Mine is called crepidiferum. You can have a little fun with jay Phal's site. Look up crepidiferum and glomerulatum. He uses the same photograph for both sites, calls one a synonym for the other but labels one a warm grower the other a cool grower.

I grow mine cool but they'll grow at any temperature. The flowers have a strong color and last forever. Your 4 bunches should make a beautiful display.

Lovely, strong coloured bloom.

I actually have 2 of them, that I think are 2 different varieties - this one has strictly upright, relatively thick canes, and the other has thinner, horizontal to pendant canes, and smaller, but otherwise identical flowers. Hard to know for sure, but the thinner one also seems to like lower light and higher temps. Crepidiferum, glomeratum, and sulawesii - maybe one day we'll see if these are all the same.
