Phal. venosa
Phal.
venosa is a relative upstart in the history of Phalaenopsis. Discovered
around 1980 and only really introduced into cultivation in the
mid-1980s, Phal. venosa was originally known as Phal. psilantha (and
awarded as such). This name was difficult to change and, for a time,
there was such confusion among hobbyists that some believed that that
these were two distinct species. (Culture note: many people give
this species less light than other Phalaenopsis that they grow.)
As
with several species that are intense yellow, some judges were intensely
enamored with this "new" species, accounting for the number of
awards. We now recognize that the best flowers of Phal. venosa for
breeding yellow are those that are deep yellow or yellow-green and
almost solidly overlaid with brown or mahogany coloring. Originally,
many people believed that the greener the flower, the better the plant
for breeding regardless of the amount of brown/mahogany overlay.
Floriferousness, and especially size, can vary widely among the good
clones: for example, the original C.B.R. plant shown in Florida in 1982
had 2 flowers on 1 inflorescence and was 4.0 cm. but the natural spread of the awarded flowers
go up to 4.7 cm.
With
the exception of 1994 and 1996, there has never been a year in which
more than 20 Phal. venosa hybrids were registered. The first hybrids
made with Phal. venosa were only registered in 1984, 15 years ago.
Several hybridizers remade many hybrids that had been made with Phal.
amboinensis. Others struck out in new and different directions. However,
many people now freely admit that breeding with Phal. venosa can be
difficult and that, while Phal. venosa hybrids can be very attractive,
breeding with some of them is nearly impossible. Phal. Zuma Aussie
Delight (Sweet Memory x venosa) has been meristemmed and is in hundreds
of collections. Despite this fact, there are only a couple of registered
hybrids and hundreds, possibly thousands, of failed attempts.
Phal.
venosa was used in making several primary hybrids. One of my favorite
hybrids is Phal. Kuntrarti Rarashati (x Phal. equestris), registered in
1986 by A. Kolopaking. Its use in hybridizing has only just begun. (The
first hybrid was registered in 1995.) The nicest multflora I have ever
seen was a Phal. Taida Pixie (x Phal. Carmela’s Pixie) at an orchid
show in Taipei in 1997. The hybrid Dtps. Pico Lady Ruby was registered
by Brother Orchid Nursery in Taiwan in 1995. The hybrid was re-made just
shortly afterwards by Ed Merkle. His cross resulted in several AOS
flower quality awards and an Award of Quality to the proud
breeder-exhibitor. To date, very few hybrids have been attempted but a
cross to Phal. Mahalo has produced seed. Another hybrid of Phal.
Kuntrarti Rarashati, Phal. Little Yellow Ball (x Phal. amabilis)
produces very floriferous, multi-branching inflorescences bearing
peach-colored flowers.
Ooi
Leng Sun registered Phal. Penang Girl (x Phal. violacea) in 1984. The
hybrid has been used about 10 times in making registered hybrids.
However, in much the same way that many Phal. amboinensis hybrids were
remade using Phal. venosa, you can expect that Phal. Princess Kaiulani
hybrids will be remade using Phal. Penang Girl. It is not very
floriferous but a large adult plant will rarely be out of bloom. It is
both colorful and fertile, a wonderful combination. A delightful
fragrance is an added bonus. Expect Phal. Penang Girl to be a very
important hybrid now and in the future.
Another
primary hybrid, Phal. Ambonosa (x Phal. amboinensis) was registered by
A. Parnata in 1984 and has been used extensively in breeding. There are
four awarded clones to this grex. Flowers range from about 4.5 to 5.5 cm
natural spread and can be quite plentiful. It is the parent of about 30
registered hybrids to date, having been used since 1989. Most of its
hybrids to date are hardly known but Phal. Minho Queen (x Phal. Paifang’s
Auckland) has one award and Phal. Brother Torro (x Phal. Peach Boy) has
several.
The
hybrid Dtps. Jim (x Dor. pulcherrima), registered by H.P. Norton was one
of the first Phal. venosa hybrids, registered in 1984. Despite the
elapsed 15 years since this hybrid was registered, only 3
first-generation hybrids have been registered to date, and only since
1995. There are no second-generation hybrids. Similar Phal. venosa
hybrids registered in 1986 and 1995 by H.P. Norton, Dtps. Tony (x Red
Elf) and Dtps. Shadrach (x Dtps. Inferno) are each the parent of only a
single hybrid.
In
1984, John Miller registered the first hybrid of Phal. venosa with a
large white (Phal. Mem. Anton Smith) as Phal. Bob Gordon. This hybrid
received 7 AOS awards and has only been used 9 times in further
breeding. Phal. Taipei Gold was also one of the first Phal. venosa
hybrids (x Gladys Read), also registered in 1984. There are 8 awards to
different clones of Phal. Taipei Gold, most of them from the first time
that this hybrid was made. But the plants proved difficult, if not
impossible, to breed with. Many people thought that they might be
triploids, the result of crossing a diploid Phal. venosa with a
tetraploid Phal. Gladys Read. The cross was remade several years later
using a known diploid Phal. Gladys Read and the results were very
different. The ‘Gold Star’ clone was set aside and has now gained
wide distribution. It - and, presumably, other clones - have been used
to make about 60 hybrids to date, many of them in Taiwan :
first-generation hybrids include Phal. Brother Lawrence, AQ/AOS, Phal.
Brother Passat, AQ/AOS, Phal. Brother Victory, Phal. Brother Gold Miss,
Phal. Sogo Chin Chien, Dtps. Sogo Manager and second-generation hybrid,
Phal. Taida Lawrence, AQ/AOS. Almost all of these hybrids produce large
yellow to (generally clear) yellow-green flowers, relatively large and
reasonably floriferous.
Phal.
Golden Bells (x Phal. Golden Sands), a hybrid registered in 1988 by H.P.
Norton, is possibly the next most prolific Phal. venosa hybrid. It has
received three awards to date and is the parent of approximately 40
registered hybrids to date. Considering the relative youth of this grex,
it has already begun to prove its worth with several of its
first-generation hybrids such as Phal. Orchidview Bellringer, Phal.
Melodious Bells and Phal. Golden Circles but, yet again, it is much too
early to examine the complete impact of this grex.
Another
Phal. venosa hybrid, Phal. Pago Pago (x Phal. Lippeglut) is possibly the
biggest disappointment in further breeding. This grex was registered in
1988 by Zuma Canyon Orchids and produced incredible art shades on very
floriferous plants. They caught the eye of many a judge which accounted
for the high number of awards to this grex. However, there are only
about a handful of registered hybrids to date.
Phal.
Francis Melendez (x Phal. Bamboo Baby) is another well-known and
well-distributed hybrid of Phal. venosa. Despite 15 awards to Phal.
Francis Melendez, it is the registered parent of less than 10 hybrids to
date.
There
is a group of Phal venosa hybrids that can best be lumped as
near-primary hybrids. There are many of these including Phal. John Ewing
(x Phal. George Vasquez) and Phal. Venimp (x Phal. Malibu Imp) in the
United States and Phal. Coral Nosa (x Phal. Coral Isles) in Taiwan. The
flowers in this group all tend to be quite dark, star-shaped and few in
number. However, they are all fragrant and relatively new to the
hybridizing world. Of these, Phal. Coral Nosa has probably been the
plant that has been used the most in hybridizing. It is the parent of
Phal. Black Eagle (x Phal. George Vasquez), Phal. Chiayi Golden Moon (x
Phal. Maritea), Phal. Ta Lin Kaiulani (x Phal. Princess Kaiulani) and
Phal. Black Beauty (x Phal. gigantea).
As
usual in yellow breeding, it’s too soon to give definitive comments.
Let’s wait five years – until we have a better idea of the lasting
impact of Phal. venosa.
The opinions expressed in the plant of the month
articles are those of Howard S. Ginsberg and are based on various
discussions, observations and research which includes American Orchid
Society Awards by James R. Fisher and David A. Bishop (available from
the American Orchid
Society) as well as the Wildcatt Database (available from the Wildcatt
Database Company). The Wildcatt Database may not be perfect but it
is far and away better than whatever is in second place.
