Hi Everyone,
There seems to be some confusion about N. 'Miranda'. First, it has not been around since the 1960. It comes from tissue culture. Tissue culture of Nepenthes didn't exist in 1960.
The parentage is trademarked - "proprietary information" as the supplier says. We believe it to be N. maxima x Mixta. N. Mixta is not the same as N. Superba (made by James Taplin in 1880 = hybrida x hookeriana), and is not to be confused with Mixta var. Superba. Rattler is almost correct, but there are no female N. Mixta outside of Kew Gardens, so the female parent is most likely maxima.
FYI When naming a hybrid the female is always listed first.
Tre, the photo on page 13 of Gordon Cheers book shows a Mixta 'Superba' not Miranda (or true Superba - which looks nothing like Mixta). Quite often, Mixta superba is mislabeled as Superba, and that is an example of misconstrued information - so typical in Nepenthes hybrids.
For a while, Deroose plants was wholesaleing Miranda as "N. maxima 'Miranda'" and have since dropped the "maxima". Deroose names thier plants after the pod parent, or "mom", even if it is not crossed with the same species (hence all of the tobaica confusion, and ventrata being called alata).
The ICPS doesn't officially recognize 'Miranda' as a cultivar, even though it is probably one of the most popular Nepenthes in history.
Here is a pic from our greenhouse. Pitcher is 15 inches from the bottom of the tendril to the tip of the lid.
