Re: [Aroid-l] Photos of Z. zamiifolia seeds

From: Walter Turner <wvturner at gmail.com> on 2019.10.25 at 14:16:16(24259) Hello, Tom. I know to appreciate a positive comment from you. First, Wuppertal is some 25 miles NNE of Cologne. With some 350,000 people, it is probably Germany’s largest city that no one has ever heard of. That’s probably because this is the most highly populated area of Europe and even a city of this size is lost. People who do know about Wuppertal know it for its suspension railway, the schwebebahn. That line runs about ten miles through the Wupper valley, for most of the stretch hanging above the river. Which would be called a creek in the US. As to publication, I don’t think I could add to what I wrote. That was all I know about the ZZ seeds. I have a lot of pictures, but the ones I posted are the best and most illustrative. I spent my working life as a chemist, and I have a number of publications to my name. My friends are teasing me about this latest one, without co-authors or peer review.

Could you write up an article about this experience with images of your subject matter. Perhaps your article would lead to others doing the sort of detailed sleuthing that you did with Zamioculcus. If you chose to write the article I would be happy to help you in any way that I can. Please tell me where is Wuppertal? I am always interested in the location of German cities since I served in the army in 1957–1959 in southern Germany and have traveled there quite a few times as well for other reasons.

It's too bad that almost nobody is on here any longer. I wonder why. Speaking along the lines of flowers, I noticed my Aglaonema "Chocolate" are flowering and the flowers are yellow. What a surprise that was. Nice change from the usual white. On Thu, Oct 24, 2019 at 10:47 AM Emily Colletti wrote: Thank you for sharing.

No on ever answered, but in private correspondence with several forum members, I learned that no one knew of pictures. Over the years since I wrote, I have tried pollinating the inflorescences. There is seldom visible pollen, so on the occasions when there is some, I have saved it in the freezing compartment of my refrigerator (not in a deep freeze). In 2018, I finally had seed. Twice. The first inflorescence was lost simply by being jarred when I moved the plant. The second, though, matured and produced three seeds. I was expecting seeds about the size and shape of olive pits, like the ones I had seen on aglaonema, but these were much bigger, rather like hazel nuts (2.76 MB photo, ZZ seeds.jpg). I photographed the seeds and planted them in whatever commercial potting soil I had then on 28 December 2018. The pot was kept in my office, which is generally 21 or 22 °C during the day and a few degrees cooler at night. On 28 March 2019, three months later to a day, I saw that one seed had sent up a shoot. Over the next few days, the others did so. The shoots didn’t look like much, but by 18 April the first had opened to give two leaflets (2.26 MB photo, ZZ seedling.jpg). These resembled what ZZ’s commonly send up from the roots. On 7 October 2019, I separated the little plants into three pots. For photos, I removed nearly all the soil (2.38 MB photo, ZZ plants with seeds-roots.jpg). ZZ surprised me again: the seeds were not being consumed to nourish the little plants, but appeared to be growing into tubers. Since I had a different kind of potting soil, I packed some of the old around the roots. I hope my naivete comes through here. Maybe no one answered my query because everybody knew all about this and assumed someone else would tell me. Maybe my ZZ seeds aren’t becoming tubers, but are doing something I don’t know about. If anyone does find this interesting, the photos are free for all to use.
