Frederick Sander 'Ruiter' 2n

Not bred in the 1920's, Bert's from 2017! The cross of Isabel Sander with Cym. i'ansonii, see the magnificent spike and the distinctive lip which tells knowledgeable hybridizers that Cym. lowianum is not the same species as Cym. i'ansonii!!!

I would have this flower in my collection, lovely.

[Australis]

Seconded, Gary.

I often look back at the quality research undertaken by scientists in the 1950's and 1960's, and lament the downward spiral thereafter. Seems we knew a heck of a lot more from that period than we do now, as illustrated by the following (note reference to Cym. i'ansonii).

The degree of chromosome homology or non-homology has
been used to determine cytogenetic and estimate phylogenetic relationships
between the parent species. Wimber (1957c) showed evidence of a striking
homology between the genomes of the parents of the primary hybrids _C.
Gottianum (C. eburneum x C. insigne), C. Eburneo-lowianum (_C. eburneum
x C. lowianum), and C. Lowio-grandiflorum (C. lowianum x C. grandiflorum) .
He also presented evidence of an evolutionary divergence of the genomes
of the parents of the primary hybrids _C. Pauwelsii (C. insigne x C.
lowianum), C. Ceres (Cl. i' ansonii x C. insigne), and C. Lotta (C. i' ansonii
x _C. lowianum) based on a relatively high percentage of non-homologous
chromosomes. Earlier, however, Wimber (1957b) demonstrated that a clone
of C. insigne was extremely irregular during meiosis producing an
abundance of univalents, fragments, and bridges. The species status of
C* i'ansonii is often questioned. Rolfe and Alexander (Crosby 1952)
believed that it is a natural primary hybrid of _C. lowianum and _C.
tracyanum. If _C. i1ansonii is actually a hybrid and if a meiotically
irregular _C. insigne was used, it would be expected to find some non-
homologous chromosomes in C. Pauwelsii, C. Ceres, and C. Lotta. Wimber's
(1957c) work also illustrated that there has been a strong divergence
of the genomes in C. pumilum and C. insigne and its allies. This
statement is based on his observations that all 5 of the _C. pumilum
hybrids he observed had highly disorganized and disrupted meiotic cycles
and that his attempts at hybridization with this group met with near
total failure. Wimber's results regarding _C. pumilum were verified by
Yeh (1962) who meiotically analyzed several _C. pumilum hybrids and
concluded that this?, species is a very distinct species both morphologically
and genetically compared to the large-flowered species such as _C. insigne
Rolfe, _C. lowianum Rchb. f., C. erythrostylum Rolfe, _C. parishii Rchb, f.,
etc. It was also shown that a very close genetic relationship existed
between _C. insigne and _C. parishii and that a fairly close genetic
relationship existed between _C. insigne and C. lowianum and C.
erythrostylum (Yeh 1962).

Don was the real deal! First, he loved Cyms and he was a brilliant Scientist for a bonus. One of my saddest memories was finding some genetic anomaly at Geyserland and heading to the phone to call Don and then realising he had died two weeks previously. His wife used to do research at Sydney so Don would tag along and he was out running, as he always did, stopped for a coffee at Starbucks and dropped dead. What was interesting was that he told me all his family had a congenital heart condition and that's why he ran Marathons to hopefully extend his life. He shared with me that he was the oldest male in three family generations, living to 67.

He also told me that Dr. Walter Bertsch followed him as a special scholar at So Cal and it was Bertsch who got access to Gavino Rotor and Everest McDade's clonal details at Rivermont who had hired him as an advisor. Bertsch stole the info, took it with him when he did a post-Doc at Cambridge and traded it to Maurice Lecoufle. All that bullshit about Morel was cover-up for the theft. This was also personally confirmed to me by both Gavino and Everest!
