Yes, a change in environment does lead to evolution, as species adapt to
those changes...incrementally, as those most suited to the changes evolve.
Now ...as to the speed of these incremental changes...when evolution occurs,
it occurs very rapidly..in geologic time. In other words, while a

Well, now. Let's not paint Old Man Holttum black yet. I've received the

it is. So no stone tossing! Indeed, on going back through old OLDs OGDs

re "vandas in situ"... if our gardens here are an acceptable substitute, c'mon down to Homestead and visit us. We have all kinds of epiphytic orchids (species and hybrids) in the trees on the property, including vandas and other vandaceous genera, cattleyas, dendrobiums, oncidiums, grammatophyllums

orchid roots is:

I will try this question again. Has anyone used the e-AOS Awards

program since it includes photos.

Title: Holttum.
Kathy, at least he could get published in the Bulletin at a time when there was a lot more pressure on space for articles than there is now! I knew him when he was very much in his dotage (he lived to 95) but he had little practical knowledge of orchid culture. His physiology
Yeah, that was my first thought, too. But then I've never seen vandas
growing in situ. And you know how accomodating orchids are to culture.
Holttum wrote 4-5 articles on Sarcanths in the AOS Bulletin, so I assume he
was well known/respected in the orchid world at the time.

Interesting! But, if we have to believe in this, then what to say about
Vandas with their roots hanging in the air, the same occuring with countless
of other thin rooted orchids like Rodriguezias, many Oncidiums and so
on?

The AOS Bulletin has several articles by Mr Holttum, however not that one.
There's nothing in the ODC, either. Can anyone please scan the article and

Any plant biologists still reading this group? Does anyone

I fail to see where the fuss is centered. If you buy a Phalaenopsis in bloom and place it in your home or office away from an outside light source and fail to water it, the plant will last in beautiful bloom for at least a month. The buyer is still getting at leas

very useful point; whatever it is that causes changes in 'our time', they
are very rapid by 'usual' geological rates. The rate at which species are
becoming extinct is considered by some to be about the same as at the famous
