That is not a zeylanica. Zeylanica is a species. That is S. t. ‘Robusta’, commonly but incorrectly called zeylanica. It stays about Futura size.

Oh! What does a real Zeylanica look like? Seems I can only find pictures that looks alot like the one I bought.
Strange that they are so often sold as Zelanicas then, had the nametag on the plastic pot it came in aswell.

This is zeylanica according to Juan Chahinian’s book.

Thanks Lori, Bob Smoley's picture looks a little different but still looks like trifasciata.

Thank you Stush and Vitorama. Funny (or not) how the name could get so mixed up haha.
Here is a pic with my new "Zeylanica" to the left and Robusta to the right. I think they look very different from eachother though in shape and colortones even if both are Robusta. The left one doesn't have a single leaf as wide as the right ones and more swordshaped. Sans are interesting ^^

There are so many cultivars of trifasciata, it’s incredible. I just saw an ordinary pot of laurentii but on closer examination, one plant in the group had thick yellow stripes down the center of the leaf! Like a racing stripe. I bought the plant(insanity) and separated out the racing stripe plant to see if it will continue to grow that way. I’ve got my fingers crossed! But chances are, it will revert to regular laurentii.

Lori, Good eye. That's exactly how new cultivars are brought out. I think under further screening, and elimination, you could end up with something special. I too did such a thing with a extra stripe on a Compacta and currently watching something different going on. Did you ever see a leaf with more than one point? While as a young rhizome pushing on the side of the pot, seems several leaves grafted/morphed into one strange leaf having much more yellow than normal.

Notice the ripped leaf, thread shows where leaf was together at one time. When tried to pull apart, found the leaves were all one with parallel growths and several leaf points. Started with a mother plants just like the one you got.

That is the strangest leaf I’ve ever seen, Stush! I can’t wait until it grows out more. I hope you have a cool new cultivar.

Thanks Lori. Time will tell but already love the wild variegation in leaf. New inner leaf looks to have similar variegation. Inner and outer variegation of leaf differs. Inside shows a narrow green center stripe with extra wide yellow while outside show almost regular pattern but with extra yellow stripes randomly.

Hi Stush, i have a couple of leaves that have gone a little wild too. My sister grew this plant and it was way overcrowded, maybe that caused the leaves to grow together. This is another leaf attached to the back of the large one. The tiny one in the lower picture is partially attached. Strange!

Beautiful markings on that leaf. Mine was also over crowded as well. Possible that started the strange happenings.

Wow, those are all so cool! Definatly gonna keep my eyes open for plants that has "strange" leaves.

It looks like I have the same S. Trifasciata as EB88 is talking about. If EB88 means 'more yellow' with 'new Zeylanica' that is. I'm not sure since it seems that a flash is used while taking a picture. But I'm not sure EB88 is also talking about this yellow tinge though ...

But nonetheless, see picture below. On the right a S. T. 'Black Coral', in the middle a regular S. Trifasciata, on the left a regular S. Trifasciata which seems to be more yellow than a regular S. Trifasciata. They are both grown with the same lighting conditions and I always assumed the yellow would correct itself to the regular S. Trifasciata. But it does not. It keeps being more yellow and is a really slow grower also. Overhere it is sold as a Sansevieria 'Green line', which apparently is made up. Our regular S. Trifasciatas are sold as S. Zeylanica.

@barbmock: I've also seen this behavior from my S. 'Midnight Shine'. Overhere sold as S. 'Black Gold'.

Love that Midnight Shine!

When I bought it I didn't care too much for it to be honest. Just had to have it. But it turns out to be a really nice plant. Short, thick and wide leaves. My widest one is 12cm, (5") already with a total height of about 24cm (10"). It also produces really, really fierce and pot breaking offsets. This is truly one of my strongest survivors in my collection. It just pushes itself out of the container, pretty funny actually.
