Here are some pics of the same Wistuba N. hamata, from last year at around this time and some more from just this month.
Last year this hamata was a small rosette, only 2.5" in diamter with a pitcher barely 1.5" tall.
Now this pitcher is very close to 4" tall.
Last year's peristome,
The peristome now,
The plant is growing in a 6" plastic pot, and easily extends over the pot's rim with it's new growth. All of the existing pitchers have had their leaves overgrown with live sphagnum. The new leaves are now forming new pitchers with a few of them being inflated. This next wave of new and larger pitchers should prove to be quite impressive.
And last but not least, here is a shot of a prolific ventricosa from CZ Plants, that was thrown in as a bonus with one of my orders from them. This plant is always in a constant state of pitchering, despite being potted up in only a 4" pot and sitting on my bare concrete basement floor, under lights. As you can see it has a continuous skirt of pitchers encirlcing the pot. This has proven to be one of my favorites, due to it's extremely short internode length and pitcheing proclivity. In fact, it is now producing uppers and it hasn't started to vine yet...a real beauty.
