Nepenthes lamii (Doorman's Top)
Lately, it has turned out that the plant that was formerly circulating as "Nepenthes spec. Doorman's Top" is the real N. lamii, while the plant formerly known as N. lamii turned out to be something new - N. monticola!
Unfortunately, this is a very slow grower, but is absolutely stunning when big!
In order to get some insight into the new status of N. lamii and the description of N. monticola, please see for details:

A highland plant that needs cool nights, a lot of light and humidity. It’s a real tropical ‚alpine’ plant and is recommended to growers with a good experience in growing Nepenthes. Besides cool nights it needs an open mossy substrate and a high humidity. In recent times dead Sphagnum of very high quality from Chile and New-Zealand became widely available. A mix of such moss with horticultural-grade Perlite, a bit of good quality peat-moss and pinebark-choppings makes an excellent mix. However, when using Sphagnum, it’s important to allow for a good drainage as otherwise, Sphagnum has the tendency to rot quickly. The proportion of Sphagnum in the mix ideally is quite high.
