[Taxacom] Salvadoraceae paraphyletic? (was: North America...)

[Michael Heads]

Hi Ken,
 
The ones I cited were just examples from papers that happened to be on my desk this morning - you can find many others in publications by myself and authors such as van Steenis. The terranes I mentioned are large igneous plateaus mostly erupted under (shallow) water. However, they include sedimentary strata intercalated in some of the basalts and some of these include wood fossils.

Hi Michael,
       If such groups are "quite common", I am surprised that your list
of examples is so short.  And as for central Pacific terranes, I am
unable to figure out what you mean by "some including wood fossils".

      Trans-tropical Pacific groups in New Guinea and tropical America
(matching Bataceae) are quite common. Examples include the plant groups
Polygalaceae tribe Moutabeeae and a clade in Monimaceae (both from
molecular studies), and the spider Masteria (from Platnick's website).
The disjunction may involve central Pacific terranes (some including
wood fossils) that accreted westward to New Guinea etc., eastward to the
Caribbean, Colombia etc.
