Last weekend me and my buddies located another location in Bau where bauensis (gracilis x northiana) thrives,probably the only place here and in the world.Searching the area we managed to locate 5 matured plants, considering the vast area. They have 2 variation-slightly yellowish and red but both displaying the peristome of northiana. The shallow pools of water is also rich in plant life,probably utricularia.From the pix what do u see,any comment?

The habitat ,taken 7.ooam,note the heavy mist before the sun appears.It was blocked by the hills behind.

Fantastic, Robert!

The nights do appear to cool off a bit from the way the mist hangs low over the hills. At 7 am, what temperature would you guess? Humidity is certainly 90 percent+
Have you looked closely at the root system of the northiana to see what it is growing in?

Hi Trent - roots system-fine roots are shallow embeded on loose decay leaves,the main root penetrating crack lines of limestone to gain foothold.Very fragile indeed and have to be very careful when moving the pitchers or leaves.

As it's inland night temp.during hot/dry season can lingers around 28 °C, wet/rainy season night temp around 23°C.Day temp in Bau limestone is no different with other lowland area.

That red northiana is just killing me! I've come back to that picture several times this morning! One of the most beautiful of all Nepenthes...and most difficult to grow in cultivation.

Hi all,thanks for the reply. Trent i suspect the difference between captivity is the condition the roots beneath received from limestone-alkalinity,calcium carbonate.Just my thought.

Another northiana having all red peristome in the same locality but I didn't see any different in the growing condition.It's mind boggling

Wow those are fantastic shots (and good info about the substrate of northiana)! You're so lucky to be able to wander outside and take photos like that! I Can't wait to see shots of your next trip!

Great photos, Robert. The N. northiana is stunning.

Really appreciate your sharing of habitat photos and natural growing conditions. Your posts are an educational treat.

Many thanks,
KPG

Man those are fantastic!
I don't know if you want to swing the aquatic plants to a different spot, as those might be a Utric(I am not sure though) and some of those nuts(Fernando, Barry, Pyro) might want a peek.
Doesn't N. northiana look like it's made for flying insects to "bank" right in? If a pitcher was six feet tall, it would be perfect for a football throwing contest!

Hello,
thank you for the wonderful pics, northiana is certainly very beautiful! Maybe you should take a good pic of the root and substrate area if you visit the area again...I find it quite hard to 'picture' the growth habit that these limestone plants (and campanulata) have...
thanks again!

Swords,KPG thanks for the comment.Griffin i will post again in the proper section when i come back with more pics after the investigation. Lam, initially i was going to take photo sample of the roots and substrates but my mind was on another when the pitcher was spotted,only to realised when i reached home. Definitely am going again. Kinda good excuse my buddies will not refuse.

Lam,again it's difficult to illustrate the roots and substrates in pics as the colour of dead leaves and shadows will be darken due to photo processing to bring out color balance.One way to solve is using black and white, or and I tried to imitate infrared process by first desaturate using photoshoppe. As we are more used to colors most will not like the results but it is best used to show,in this situation, the partially exposed roots and substrates. Try Imagine a layer of decay twigs and leaves where the plant taken root, more fine roots and the main root penetrating limestone cracks to have a firm hold beneath. Photo as follows. No doubt i will post again with a better images, but for the meantime
