Woody climbing stems of Bramble (Rubus fruticosus agg.) showing backward-pointing spines and axillary buds, about 30 cm long.
The backward-pointing hooked spines help the stem to hold onto twigs and branches as it climbs. Buds can clearly be seen in the axils of the old leaves.
Some of the longer branches eventually arch over and touch the ground. A new plantlet with adventitious roots may then develop at the shoot tip and the plant reproduces vegetatively.

This image shows a general view of a woody climbing stem of Bramble (Rubus fruticosus agg.) in an Ash tree (Fraxinus excelsior).
Some of the longer branches eventually arch over and touch the ground. A new plantlet with adventitious roots may then develop at the shoot tip and the plant reproduces vegetatively.
The stems are approximately 1 m long.

I ripped thin strips of Douglas Fir to laminate the external stem in place. It took some coaxing, but straps and temporary screws proved adequate.
Made with hollow space inside, made with 2 empty cans, and in a mold, or rather a brass vase, cone shaped, lined with a bag. The crevices from the bag make awesome, natural looking lines in the concrete, if painted with a little paint plus glaze it will look almost like a reeal mushroom stem.

A sampling of the glazed mugs that will become awards for an exercise/health challenge that ends on New Year's Eve. On average, they are 6" tall and some of them include a running shoe finial as part of the handle. All are wheel thrown using white stoneware, sprayed with a combination of layered glazes, then fired to cone 10 in reduction (approx. 2300F).

"Aerodynamic" was THE big catch phrase for bicycles by 1980... And no denying these stems were aerodynamic in the best Art Deco sense of the term.

A rare Routens stem, un-atached to a frame . I really like the aesthetic of these stems, with the pointed top curl, and the tapered handlebar clamp., Integrated bell mount, very functional.
just gorgeous.
I'd love one for my own Routens!!
The hydrangeas for the wedding arrived with each stem individually wrapped at the end with moistened cotton.
We had Koji's bike clear coated with a semi gloss, and black lettering. super stoked on how this looks!
