Pelargonium hairs: follow up

Cyclops · Post by **Cyclops** » Mon Oct 23, 2006 2:20 pm

I posted a pic a while back of the surface of a pelargonium leaf showing tiny globes of sticky liquid. I tried to get a closer view of those glands, this time a lavender scented one(P. dichondraefolium)
I had no light source other than the ambient light so its not a great pic but you can see a couple of round white glands.

Are these the source of the smells these plants produce?

Thanks Bernard, it seems another plant has similar structures-cannabis!

The Capitate-Stalked trichomes of the cannabis plant.

Which look quite like the stalked hairs on my pelargonium plants!

Well, in fact many plants feature these. Here's an example from our german forum:http://www.mikroskopie-forum.de/read.ph ... #msg-22126

Search me for the english name of that plant, I hardly remember the german ones!!

Thanks Bernard, it seems it is a Habichtskraut Trichome, whatever that is in English!

Our friend Mr. google just told me: it's "hawkweed" in English.

I forgot to deliver the translation:

here again the glandcells of the orange- red hawkweed, i.e. in comparison: stereo, compound-brightfield-darkfield.

What you could do Cyclops is try and collect the droplets on a piece of paper and move away from the plant and see if that concentrates the aroma of the plant. You might be able to tell if the smell is in the droplets.

Good idea, might just have to try it. The only thing is the oil is so strong that you only have to go near a geranoium and its all you can smell for the rest of the day!
