I found 3 more Dendrobiums that might be good for the list. I missed them before because they have some interchangeable names.
For those who wanted aggregatum (lindleyi), there is a smaller version of this plant that does not need as cool of a winter rest.
Den jenkinsii (was known as Den aggregatum var jenkinsii, but is now classified by itself)

I looked it up in my two Dendrobium books and AOS for additional information. The highest CCM award (93) was in 1975 and the total size of the plant with 400 blooms was 40cm (15.75"). So it is really a compact orchid.
According to Dendrobium and its Relatives "This is a miniature, creeping species closely allied to D. lindleyi but it is considerably smaller in its vegetative parts." Grows from 500-2000 meters altitudes. "Plants flower in spring and are best cultivated in intermediate conditions. Because of their creeping habit, they are more amenable to slab culture than to growing in a pot. A distinct drier winter season is recommended."
My other book, The Dendrobiums, describes them as an intermediate grower that doesn't like to get too warm or too wet. Needs dry winter rest and high light.

The 2nd Den is glomeratum (aka sulawesiense). Some growers haven't updated their labels so these two can be interchangeable. Here is the data.

My book has glomeratum listed as small to medium sized. Culture intermediate. Does not thrive in cool conditions and intolerant of drying. (needs humidity) It is similar culture to lawesii.

And the last one I found is one I have been wanting a long time.
Den harveyanum

Culture is intermediate. It does require a dry winter rest and I am told at a cool temp but not cold. It looks very interesting for a project plant. The largest awarded in AOS was 40cm tall inflorescence (15.75").
