Vanda Roslyn Rogers

Vanda Roslyn Rogers
Vanda Roslyn Rogers is a large pinkish flower, registered in 1990 as a cross between Vanda Fuchs Indigo, and Vanda Yip Sum Wah.  However, unlike the more popular 90's cross Vanda Pachara Delight (which shares 5 out 6 species progenitors in common), this hybrid did not have the same staying power.  Searches for "Vanda Roslyn Rogers" yield few results, most of them referring to people named Roslyn.

The genealogy diagram for Vanda Roslyn Rogers is shown below.  (Link to a larger image view)
Genealogy of Vanda Roslyn Rogers
Just like V. Pachara Delight, the genealogy of V. Roslyn Rogers is dominated by two key Vanda species: Vanda coerulea and Vanda sanderiana. In total, there are 27 crossings depicted in this diagram. V. coerulea provided either the pollen or the seed in 6 of them (22%), and V. sanderiana played a direct part in 13 of the crosses (48%).  

These are the 6 species that contributed to making Vanda Roslyn Rogers.

Personally, I prefer the look of these parent species over the resulting hybrid.  However, it was interesting to see how two relatively similar family trees (Vanda Pachara Delight vs Vanda Roslyn Rogers) produced rather different looking flowers.

A classic blue orchid: Vanda Pachara Delight

Vanda Pachara Delight
Blue is a rare shade among cultivated orchids.  A few wild orchid species achieve that rare hue, but the only true blue cultivated orchid was created by genetic engineering in a Japanese lab in 2013. The gorgeous Phal has since been shown at a number of orchid shows, but don't expect to find one for sale at your favorite nursery any time soon.

In the meantime, Vandas dominate the field of the almost-blue orchid.  Vanda Pachara Delight is one such popular hybrid.  The orchid's flowers are a deep due of purple-blue, although the shade is difficult to photograph accurately.  Registered almost 2 decades ago in 1999, this hybrid is still often found blooming in stores and greenhouses.  Pachara Delight has since been used to make two more hybrids: Vanda Jan Marie Ryan, and Vandachostylis Mak Ho Seng.

Vanda Pachara Delight is a cross between Vanda Gordon Dillon, and Vanda Karulea. The whole genealogy is depicted below. (Full size image)

What stands out the most in this breeding scheme is how prominently Vanda sanderiana features in the genealogy.  There are 22 crossings in this image, and Vanda sanderiana is involved in 50% of them. Vanda coerulea, the second most important contributor to the breeding, accounts for 20% of the crosses. In fact, the primary hybrid of V. sanderiana and V. coerulea (Vanda Rothschildiana) already looks very similar to Vanda Pachara Delight.

Three other species (V. dearei, V. luzonica, and V. tricolor) contributes to the mix.

What is a phalaenopsis? It might not be what you think

Phalaenopsis display at the 2016 New York Orchid Show

What is a Phalaenopsis?  If you are an orchid enthusiast, then at first this question might seem a little too simple.  After all, the Phalaenopsis is probably the most iconic orchid.  If you search google images for 'orchid', 7 out of the first 10 image results depict Phalaenopsis flowers. It's what I first think of when someone says 'orchid'.
What a Phalaenopsis orchid typically looks like: Phalaenopsis OX Black Face 'OX 1647'

What we typically refer to as a "Phalaenopsis orchid" are the myriad hybrids that belong to the Phalaenopsis genus. This classification encompasses approximately 60 species. Also known as the 'Moth orchid' or the 'Butterfly orchid' they are a colorful, varied, long-flowering and easy-to-grow plants that are a favorite among hobbyists and breeders alike. There are more than 35,000 Phalaenopsis hybrids listed in the International Orchid Registry, and nearly 100 new hybrids are added every month!

However, over time, I've come across orchid species that bear the name "phalaenopsis" which do not actually have much relation at all to the Moth Orchid.  

I wanted to find out, just how many such orchid species are named 'phalaenopsis'? Turns out there are Four. 

Bulbophyllum phalaenopsis
Caucaea phalaenopsis
Dendrobium phalaenopsis
Miltoniopsis phalaenopsis

This made me curious about what these orchids might have in common that they all earned the same species name?  Do they resemble the Moth orchid more than other species in their genus?  I decided to briefly profile each of these "Not phalaenopsis" phalaenopsis species and see what came up.

Bulbophyllum phalaenopsis
These flowers are weird. They look nothing like the Phalaenopsis genus, and app they smell like "dead, rotting mice".  Turns out this orchid was named not for its flowers, but rather for its large leaves. This species was discovered in 1937 in New Guinea.

Caucaea phalaenopsis (aka Oncidium phalaenopsis)
Before today, I've never even heard of an orchid genus called "Caucaea". These orchids are closely related to Oncidiums.  In fact Caucaea and Oncidium are so closely related, that "Oncidium phalaenopsis" is another name for the same species. Caucaea phalaenopsis grows at high elevations in Ecuador, where it was first described in 1869.

If I squint and ignore the typical oncidium flower shape, I can definitely see how the color pattern of these flowers evokes those of Phalaenopsis hybrids.

Dendrobium phalaenopsis
This is clearly another species that was named for its resemblance to common phalaenopsis hybrids. This species goes under a number of different names, including Dendrobium biggibum, Vappodes phalaenopsis, The Cooktown Orchid, and The Mauve Butterfly Orchid. This orchid is native to Queensland Australia, where it was discovered in 1852.

Miltoniopsis phalaenopsis (aka Miltonia phalaenopsis)
This flower has almost the same color patterning as Caucaea phalaenopsis, and likely was similarly named for that reason. It was discovered in the cloud forests of Colombia in 1854.

While none of these flowers are perfect doppelgangers of the Phalaenopsis genus, they clearly do have enough features in common to explain why they were named this way.

Oncidopsis Memoria Martin Orenstein 'Lulu'

Oncidopsis Memoria Martin Orenstein 'Lulu'
Oncidopsis orchids are hybrids between Oncidium and Miltoniopsis.  This particular hybrid gracefully displays the balance between these two genera: its flowers have the full roundness typical of Miltoniopsis, yet they also display an intensity of color and pattern that reminds me of Oncidium crosses.

Oncidopsis Memoria Martin Orenstein is a 1992 hybrid between Oncidopsis Aglaon and Miltoniopsis Martin Orenstein. It's actually a slightly unusual crossing, because Oncidopsis Aglaon is a very old hybrid: it was registered in 1926.  Such old hybrids don't frequently maintain popularity long enough to still be available for hybridizing nearly a century after their creation.


Genealogy of Oncidopsis Memoria Martin Orenstein

As is typical with orchid hybrids, the breeding scheme for Oncidopsis Memoria Martin Orenstein is a bit of an overcomplicated mess. There are approximately 50 progenitors in the diagram, including 5 Oncidium species and 3 Miltoniopsis species.  

Miltoniopsis breeding clusters very strongly around Miltoniopsis Bleuana, a primary hybrid of M. vexillaria and M. roezlii. Interestingly, this orchid goes by two different names.  M. Bleuana was the first and oldest Miltoniopsis hybrid; it was registered in 1889 and named after its maker, Alfred Bleu.  However, in 1921, the exact same cross was again registered under a different name: M. Reine Elisabeth

The reason for all this Miltoniopsis interbreeding is that in the 1800s, orchids of this genus were in very high demand, but botanists' ability to hybridize them was quite limited. There were only 2 possible primary hybrids for botanists to work with: Miltoniopsis Bleuana [roezlii x vexillaria] and Miltoniopsis Venus [phalaenopsis x vexillaria].  It took another half century to discover many of the Miltoniopsis species we know today, and then more time for breeders to generate new primary Miltoniopsis hybrids in the 1990's.  Until then, overzealous Miltoniopsis breeders kept generating endless variants of the same few basic crosses.

Here are the Orchid species that went into creating Oncidopsis Memoria Martin Orenstein.  These are all a familiar list of suspects that have contributed in various combinations to most other Oncidium and Miltoniopsis hybrids I've profiled: Oncidium alexandre, Oncidium nobile, Oncidium luteopurpureum, Oncidium harryanum, Miltoniopsis vexillaria, Miltoniopsis roezlii, and Miltoniopsis phalaenopsis.

The lip coloration of Miltoniopsis phalaenopsis shows up in the final hybrid.  Likewise the purple of Miltoniopsis vexillaria comes through, as does the slightly more ruffled flower shape of Oncidium alexandre and Oncidium nobile. It remains a mystery to me what any of the other oncidium species might have contributed to this cross, or whether their traits have been effectively bred out of the orchid during the hybridization process.

Miltoniopsis Herralexandre

Miltoniopsis Herralexandre
This was one of my favorite photos from the 2016 New York Orchid Show.  The elegant flowers of Miltoniopsis Herralexandre are just beginning to open. This orchid is a 1992 cross between Miltoniopsis Alexandre Dumas and Miltoniopsis Herrenhausen.  Following a tradition seen in many older hybrids, the name of the resulting orchid is a combination of the names of its two parents.

The breeding scheme of this hybrid shows how just 3 different miltoniopsis species (M. vexillaria, M. roezli, and M. phalaenopsis) were interbred over and over again to create Miltoniopsis Herralexandre.  Here are the three species shown below.

Oncidopsis Yellow Parade 'Alpine'

Oncidopsis Yellow Parade 'Alpine'
This cheery yellow orchid is an old but still popular hybrid.  The intergenic cross between Oncidium and Miltoniopsis results in compact plants that bloom with spikes of two to five 2.5-inch flowers.  Oncidopsis Yellow Parade is a 1988 hybrid between Oncidopsis Yellow Bird and Oncidium Parade. It seems that the parents of this hybrid are no longer commonly cultivated, as I could not find images of their flowers. 

I was, however, just barely able to complete the genealogy of this orchid.  This orchid has 68 progenitors, resulting in a sprawling genealogy tree. However, in the mess that is typical of early 20th century orchid breeding, there are actually only 8 orchid species that have contributed to this cross.  On the Miltoniopsis side of the family tree, only 2 Miltoniopsis species (M. vexillaria and M. roezli) have generated 16 progenitors. 

All in all, it resulted in an intricate family tree that I encourage you guys to check it out. (the chart is much too large for the image embedded below to be legible, but it gives a scale to the breeding scheme.)
The very complicated genealogy of Oncidopsis Yellow Parade

One interesting observation revealed by Oncidium Yellow Parade's genealogy is how it is closely related to several of the other Oncidium hybrids I've profiled recently.

For example, Oncidium Brimstone Butterfly and Oncidium Golden Guinea are common progenitors for both Oncidopsis Yellow Parade and Oncostele Wildcat (which is itself a progenitor to several orchids I've written about.  The progenitors of Brimstone Butterfly and Golden Guinea account for 34 out of the total 68 orchids that went into the breeding of Oncidopsis Yellow Parade.  Essentially, Oncidopsis Yellow Parade shares about 50% of its genetics with Wildcat, Catatante and Sunkissed.

Oncidopsis Yellow Parade also contains ALL 16 of the progenitors that went into breeding Oncidium Midas.


These oncidium intergenics are closely related
There is definitely a similarity in the flower shape and general looks of Oncidopsis Yellow Parade and Oncostele Wildcat. The resemblence to Oncidium Midas is less pronounced by not completely absent.

Additionally, I have located my new record for oldest oncidium hybrid: Oncidium Wilckeanum.  This hybrid was registered in 1880!  O. Wilckeanum is a naturally occuring cross between Oncidium alexandre and Oncidium luteopurpureum.  During the late 1800's orchid enthusiasts would attempt to replicate natural hybrids by crossing the species they suspected to be parents of a given hybrid orchid.  Oncidium Wilckeanum was one of the very first hybrids to have its parentage registered and recognized (though not without continuing controversy and debate).  No one seems to grow this cross anymore, however, as I could not find any images of what this hybrid may have looked like.

Finally these are all of the 8 species that were bred together to create Oncidopsis Yellow Parade: 6 species of Oncidium and 2 Miltoniopsis.

Brascidostele Gilded Tower 'Mystic Maze'

Brascidostele Gilded Tower 'Mystic Maze'
This may be my favorite oncidium intergenic ever.  It is almost certainly the most photogenic I've come across.  Brascidostele Gilded Tower 'Mystic Maze' stole my attention at both the 2015 and the 2016 New York Orchid Show.
Brascidostele Gilded Tower 'Mystic Maze'
I absolutely adore these large vibrant flowers.  The blooms are 3.5 inches wide, on tall arching inflorescences. There are two other named clones of this hybrid, displaying variants on the color scheme. 'Tessa' is an overall lighter flower, with a cream lip. 'Thai Gold' has the brown spotting of the main petals extend all the way out to the tips.

Brascidostele Gilded Tower is a 2005 cross between Brassostele Summit and Brassidium Gilded Urchin.  The full genealogy, a fairly simple one, is shown below.
Genealogy of Brascidostele Gilded Tower
Four orchid species, from three different genera have gone into the creation of this hybrid: Rhynchostele bictoniensis, Brassia keiliana, Brassia arcuigera, and Oncidium wentworthianum.  Here is what they look like:

I wonder who came up with the naming for a Rhynchostele/Brassia/Oncidium intergenic-- 'Brascidostele' is such an awkward mouthful of a name.  The crossing makes such strikingly gorgeous orchids that I wish it had a prettier name to grace them with.
