Dendrobium lindleyi
Submitted by papillon on Mon, 01/09/2008 - 13:42
Dendrobium lindleyi Steud., Nomencl. Bot., ed. 2, 1: 490 (1840).
I have had this orchid for three years. Bought in bloom it then did nothing until flower spikes appeared in early August 2008. Very slowly these extended until it burst into bloom on 28 August. This orchid seems to be widespread in S E Asia and apparently needs a dry season to bloom well. I tried keeping it dry in 2006, and 2007 but changed this in 2008 and watered it throughout the year. It is very slow growing.
Nice display
They do put on a nice show!!!!!!!

Dend. id
Hi Bill,Is this not Dend.aggregatum......correct me if i'm wrong.I'm a bit confuse within these two plant.Thanks in advance for the info.
Pak sheikh.
Den. ID
I tend to agree with pak sheikh, D.aggregatum has longer stouter psuedobulbs and is more floriferous, like the image shown.
D.lindleyi, which is very similar, has fewer, paler yellow flowers

The accepted name for this plant is Den. lindleyi synonyms Den. aggregatum and Den. aggregatum var. majus.
The habitat for this plant is wide spread so of course natural variation in height of bulb and flower size can be expected.

Hey Bill...
Cattaleya's I know a little about, Den's nothing,,,I have lindleyi and aggregatum growing side by side, they are different in growth habit and size,,,,so are you saying that they are both lindleyi or what,,,this synonyms thing leave's me dead, can you explain what it means for us beginners out here please...Thanks Warren and Karen
Yes that is correct.
Yes that is correct. Take for example comparing the physical sizes of Dendrobium speciosum var grandiflorum with Dendrobium speciosum var pedunculatum. Also consider the huge variation in flower qualities in populations of Dendrobium speciosum. Its the same with D. lindleyi.
D. aggregatum is no longer a valid name they are all now D. linleyi since it was the first published valid name.

dry winter rest
These definitely require a dry winter rest to flower reliably papillon. I find that they flower best when grown in high light conditions and must be protected from winter rainfall if at all possible. I give them a very brief spray maybe every 2 or 3 weeks over winter and don't stress too much when you notice they have shrivelled a little....they will benefit from that and reward you with prolific flowers.
Regards wellsy
oh,,,ok
So that is why mine arn't flowering, they live with my Catt's and get treated the same way,,,,Lesson learn't

Dry winter rest
Thanks Wellsy. Generally my natural "winter" weather (in Far North Queensland) is fairly dry and around 20-23 C from June through to August) But in 2008 I included D.lindleyi in a regular watering programme as I was disappointed in its lack of performance in the two preceeding years. I think now that I kept in too dry too long in 2006 and 2007. Now it lives in my shade house and looks much happier and I will more careful with it from now on.
If we knew more about from where our particular specimen's parent plant originate that might be helpful too. Otherwise there is a lot of hit and miss in respect of plant species from widely different and diverse habitats. Always something new to learn!

D.jenkinsii
I really should look up current names before submitting material for discussion. I thought that D.lindleyi was the new name for D.jenkinsii. Obviously not. I believe that the image shown is D.jenkinsii which is of a smaller stature than D.lindleyi. Also D.jenkinsii has far fewer flowers.bernabu
maybe
Yep....it could be D. jenkinsii but I think a more detailed photo would be required to confirm that Bernard. One distinguishing thing about Dendrobium jenkinsii is that it tends to flatten the psuedobulbs against the mount.
Compare to this one here http://orchidsonline.com.au/node/2773 but this photo does not really show enough plant detail either.
EDIT: This one has better plant form detail I think http://orchidsonline.com.au/node/4078

D.lindleyi
wellsy, I think that the image you posted of jenkinsii shows clearly that papillon's image of lindleyi is correct. The main difference I see between the two species (besides the difference in plant size) is that lindleyi shows branched inflorescences and jenkinsii doesn't.
bernabu
brilliant
your brilliant Bernard! Seriously I had never noticed that.

lindleyi or jenkinsii
Den. lindleyii flowers from nodes at the middle of cane.
Den. jenkinsiii flowers from near the base of the cane.
All we need is Papillon to have a look at where his spikes are coming from.
Bill
flowering type
The flowers erupt from the cane about 15mm from the point where the leaf begins and are on branched inflorescences, in my plant's case averaging 12 flowers per stem. The flowers are alternate on the flowering stem. The canes are around 6cm long; the leaves are around 12cm long. The lip of the flower is 32mm.

Good news!!!
Thanks Stephen, that info tells me your plant is Den. lindleyi without a doubt.
