The "date of effective publication" is the first day on which a piece of
literature is made accessible to the public (and *not* the day of printing,
mailing, etc.). I myself have bought a specimen of "Der Palmengarten" on
11th of October, 1992 in Frankfurt. Thus, the date of effective publication
of "Der Palmengarten" was clearly before 12th of October. I have evidence
that it was available as early as 7th of October (the date of effective
publication of "Phytologia").
As long as I cannot prove "Der Palmengarten" to have been published
*before* 7th of October, 1992 (of course, as my paper appeared in Europe,
and Lowrie & Carlquist's appeared in America, there would remain a tiny
micro-priority of a few hours, but this is not significant for the ICBN),
I'll accept Cheek's conclusion (he rather selects one name of two with *at
least equal* priority than to prove one of them to *have* priority), but I
cannot accept his premise (which is wrong) nor his line of reasoning (which
is the opposite of thorough botanic work):
>So, Martin Cheek claims that by 5 days, _D. citrina_ is now the valid name.

PS: Yes, Carlquist at least was at Rancho Santa Ana Bot. Garden. Barry: how
do your lables look like now? What a mess!
