Another nice example mrmicro - you're off to a good solid start I'd say!
Keep up the good work, it's great to see your progress.

p.s. Have you had a look over the late Mr W. Dioni's work featured in this website? I started from scratch by following his fine examples.

Well done, good cleanly presented work.

thank you guys so much for this encouraging words
i really appreciate it .

wait for some crazy creatures videos (from my aquarium ) in the next couple days .

iam not very Familiar with mr W. Dioni's work can you give me links for some of his posts.

thanks again.

Aha! Hi Bill!
Yes, we've just returned from yet another stay in the Yorkshire hills! My Darling Wife lets me take a 'scope (sometimes two... ) with us - together with a 'small tissue collecting kit' and a mountain of books! What a fine lass she is.
I spent a little time exploring the gardens of the cottage and found there to be a thriving and really quite extensive mono-clonal patch of the elusive (around our area that is to say) 'Fox & Cubs' AKA Pilosella aurantiaca - yes, It's another weed!

Also I've been able to add Sonchus.arvensis to the infamous Sonchus.oleraceus and Sonchus.asper specimens collected and sampled in my lab (and of course featured seemingly-endlessly in my early adventures and posts here...). There's best-part of a whole plant sitting in various jars of FAA now, along-side the other two species.
I've a feeling I'm going to be pretty busy with the mighty Shandon soon!

I'm also battling the super-hard tissues of the dratted Sunflower-stem - pity they're so difficult as they have quite spectacular secondary vasculature complete with quite massive bundle-fibers.

I'm also studying the branching-patterns of mosses, and have been for a couple of months now. The distinction between so-called monopodial and sympodial branching, coupled with the position of the perichaetia, is highly valuable as a taxonomic resource but takes a lot of very detailed study, and lots of plain-old practice! Supremely rewarding and enjoyable though!

I've developed quite an interest also in the variability of leaf-form of the individual plant, another great aid to ID and taxonomic understanding for me I find. Apparently the term is 'heteroblasty' - really quite fascinating when seen 'in the flesh' as it were... Also can be very noteworthy with moss classification and ID when I can actually see the truly tiny signs of this along a moss-stem.

I've many slides made and am currently cutting some longitudinal (ideally tangential) Sunflower-stem sections, with limited but increasing (slowly) success (in terms of the actual morphological-detail captured). Unfortunately one good section-plane and subsequent slide produced may only amount to about 1-2% of a batch - very time-consuming and labour-intensive, but worth the effort for a permanent mount I think!

So much on-the-go, I really must post perhaps a few images as I do have quite a few beautiful preparations/slides that folk may like to have a look at.

Always following the forum several times a day usually, keeping very busy, but mainly with projects that most may find a little bit dull I fear. Mind-you, I have been thinking about some demos of 'slide-surfing' sessions just to show how much 'is in there' when a slide is really examined closely - that would be fun to do I think. I really must get something ready for the forum, I've neglected my posts awfully of late, in spite of my busyness in the world of plant anatomy!

Good to hear from you Bill.

Hopefully back soon with a post or two.

Thanks, John.. I am looking forward to whatever you are working on and care to post!.. I enjoy everything that you write about... All that you share is of the utmost interest to me.. Your material is presented so well, it is as I am there observing!...

The Best,
BillT
