Dendrobium confusion

[dons]

Hi group!
I have a question concerning the different types of Dendrobiums. The question deals not with the flowers (That will come later), but with the plant growth pattern itself. I have three plants, two with multiple leafs on each stem and a third which appears to have a single leaf on each stem.
Are these different types? And if so which?
Thanks in advance for your help ..... dons

Well, to my novice eye, the second photo appears to be a cattleya alliance plant, not a dendrobium. Did it come with a name?

I agree, #2 looks like some kind of Catt. #1 is a Phal type Den. They like to be grown warm, plenty of water, fert and light. The do not require a winter rest period like some Dens do.

Hello Dons,

I have a Dend. whose plump pseudobulbs look similar to yours. Mine is a Den. Spectabile and it is a species and exhibits 2 leaves atop each pseudo. This is my first species type den. and I'm no expert, but perhaps you have another variety of Dendrobium species that produces only 1 leaf. There are soooo many varieties out there. Maybe some of the OB experts will chime in with their opinion. Here is a photo of mine for comparison.
