There are others that you can see in the Kondo book, like N. clipeata, that
have the same sort of peltate leaf apex (as Kurata calls it in the book,
Nepenthes of Mt. Kinabalu). This is when the point the midrib turns into a
tendril occurs before the leaf apex. Here's a rough pic:

I don't have a list of all the species of Nepenthes that have this same
kind of structure.

I read somewhere that the Nepenthes pitcher is a hollow midrib and the thing
that looks like an ordinary leaf is actually the petiole. I don't remember
what the actual leaf was claimed to be. I would guess a vestigial leaf is
the ribs on the pitcher. BTW, there is a common tree (perhaps
the Magnolia) that have no actual leaves, but the things that look like
leaves are actually expanded leaf bracts.

I had a D. intermedia do that this past summer. It just produced a single
leaf that died in about a week. I guess it got too dry. I also had a
D. capensis produce a leaf that was forked. Another wierd thing that
happened last year was a plant I found growing in the soil of one of my
Nepenthes. Turned out to be a nice rabbit's foot fern. I have never had
one of these and don't know how it got there.

The plant with the wide petioles is most probably D. pulchella.

BTW, Glasshouse Works will be selling Nepenthes this year. Perhaps up to
45 different species and hybrids.
