|Zaleskianum||giganteum x grandiflorum||Nat. Hyb. (no date given).|
I've got a little bit of info for you. Cymbidium x zaleskianum doesn't seem to have been mentioned by Rolfe, but there was a reference in Vol. 91, p61, which would have been 1983. It was in an article by Andy Easton (who is now with the American Orchid Society) called 'Cymbidiums, three forgotten species' and says 'Cymbidium zaleskianum (giganteum x grandiflorum) is considered a natural hybrid but it shows none of the giganteum in colour or flower form.'Isobyl, on querying this name with Dr. Phillip Cribb of Kew, got the following reply from him:
Despite Linden's comments I think that this is a synonym of C.tracyanum. It looks like the well-coloured Thai plants to me. If it is a hybrid then the only likely parentage is C.tracyanum x iridioides.Meanwhile I had written to Isobyl:
... I saw the scan of Cymbidium Zaleskianum. Without doubt this is a pure Cym. tracyanum. That of course, makes one wonder what in hell's name the Cym. tracyanum plate in Lindenia represents!! One also has to wonder why, in 101 years nobody has pointed out that Linden's plate of Cym. x zaleskianum is simply Cym. tracyanum; that is why I was wondering what you predecessor, RA Rolfe said.I then wrote to Dr. Cribb:
... As far as I am concerned the "type specimen" of Cym. zaleskianum is the icon that is Lindenia Pl.778 (1902). ... In as much as Cym. tracyanum and Cym. iridioides (giganteum) are "sister species", there is a lot of resemblance between Linden's plate and Cym giganteum, in colour particularly, and even in form to some extent. One wonders whether Mr Easton actually looked at the plate in Lindenia, or perhaps saw some live plant labelled Cym zaleskianum.
Isobyl la Croix forwarded me a copy of the e-mail you sent to her regarding my inquiry after the above plant.Dr Cribb replied:
I chanced upon a rather poor scan of the plate from Lindenia and i was immediately struck with the idea that this was simply a picture of Cym tracyanum, and i wondered why no one had commented on this in the last 101 years.
On re-examining the scan, I do notice that the lip markings along the margin are tending to coalesce into blocks. This I have seen more often in long cultivated tracyanums (Burmese) rather than plants from Thailand, and I have put it down to introgression with the sister species, Cym iridioides (which has lip-markings made up primarily of marginal blocks), which appears to be sympatric in Burma, but not in Thailand (the latter species apparently, however, growing at a higher altitude range).
Unfortunately, I have not seen Linden's text which accompanies the plate.
Lucien Linden said that the plant was imported from Assam amongst at lot of C. giganteum (C. iridioides) by the firm of Moortebeek. He thought it either a hybrid of C. iridioides x hookerianum, or a variety of C. tracyanum. I would go for the latter, although your idea of introgression from C. iridioides is possible. Without a type, however, I do not think that a firm conclusion is possible.By this point (10 July 2003), and following the surprise of hearing that the plant had come from Assam, I retired from the game for a breather.

This splendid species, whose flowers exceed in width those of all its congeners, is still extremely rare in cultivation. The forerunner was introduced a few years ago by Mr. H.A. Tracy, of Twickenham (England); amongst of a batch of Cymbidium Lowianum, with which it was readily confused, because its foliage can hardly be distinguished. Only at the moment of the first flowering, at the end of 1890, was this confusion first recognized; the plant was then shown to the Meeting of the Royal Horticultural Society of the 9th December of this same year, and there obtained a First Class Certificate. A few days afterwards, it was put on sale at the rooms of Messrs. Protheroe and Morris, in London, and was acquired by Baron Schroeder, of The Dell, for the sum of 1968 francs.
C. Tracyanum is a very robust plant, bearing many linear-ligulate, acute, leaves keeled on their lower surfaces, and of 60 to 80 centimetres in length. The scape is one meter and more long, very robust, somewhat angled, producing from sixteen to twenty flowers, which can be up to 14 centimetres in diameter. Bracts are apprimées (can't translate this, GR), narrowly oval, very acute, 1 cm long. The sepals are largely oblong, acute, about of the same length, of a pale greenish yellow, marked with a great number of stripes and small spots, of a crimson colour, laid out in nine to eleven almost continuous longitudinal lines; the dorsal sepal is erect below, with the top part strongly incurved; the lateral sepals are very spread out. The petals are almost as spread out as the lateral sepals, acute, of the same color and about of the same length as the sepals usually bearing seven crimson stripes.
The lip is notably shorter than the petals, of a yellow cream, distinctly trilobed; side-lobes rather large, erect, oval-triangular, acute, toothed or sometimes almost crenulate on the edges, marked obliquely with rather numerous crimson lines; mid-lobe longer, largely oblong, obtuse, strongly reflexed, distinctly crisped and a little cut out along the margin, covered with small closely-spaced crimson spots; disc furnished, from the base to the lower part of the mid-lobe, with two longitudinal, fleshy and densely hairy keels. Column elongated, broad, slightly curved, wingless, greenish with small red spots. C. Tracyanum is close to C. grandiflorum Griff. (C. Hookerianum Rchb.f.), this remarkable variety being illustrated in this collection (vol. IX, pl. 389), and to which certain authors seem disposed to view as a geographical form. It indeed approaches this species in form and dimension of its flowers; but it differs considerably in colour, because in its typical form, C. grandiflorum has sepals and the petals entirely of a slightly yellowish green, the lip being marked with large crimson spots. The latter has as its fatherland Nepal and Sikkim; while C. Tracyanum probably originates in Burma, the country from which C. Lowianum comes, seeing that it was introduced with the latter. Other authors are rather inclined to regard it as a hybrid, perhaps between C. grandiflorum and C. giganteum, because it almost has the very special colouration of the latter, but with flowers much larger. This assumption is far from being established, seeing that it would require that it grows naturally in the company of these two species, which does not appear probable. In all cases, it is a plant of uncommon beauty, and its great scarcity in collections is regrettable.

I grew Zaleskianum in New Zealand. It was basically a small grandiflorum. It has become much more common now because it is being collected in some area of China. I have seen it in Japan at the Tokyo Dome Show but always in the Toyoran classes (native orchids).I then forwarded a copy of the above picture, asking him if this was the flower he knew. He replied:
Yes, this is the flower I knew, providing the size is reduced about 35% from normal grandiflorum. I am sure the hybrid is natural and I think the Toyoran judging requirements allow only species and natural hybrids.I also enquired about sources of more information in the East; he replied that with the language difficulties, he could not suggest anyone.
