This is the first bloom of the season...with over 150 buds on the plant! Should be quite a show!

Please check out entries below, the identification on this is multi-layered...and very confusing!

150 buds--wow. Can't wait to see that.

I was given a well-established mounted plant...and smaller seedlings separately...by a dear friend (who sadly is no longer with us) who didn't have tags on the plants. He said they were both Den pierardii. I mounted the seedings on a grapevine wreath and attached the small treefern plaque with the established plant to the center of that wreath, thinking it would be a heck of a show when they all bloom at once.

Well...my first post in this thread shows a bloom from the smaller seedlings mounted on the wreath. I called it Den pierardii and said the plant had over 150 buds on it.

In the past few days, the buds (on the more established plant) have started opening and there is a stark difference between the two. These are smaller and the throat is more white with very little in the way of purple markings.

I've spent some time researching this and I've come up with the following:

The original picture posted, with the larger bloom and darker throat markings is Den pierardii v. cuculattum

The picture posted below, smaller in size and more white in the throat is Den aphyllum.

I've also added another photo of the original bloom and a photo of the two blooms side by side so you can see the size difference.

Can anybody here shed some more light on this for me? It's SO confusing!!!

Wow! Sue! That's amazing!

I have no idea about the flowers or the plants.... only that they look really good

Thanks Niki

I'm hoping somebody here can educate me on this one

What I have found is that -
Dendrobium aphyllum is syn. to Dendrobium pierardii = to your photo #1
and ...
Dendrobium cucullatum is syn. to Dendrobium pierardii var. cucullatum = photo #3
but then I have also found this -
"Dendrobium pierardii Roxburgh -- as D. aphyllum (Roxburgh) C. Fischer
Dendrobium pierardii var. cucullatum (R. Brown) Hooker f. -- as D. aphyllum (Roxburgh) C. Fischer"
(as per Sheet List- Dendrobium )

so it's a big roundy round loop ..

siting 2 different looking species as one
I'm just as confused
