Dendrobium agathodaemonis

Hi Marni, I missed that comment earlier! Yes...it's all clear now. If cuthbertsonii is dominant in crosses (as a friend of ours not on this forum states), then if agathodaemonis was a hybrid with cuthbertsonii it would most likely have some "hair" on its seed pods. I'll let him know what I picked up on this forum, but if he doesn't listen, you might have to persuade him.

 

Richard Warren only produced the red as far as I know. To my knowledge there are only pink and red colors(though I have seen a slight bicolor of pink/white). Andy has around 20-30 pink ones. They are all about the same size, so this leads me to believe they are seed grown and consistent. I'll be sure to ask him.

 

Is it still in bloom?
Have a curent pic.?

 

LAST YEAR!!!!
Holy cow!
Cooooooooool!!!!!!

 

What is the red flower in the pic.?

 

Wow, keeps getting better!

 

Update on mine...a new flush of blooms. The shape is not as nice as yours Mikhail, but when fully expanded, they are quite large. One photo shows an older bloom from January.

 

Thanks Mikhail, maybe we should try reciprocal outcrossing sometime?

 

I have sowed and raised several batches of "normal" cuthbertsonii x "agathodaemonis type" (they cross very easily for me), they are quite vigorous, and very intermediate in plant shape. the flower still lacks the brown lip bar, but has a yellowish zone instead.
I also have raised batches of agathodaemonis x agathodaemonis, and the seedlings look pretty homogeneous, nothing like an hybrid would do!

 

Well, I tried with red/yellow bicolor cuthbertsonii (pink-white agathodaemonis), and the result, so far, as been pink or pink + white petal tips. not a trace of red-orange.

 

mmmhhh don't expect much of "breeding line" there. some 3-4 years ago, Popow managed to import heaps of collected plants, all in the pinkish-white shades. Most probably some of those went to USA. I haven't yet heard of commercial seedlings production of this type of agathodaemonis.

 

I usually go by Kews World Checklist of Plant Families (Monocot List) and in there it states that Den agathodaemonis is a synonym of Den cuthbersonii. I go by this site some people don't.

Hello pacome, Do you know of anyone in Europe who is trying to propagate the red form? I remember seeing photos.

 

Beautiful blooms, congratulations!

Because of the way species get introduced into horticulture, we don't always see the morphological diversity of a species present in its natural range. Dendrobium cuthbertsonii has a large geographic range and is super variable not just in flower colouration but also in the texture, colour, shape and dimensions of its leaves and pseudobulbs.

What is in cultivation as agathodæmonis is an extreme of natural variation. There may well be populations of agathodæmonis-like plants in the wild that in cultivation come true from seed, but one population does not necessarily a species make. I have seen a number of cuthbertsonii of natural origin that contradict the characteristics cited in this thread: smooth pods on wide-leaved, marked-lip plants, marked-lip flowers on 'agathodæmonis'-type plants, plants with foliage and pseudobulbs that are perfectly intermediate between 'agathodæmonis' and cuthbertsonii.

For horticultural purposes the agathodæmonis term is useful as a qualifier but not as an official species name. I label those that fit the agathodæmonis extreme as: Dendrobium cuthbertsonii (agathodæmonis strain).
