While potting up stragglers in my collection this past weekend, I was somewhat surprised to see that a lone seedling of Nepenthes lowii "Gunung Trus Madi" that I obtained from Andreas Wistuba in 2000 (!!!) has finally generated a couple of 2.5 cm lower pitchers. Unlike its more robust cousins from other origins, these pitchers do not have bristles on the underside of their lids. These minute pitchers are also much more elongate than the other plants that I grow, although the overall plant morphology is the same.
This particular plant is, obviously, a painfully slow grower.
I know that there are people here who have both this ecotype of N. lowii and N. x trusmadiensis in their collections. Is it possible that this plant is a hybrid, or is the lack of bristles at this early stage normal/of no consequence? I also understand that there was some question as to whether older N. macrophylla in TC were hybrids - what was the final determination on them?
