Dear Ms Freire-Fierro:
As you are aware, the problem with Nuttall types is that they can be in
one of two places, PH and BM, if the name was proposed by Nuttall himself
in one of his own publications (including the 1813 Catalog), or also at GH
or less frequently NY if the name was established for Nuttall by Torrey or
To determine if the specimen at PH is a holotype or should be designated
as a lectotype (or has already been so designated) is not a simple task.
Library work is critical and necessary. However, Ewan's designation of the
Nuttall collection as "type" under the rules today can be taken as an
effectively lectotypification. This is the most logical route to take for
one can not be certain exactly where Nuttall's specimens gathered in
Missouri (mainly in 1811) might be. It has been traditional to consider
the types mentioned by Nuttall in 1818 to be at PH, but after that for
them to be at BM. While you can prove that the Missouri collection is not
at BM, you can not prove that it is not somewhere else.
Thus, in my opinion, it is probably best to consider Ewan's informal
designation of the PH specimen as an effective lectotypification as this
removes any uncertainty.
