know what area the seed came from? Its probably the Philippines, but would you know which mountain/island?
I am trying to keep all my clones separated by mountain, island, etc. so as to develop and maintain some pedigree bloodline should ever a male or female arise from that region. As far as I am concerned, crossing two species N. truncata is like making hybrids if they are from different regions, etc.
One excellent example is N. copelandii. There are two forms that are sold and they are very very different from each other. Mt Apo form is smaller, more tubular and compact growing, while Mt. Pasia is more vigorous, has longer leaf blades, has really giant pitchers with a distinct swollen lower and grows faster than the Apo form. Crossing each of these together would not be in the best interest for maintaining species. Thus crossing a red leaf truncata with a striped peristome truncata would be a "hybrid" cross even though both are N. truncata.
