Tiger Morning seedlings

Below is one of three siblings from the cross Cym ((lianpan X lowianum), 4N X Tiger Tail, 4N), purchased from George Hatfield back in 2005. The other two are in spike, but not yet open. I'll update this post when they come into bloom.














Natural Spread: 5.7cm horizontal, 6.5cm vertical
Lateral Sepal: 3.6cm length, 1.1cm width
Petal: 3cm length, 1.1cm width
Lip: 1.5cm length (curled), 2.5cm length (uncurled), 1.1cm width

9 evenly-spaced flowers and 5 buds on an upright inflorescence measuring 43cm in length. Petals and sepals light green with reddish-brown speckles at base; column lemon-green; lip green-yellow with yellow patches; lip curled under; callus ridge yellow; texture waxy; substance firm. Noted for sweet, citrus-like fragrance.

According to George's notes, Cym. lianpan is presently considered by the botanists/taxonomists to be synonymous with Cym. goeringii. With such an interpretation, Cym. (goeringii x lowianum)=Cym. Eastern Morning, registered by Mukoyama in 2003 (see http://www.rhs.org.uk/plants/registerpages/orchiddetails.asp?ID=133801). Mukoyama has recently (December 11, 2008) registered the cross Cym. Tiger Morning (=Eastern Morning x Tiger Tail).

However, in "The Genus Cymbidium" by DuPuy and Cribb (2007), Cym. lianpan is annotated as being a variety of Cym. tortisepalum (pg 310), not Cym. goeringii, e.g. Cym. tortisepalum var. lianpan and Cym. tortisepalum var. longibracteatum. See Table 19 (pg 312) for a comparison between Cym. goeringii, Cym. tortisepalum and Cym. ensifolium.

RHS has no registration of Cymbidium hybrids having Cym. lianpan as a parent, but does identify at least one hybrid with Cym. tortisepalum as a parent. It's up to the experts and administrators to settle any controversy...

Given that Cym. lowianum is part of this grex's pedigree, one would expect the presence of lowianum's "V" mark at the mid-lobe of the lip, which seems to be a dominant trait. Such is found if one uncurls the lip, as shown below.
