Maimiti,
The easiest way to tell is from the leaves. Nobilis has serated leaves (edges). It also has a distinct form at the tip of the leaf which can not be seen on your photo (a sort of rounded tip). Can you post a photo of the the leaf tip? Nobilis is also the slowest grower of all Clivia species but a valuable part of any collection. It is often used in hybridizing.
Yousrs is a beautiful colour!!

Dries,
This is a fast grower. Actually, all my Clivias grow extremely slow exept for this one. It has about 10 babies now but that is what it has produced for 3-4 years. I gave all the previous babies away a few years ago and that was about 10 that time too so it reproduces readily. I have another Clivia that I recieved as C. caulescense and it hasn't grown a bit since I got it two years ago.

Attatching photos of the whole plant and leaf tip of C. nobilis (?).

I think this is a Gardenii defenitely not Nobilis. See the link I posted on the Clivia Species earlier today.
I maintain that the flower colour is special!!

Thank you Dries,
Yes, I looked at the link you posted earlier and I bookmarked it too as I really liked the site. Lots of useful information.

The color of these flowers are very nice and I've actually not seen them elsewhere. I don't know if the color is due to growing conditions. I've always had the plant in a window facing north. It's also the only one of my Clivias that flowers regularly, most of them don't flower at all, but I've always been hoping for more dense umbels.

I found a website with some Clivias, unfortunately it's in Swedish but the photos are international ;) Anyway, there is a Clivia caulescens there that actually looks a lot like my plant.

Here is a link that might be useful: CLIVIA CAULESCENS, ART

That is a fabulously coloured gardenii, the nobilis has a notched leaf as Dries indicated, I have also found them to have a larger number of flowers

Here are some pics of 'Wild nobilis'
