Which group?
 

Thank you for answering me. I probably am ignorant, so which of those 6 groups does my plant belong to? Thanks! Greg.

They do not belong to any of the 6 listed groups. Again, the 6 groups is a dated method of culture and what we have available today , oft does not fit in any group.

The Aussies all like lots of light, some full sun, and, when in growth, lots of water. They do rest, but not based on the month, rather the availablility of water. Most of the D. kinginaum and its hybrids like to get dry for the Winter, but cooler temps are a must for bloom. Mine are in the garden and stay out there until close to freezing temps. If we have a week of cool nights in Summer, they bloom again. Generally they bloom in late Winter to Spring, after being kept around 10°C. for 3-6 weeks. When in bloom keep them just moist, as too much water will make them drop their blooms prematurely. They think the rainy season is starting!

Zhuhai may be too warm for the kingianums to do well. D. speciosum and tetragonum are more warm tolerant as is the closely related canaliculatum (spathulata type).

my kingianum/delicatum noid
 

Firs of all-- thank you so much for the valuable info. It is great information for me. By the way, I think that my noid plant does quite well here in Zhuhai (LOL). I have attached some pics. The pics in bloom were from late winter (March). The pics without blooms are quite recent. I don't know if you can tell from the pics, but the plant has grown considerably and is so healthy! I wish I knew the ID-- that info I probably will never know! I have been told by someone that it definitely is not a kingianum. The Chinese lady that sold it to me only could tell us that it is Australian. (My wife speaks Chinese, so she could communicate with the seller).

Again, thank you!

Well, if they bloomed once, it should be possible to repeat. It could be a speciosum-kingianum hybrid, which strongly resemble kingianum, but are easier in warm climates. Speciosum tends to extend the spike length for mature plants, as well as increase bud count. I have a couple of these and they are generally heavier plants, not so long-bulbed as pure kingianum. Still, at a glance there are few differences.

I read what the categories were, and I didn't feel like the descriptions really captured what the plants you were asking about really were, so Regelian was right in responding the way he did.

I answered in a way that I understood the orchids to be.

Thank you for the information.

Where is the chart?
 

I have 3 dendrobiums and I would like to be able to classify them by group, but I don't know where to find the chart referenced in this post. Help!

I have the hybrid names as well as the parents, but that doesn't help since I don't know where to start looking

I don't understand... D. speciosum and D. aggregatum are not deciduos!

Thankyou this is very useful for my Noble now I know what it is!
