Nice to see your Roridula coming into bloom. I am hoping you can post some photos of the flowers opened. What does it take to get viable seed from this one?
I believe Roridula can be manually self-pollinated. I'm a bit confused about the flowers though, one of them opened partially a week ago and then closed back to a bud again and neither has shown any signs of opening since. The second bud has been increasing in size though.
And the progression of an R. dentata seedling over the past month. These plants are certainly slow to get started but speed up significantly once they get to the point of developing leaves. Apparently it's also quite normal for the plant to be entirely unable to shed the seed coat and struggle to grow around it for a while. It makes me wonder how a plant evolved to grow like this.

I've been wanting one for a long time too, but definitely not willing to pay the $60 they cost in this country (and probably for a smaller plant too.) I definitely need to be careful with this one since I lost all but one of my flytraps over the winter. What I really need are some taller pots so the rhizomes aren't so close to the water.
Honestly pervillei is my favorite Nepenthes species. I was lucky enough to find seed-grown plants for sale for a very reasonable price so I bought 2 (and they sent me 3!) I actually need to split that third plant into its own pot since I had mixed up the soil for 2 plants and was too tired to do more once I discovered there were actually 3 plants in the bag. The media is 1 part peat, 2 parts sand, and 2 parts Turface. I spoke with someone who has been successful with a similar mix (though he used a bit less peat) so I thought I'd try it this way, rather than dropping $40+ on a bag of Akadama like a lot of people use.
Well, the "Black Knight" certainly has ramispina in it, but can't tell if there's ventricosa influence or not. Good luck with the sumatrana too; the leaves get huge long before the pitchers do for me, but pitchers are worth the space needed.

If it helps with an ID, this pitcher is more typical of what the plant has been producing. The plant is also extremely sticky - every surface is covered in drops of nectar. Nepenthes "Black Knight" by Nimbulan, on Flickr
Out of curiosity what conditions do you provide for your sumatrana? I've been told the natural habitat is unusually cool for the low elevation they grow at.
Don't think that does help; most of what I see is still the ramispina influence, even less of a clue with that pitcher than the other possibly.
The two sumatrana forms I have (the one that I got as sumatrana and the other that was labeled beccariana, but pretty sure it's another sumatrana) are both on the upper shelves of the greenhouse, where temperatures probably don't drop below 70 F in winter and definitely hit at least 90 F during the day in summer. They grow faster during the hot months too; your claim is the first time I've ever heard anything other than the general assumption that they're lowland to ultra-lowland. They like it slightly shadier than most thanks to the forest habitat (much like longifolia, though both species do just fine under strong light for me), but otherwise standard humid lowland.
What is it about the plant that makes you think of N. ramispina? I have one growing right next to it and am not seeing the resemblance myself.
I heard about the climate from someone who visited there - I believe he mentioned especially that the nights were unusually cool. I've heard that N. sumatrana often grows in direct sunlight myself. My plants certainly seem to be handling growing in one of the brightest spots in my grow space just fine. On the other hand while they grew quite fast last year, growth definitely slowed down a lot over the winter since I've been growing them at room temperature. They certainly handle the cooler temperatures better than mirabilis var. globosa though. I think I'll try moving them to my high light lowland shelf now that I have one set up and see how they do. I need them to grow faster so the moss doesn't completely smother them anyway!
Every photo I've seen of ramispina are dark plants with elongate pitchers, coloration being almost like a matte reddish to purple/black, and uppers are far lighter with anything from stripes of dark color on green background to a washed out or speckled look, lighter interior compared to the outside (sometimes straight white), small but distinct hip on the pitcher, and the ribs that replace the wings in uppers are nearly always strongly present even in hybrids, giving a nearly rectangular cross-section to the lower portion of the pitchers. Your plant presents all such characters to some extent.
