There has been some recent discussion about morphological variability -- even within species -- and the occasional difficulty with identification. While that is certainly not the case here, I have photos of two pots of the very same seed-grown batch of Nepenthes hamata -- grown under identical conditions, side by side; regardless of the amount of light afforded it, that second pot will not color-up any further than that, and remains, for the most part, a lightly-mottled lime green -- but with a more pronounced, larger peristome. That first plant produced two basals within eighteen to twenty months of germination and is far more vigorous . . .
