More pics YAY.. had to use the flash though as the weather is rather miserable today. Note that pitcher size is from the base of the pitcher to the point where the lid connects to the top of the peristome.
N. bongso pitcher approximately 2.5"(6cm). I took this one to show that at this point there appears to be nothing protruding at the base of the lid. The pitcher opening is also wider and rounder in shape. Color is not set yet since this pitcher is fairly new. It will be dark purple soon.
Picture of the N. bongso plant. I took this one to show the more spoon shaped leaf particularly where the tendril attaches it appears more round than in the N. ovata I looked at.
Large pitcher on N. ovata.. still don't see much of a crest under the lid on this plant. Pitcher approx 5" (13cm). Also appears to me the pitcher opening is taller and narrower with more of a tear shape to it. This pitcher will darken more and the peristome will reflex still.
Picture of the large N. ovata plant. Took this one to show the leaf tip being much more pointy and extending out onto the tendril more. I looked at the other N. ovata from the same source and they all appeared to have this leaf shape.
Pitcher from a different plant (same N. ovata source) which is showing a slight crest. Approx. 3" pitcher (8cm).
I do have N. ovata and bongso from other sources but plants are small and show little differentiation. Perhaps the crest only develops on large mature plants if it is going to develop at all. As plants get larger it will be easier to compare between different sources as well.
What I find interesting with Robs plant is the peristome appears smoother with less pronounced ridges and teeth. The upper portion does not appear narrow and elongated. As well as no stripes on the peristome and purple blotches inside the pitcher.
