This was originally diploid, but one of the clones selected by Geyserland Orchids was 4N and became Orchid (Cymbidium Red Beauty 'Geyserland Netty') (later used for NHO hybrids such as Orchid (Cymbidium Kirby Lesh)).

This species has two forms - the Indian form, which only ever has one or two flowers, and the Vietnamese/Chinese form, which can have three. The latter form is often confused with the natural hybrid between eburneum and mastersii - Orchid (Cymbidium x ballianum) - due to its flower shape being more rectangular (like ballianum) and a little smaller than the Indian form of the species. Any 4+ flowered so-called eburneum will be ballianum.

This natural hybrid is often confused with Ivory-Colored Cymbidium (Cymbidium eburneum), especially as the Vietnamese/Chinese form of eburneum is known to have 3 flowers and has a shape that is closer to ballianum than the Indian form of eburneum. If you see a 4+ flowered "eburneum", it is ballianum!

This has been used in a number of crosses within Australia and is known to produce compact offspring, despite its large foliage.

This is a recently-discovered species (early 2019) first published under the name Cymbidium yunnanensis but then changed to Cymbidium dianlan due to the first name being illegitimate under existing ICN rules. It is similar to Golden Leaf-Edge Orchid (Cymbidium floribundum) but phylogenetic studies support its classification as a separate species.

Registered as a cross of Cym. floribundum with an unknown plant. However, hybridiser Andy Easton recalls that it was known at the time that Oiso was a Japanense hybrid of Cym. floribundum and Cym. Pauwelsii. The grex itself existed as both diploid (2N) and tetraploid (4N) versions. A 4N plant was used by New Horizon Orchids in several hybrids.

This is a known tetraploid (4N). Andy Easton has been pleased with the results of this cross and suspects penduluous whites could be produced from this specific plant. He has left it with a fellow hybridiser to use.

This is a known tetraploid (4N). Both the plant and blooms are classified as miniature and it has been used as both a pod and pollen parent by Andy Easton of New Horizon Orchids in his breeding programme.

This is a known tetraploid (4N) and selected as the best of the seedlings produced by New Horizon Orchids for cloning. It has 25+ flowers per spike, clean foliage, fragrance and warmth tolerance.

This is a known tetraploid (4N) from the remake of the grex by New Horizon Orchids.

There is a Phal hybrid called OX Surf Song in commerce that is almost certainly this grex relabelled. Photos of the two are very similar and some of the Surf Song clones include "OX" in the name.

This is a known diploid (2N).

This is a fertile plant and believed to be 4N (the result of 3N x 2N cross). It produces numerous spikes of 5 to 7 flowers.

This is a known triploid (3N) and a fertile pod parent. It has been used by Andy Easton of New Horizon Orchids.

The registered name suggests that this grex was originally made using Orchid (Cymbidium Rincon 'Clarisse').

This is a known tetraploid (4N) and is one of Andy Easton's breeding plants.

This plant is probably one of the more famous and most hotly debated Cymbidiums in existence. This is the type for the species, collected as an epiphyte in 1904. It was thought lost from cultivation until 1961 when Emma Menninger located it in a nursery and had it cloned. Don Wimber later converted it to a tetraploid (see Orchid (Cymbidium sanderae 'Emma Menninger')) (Du Puy & Cribb, 2007).

It was called Cym. parishii var. sanderae until 2001, when it was renamed Cym. sanderae. This has lead to some confusion in the RHS Orchid registry, as many hybrids made with this plant were registered as having Cym. parishii as a parent.

The plant itself is unique, exhibiting behaviour that differs from other plants classified as Orchid (Cymbidium sanderae). Andy Easton has selfed both the 2N and 4N forms (the aforementioned 'Emma Menninger' clone) and produced seedlings that varied considerably, often with green blooms. He regards it as a naturally-occurring hybrid involving Ivory-Colored Cymbidium (Cymbidium eburneum) (due to its ability to produce concolour lips, a trait that eburneum is known for). He discusses the matter at length in a few posts on the New Horizon Orchid forums (which are reproduced in the book Cymbidium Orchids: Secrets Revealed by Graham & Sue Guest with Andy Easton).

Additionally, this plant produces both axial and basal flower spikes (as opposed to Orchid (Cymbidium parishii), which only produces axial spikes, and Orchid (Cymbidium sanderae), which has been reported to produce basal spikes).

Grieg Russell (2003) has also selfed it and found it has a level of self-incompatibility - it does not produce a full pod of seed, unlike Cym. eburneum (which is highly self-fertile).

This is a tetraploid (4N) F3 tracyanum produced by New Horizon Orchids and is one of the best alba forms of the species currently available. Clones were made available in Australia in 2019 by Guest Orchids.

This is a selection from the 4N F1 tracyanums produced by New Horizon Orchids. It was marketed somewhere around 2000 by Mukoyama Orchids. Unfortunately it seems that the clonal process wasn't up to scratch in this case and that the clones mutated, resulting in quite a few reports of them being difficult to bloom.

This is one of the few tetraploid (4N) seedlings that resulted from a treated cross made by Andy Easton in the 1980s. It has been a parent in one of his Cym. devonianum hybrid lines, producing Orchid (Cymbidium Arthur Medellin Padilla) and Orchid (Cymbidium Devon Cherry) (which has its own offspring now as well).
