My growing collection of neps

This one's been stumping me for a while. It's some random seedling Nepenthes that hitched in with a pot from Willy's TLC box.
Looks like it's currently variegated, but who knows if it'll revert to green or go fully achlorophyllous.

Feel free to chime in with possible IDs. I haven't a clue.

Several neps are making good progress. I think I have my growing conditions mostly figured out now.
I'm able to get a pretty good temperature drop at night by directing cold air from a floor vent into my shelf with a couple fans.

BE-4099 villosa x hamata
Latest pitcher just popped, bigger and toothier than ever.

hamata x edwardsiana AW13
Its most recent pitcher is just starting to open. It's also the largest yet. It should be fully opened in a couple days.

BE-3225 villosa
Just received this today. It's tiny but looks healthy.

I picked up a bunch of wifi thermometers to track what was happening in different areas of my shelf.
Data from the first 24h of tracking shows how big of a role evaporative cooling seems to be playing in dropping the temperatures at night when I have fans running and dry air blowing in from the floor vents.

Also, N. truncata has made its biggest pitcher yet.

Very interesting!
I spray 7 times 15seconds, but they are all focus during the day to compensate the light's eat:

My tent is probably smaller with less evaporation.
By the way, the huge humidity drop is the AeroZesh that purge the eat for 30 minutes

Pretty neat. My plants are on an open shelf so while I don't have to worry about trapped heat, I do need to run the misters all day to keep humidity above ambient. This also helps reduce watering needs.
The evaporative cooling was an originally an unintended side effect but it's very convenient so I set up fans and air guides to maximize the effect. Without the misting and fans, the central air conditioning would only drop my shelf to around 20 C.

Yes, me it's misting only on the top shelves... so I'll add 4 more on the lower shelves to be able to reduce watering.

If ever one day you are motivated to do an interview with me... just saying ;)

Couple fresh pitchers:

trusmadiensis AW01:
This was received 2023-05-18 and has just grown its first pitcher. It's not fully open but already looks great.

BE-4544 aristolochioides:
Received 2023-04-28. This has grown several pitchers over the last 3 months but they were all very small. Only this latest pitcher is larger than the ones it came with.

The plant is filling out nicely with 3 pitchers and two more on the way.

This is a trichome from the upper surface of a N. truncata leaf:
1692024740147.png

These trichomes are made of layers of cellulose fibrils which give them birefringent properties. We can see this using polarized light microscopy with a pair of crossed polarizing plates:
1692024804585.png

Here the light source is polarized north-south and the analyzer is oriented east-west. Normally the polarized light is blocked by the analyzer, but the trichome hairs oriented at around 45 degrees rotate the polarized light enough that the resulting beam of light can pass through the analyzer and are visible. The hairs oriented closer to the north-south axis are dark since they do not rotate the polarized light enough to pass the analyzer.

I previously made a couple videos showing spiral fibers being pulled from nepenthes leaves:

These fibers are also present whenever I section a leaf to look at under the microscope (arrow).
25573


The fibers are made of cellulose so they're birefringent and easily seen with polarized light:
25574


It's hard to tell which cells the fibers are coming out of because the cells are destroyed when the fibers are pulled out.
I reground this razor to a single bevel in hope that I could make a section of the leaf while keeping the fiber-containing cells intact.
25575


Using this razor, I'm able to make very clean sections of leaf. You can see the individual tubes that make up vascular bundles and also the spaces between the cell walls:
25576


I also sectioned the leaf longitudinally along the vascular bundles to look for those fiber cells. Here's what they look like in brightfield and under polarized light:
25577
25578

25579
25580


I don't know what the function of these helically banded cells are, but they're distributed all throughout the leaves. Maybe they're some kind of tracheary element like what's found in lotus: https://www.sciencedirect.com/science/article/abs/pii/S0304377011000817

I love your scientific observations man. As someone who was a researcher in the past myself, it really gives me a warm feeling lol. You really should publish a paper or something...ofcourse publication costs aren't cheap, but might be worth looking into it.

It's been a while since I posted this plant.

N. edwardsiana (Tambuyukon):
I received this as a basal cutting from Jake Chickenbark, who very kindly held it for several months while we waited for the weather to warm up enough for shipping.

Here's a photo from June 2023 showing the root development:
I figure this is about 6 to 7 months after it was removed from the mother plant.
1694457324685.png

Here it is about a month later (July 14, 2023), pitchering from the first leaf it fully grew in my care.
1694457392628.png

Here it is Sept 7, 2023:
Its growth has sped up a lot since the above photo, I figure the roots are finally well established by now.
1694457436477.png

Its newest pitcher is much toothier than the previous ones too:
Very exciting, can't wait to watch this plant develop

Fortunately enough, my mother plant has produced another basal :D
