Thanks for pointing this out. We've now corrected it.

There are actually 9 occurrences of the name (in HTML files) on our Web pages:

The Families of Flowering Plants: Description of Leguminosae-Caesalpinioideae
Genera of Leguminosae-Caesalpinioideae and Swartzieae: Index page
Genera of Leguminosae-Caesalpinioideae and Swartzieae: Description of Uittienia
Genera of Leguminosae-Caesalpinioideae and Swartzieae: List of Taxa Studied 
Genera of Leguminosae-Caesalpinioideae and Swartzieae: Classification
Genera of Leguminosae-Caesalpinioideae and Swartzieae: versions of the above 
in the French version of the data set

These come from 4 sources in our data; of course, these were propagated on 
our own computers, not on the Web.

Many of the occurrences on the Web came via the the list of names in 
http://pt.wikipedia.org/wiki/Caesalpinioideae, which evidently came from The 
Families of Flowering Plants, not from The Genera of 
Leguminosae-Caesalpinioideae and Swartzieae, because the former is cited. 
There is also a stub http://pt.wikipedia.org/wiki/Vittienia containing only 
automatically generated information. The error would probably have been 
picked up as soon as anyone entered information in this stub (provided they 
didn't take the information solely from our Web pages). I've corrected these 
Wikipedia pages. Derived pages such as 
http://dictionary.sensagent.com/vittienia/pt-pt/ will presumably be 
corrected automatically, eventually. The derived page 
http://www.melhordawiki.com.br/wiki/Vittienia is already correct, and 
is partially correct (its main heading still has the old spelling).

There are quite a few Google hits (out of the 35 or so) representing failed 
searches, e.g.

ITIS Results of Search in every Kingdom for Scientific Name ...
Results of: Search in every Kingdom for Scientific Name containing 
'Vittienia'. No Records Found.

Can anyone explain how this happens?

Another hit is a copy of an old version of one of our pages (a practice 
deprecated in http://delta-intkey.com/www/data-from-web-publications.htm):

The Families of Flowering Plants - Leguminosae-Caesalpinioideae Kunth
... Tessmannia, Tetraberlinia, Tetrapterocarpon, Thylacanthus, Trachylobium, 
Umtiza, Vittienia, Vouacapoua, Wagatea, Zenia, Zenkerella, Zuccagnia. ...

Finally, out of left field:

artic: wiki V-011-pt | Progressive Music & Classic Rock portal
(17320) Vittarville (17321) Vitteaux (17322) Vittefleur (17323) Vittersbourg 
(17324) Vittetia (17325) Vittienia (17326) Vittoncourt ...
