Fly doo-doo?

 

[ps3isawesome]

sorry the pictures are kind of bad. I try to scrap it off but it def looks like little black holes.

May just be nectar pores then, though I usually see these mostly on the top sides. Wait till the experts weigh in

 

[thez_yo]

Yeah, some of my plants look like that too, and for years. Afaik they're not diseased. I'm assuming it's just nectar.

 

[ps3isawesome]

thanks guys! appreciate the feedback.

This is the first I've heard about "nectar pores" on neps, especially showing up as frightening black dots on the leaves. I haven't personally seen these on my plants, but I'm hoping someone more versed can chime in, because this would be worrying to me if I saw them on my own plants. One would think if it were a natural product of the plant it would be either uniform or symmetrical in nature, rather than scattered randomly over the leaf surface. :/

To me it looks like bugs, but then again I cant tell because of the 2 bit resolution on the pics.

Ill take some pictures of one of my nepenthes that is breaking out with nectaries for compairing

 

[ps3isawesome]

Hopefully this pictures are better, let me know.

I'll go ahead and look at the neighboring plants to see if it's spread.

at first i thought it was nectar glands because I've seen them on my ventratas. But honestly this perfectly circular dents looks like bite marks...

thanks!!

They are nectar glands. Nepenthes glandulifera is particularly pronounced in nectar gland expression. I suspect they developed on the leaves as a sort of side effect from the same specialized glands in and around the traps. If you look closely you can see the same glands on the traps and tendril of this glandulifera specimen: https://www.flickr.com/photos/99611974@N05/22516098647/in/dateposted-public/.

phew, i can sleep better tonight. Thanks guys!!

 

[NemJones]

YES>
those are definitely nectaries.

 

[Dexenthes]

Looks like a glandulifera hybrid to me. . . what is the heritage of the plant?

 

[Heli]

Dex, this is a pure sibuyanensis.

 

[Dexenthes]

Oh! Stupid me, it's in the flipping title.

Super glandy for a N. sibuyanensis, I didn't know they came like that.

 

[Clue]

Pretty prominent extrafloral nectaries, but nothing to be concerned about. Here's some shots of a young N. glandulifera:

Those are definitely just pores, my own N. sibuyanesis has always had them and is perfectly healthy.

 

[vdub804]

yup definitely nectar glands.

 

[Fero]

Could they be scales?

 

[Cthulhu138]

Could they be scales?

No, as stated several times above they are nectaries. Very common in some species of Nepenthes.
