Question

Unidentified nepenthes  

Uunidentified 1   Dear Sir
Could you help me to recognize my three nepenthes.
Thank you.

Answer
Hi Igor,

The tallest plant is some clone of Nepenthes x ventrata, which is Nepenthes alata x N. ventricosa.  It looks very much like a super common one in the nursery trade colloquially called "deRooses alata".  It's produced by DeRoose Plants of the Netherlands.  If it's that one, the hybrid is (N. alata x N. ventricosa)x N. alata.

The shorter plant with the dark pitchers looks like the darker form of Nepenthes sanguinea.  It has the characteristic blood-red color it's name refers to.

I wanted to mention also that identification of Nepenthes, especially hybrids, is going to be an imprecise affair at best.  The genus Nepenthes has so many species that look very similar, and because the hybridize so easily, identification of complex hybrids can be nearly impossible.  It's similar to the situation with many orchid hybrids.  Here's a good resource:  http://lhnn.proboards.com/index.cgi?

Good Growing!
