I've long wanted a 2X for my MM-11 setup since 4X/5X was often too tight for a good "overall". Came across a good price on a USMC 2X, so I bought it. One of my first subjects was this rosehip. This was the first time I ever opened one and had a peek inside. Interesting.

Lovely images, I cannot find any critters in there either?

Very nice.
Thanks for sharing.

Re: Inside a rosehip
Excellent! Where I grew up the kids used to open these up and use the hairy seeds as an alternative to the “itching powder” that was sold at the local joke shop. I think the hairs are an irritant and if you don’t de-seed them before eating they can have an unpleasant effect, I believe that they are called “butt scratchers” in France.
Re: Inside a rosehip
The hairs themselves are quite interesting, and seemingly have either a central channel or (as I think) they are folded around to form a kind of spiked tube, sort of like a blade of grass.
The five-sided folicular organ at the base of the hairs and the structure of the hairs where they emerge from the folicle is also fascinating (pics in link below.)
If you section the hip tissue, you will find the innermost tissue layer growing hairs and supporting achene development is heavily laden with calcium oxalate crystals. Meanwhile, if you can get the achene sectioned, you will find CaOx of completely different morphology proliferating in the endosperm.

I'd like to know what the hairs are made of. A friend who has studied them a long time says they are a silicate material, but he can't find the reference. I suspect it's more like gypsum. Anybody know?

Lovely images! I like how the hairs in the 10x image are almost transparent, or appear to be.

Amazing images as always by Charles!
I'm pretty sure fine brittle plant hairs like these have silica walls like the stinging hairs on nettles. I haven't heard of gypsum, calcium sulfate, deposits in plant cell walls.
I have a scanning electron microscope at work with an energy dispersive spectrometer (EDS) on it that can ID elements in the sample you are examining.
If I can find a rose hip, I'll check and see what the hairs are made of.

That was my first post here, looks like I need a better Icon / Graphic!

Re: Inside a rosehip
Nice macro shots Charles, lots of find detail.
On another note DK books was trying to contact you but reached me instead - I gave her your web web site and also this web site. It was a lady from India looking for photomicrographs for DK (Dorling Kindersley) book project -I hope she connected with you about 3-4 weeks ago. If not email me and I will try to connect the two of you.
Cheers
