[Aroid-l] Monstera tenuis in cultivation.

From: gartenbaureisenberger at web.de (Helmut Reisenberger) on 2008.07.04 at 00:39:29(18064) It is about five years ago that I found a well developed, adult species of Monstera tenuis in the Botanical Garden of Darmstadt (Germany). It didn?t have a name tag and nobody could tell. I got a stem cutting with two internodes and adult leaves. After I have cut the stem into two pieces (each nodium) I sterilized it and put it into a cup of fresh water. As soon root tips developed after two weeks, I put the cuttings into a cup filled with sterile, washed coarse river sand. There it took a while until new shoots showed. The result was: a stem of one millimeter diameter, very long internodes and tiny, round, juvenile leaves. The stems grew for several meters, but the leaves did not get any bigger. I cut the stems again and again and each new cutting produced the same type of new shoots. Over the years now, the oldest plants have a stem of 15 millimeter diameter and still the same type of round, juvenile leaves up to 20 cm diameter. I think it needs time and the right growing conditions to produce adult, spl it leaves as well as shorter internodes. I never had problems with rooting any cuttings,- like I hardly have problems propagating different Monsteras under "Central European greenhouse conditions". I am about to make a picture documentation of my different Monsteras (with a lot of ID- questions directed to the forum). I wish I had more time to do it. I?ll be back!

Mike Madison had quite a collection of Monstera taxa but when he left in 1983 most of his collection was distributed to whoever wanted it. At this same time I was faced with a 3200 sq ft loss of growing space so the loss of a few big aroids wasnt one of my top concerns. We do maintain a synoptic collection of Araceae but because we have no one on staff working with the family its down to ca 800 sq feet of greenhouse bench space. Over the years Ive heard all kinds of stories that we no longer have aroids. Visitors know otherwise.

Perhaps our mutual friend Harry Luther can investigate and let us know if this plant still exists there, and if so in what condition? By the way, it is one of the Monsteras which has a pinnatifid leaf blade. > If this species is so very difficult/impossible to grow from cuttings, and IF it is still in Selby`s collection as an adult plant, and IF it blooms, I`d GUESS that, like my M. deliciosa, it produces large seeds, and seeds = plants! > You see what a ''leap of faith'' I take here! Maybe Harry can investigate this angle and let us know??? > Another possibility is to learn it`s range in the wild, and try for seeds from there. We know it occurs in Costa Rica, as that is where Craig made his collection of cuttings. I wonder what it`s range is in that general area, if if perhaps it extends into Guatemala?? > > > Aloha, > > Julius > > > > > Dear all...especially Julius, > > > > Aloha...and good to hear from you. > > > > I knew you would know about Craig Phillip's article...what a computer for a brain.
