It appears that the tree long known as Luehea speciosa Willd. has now
been found to have been earlier described as Cedrus alternifolia Mill.,
later Swietenia alternifolia (Mill.) Steud., and has become Luehea
alternifolia (Mill.) Mabb.

Has there been any proposal to conserve Luehea speciosa Willd.?

Haven't heard of one..., and there's nothing on the web. All I found
was:

http://www.mobot.org/MOBOT/research/...jan04lit.shtml

which says

"Mabberley, D. J. 2002. The identity of Swietenia alternifolia (Mill.)
Steud. ('Meliaceae'). Gard. Bull. Singapore 54: 253-255.

Here is a shocker, and one that managed to slip by us first time around.
The name Swietenia alternifolia (Mill.) Steud. (based on Cedrus
alternifolia Mill.) had been rejected from Meliaceae (in Pennington &
Styles, Fl. Neotrop. Monogr. 28: 385, 405. 1981), but there the matter
rested until now. Older names in limbo status are always intriguing,
and this one proves to be no exception. The original description of
Cedrus alternifolia was based on plants grown in England from seeds
collected at Campeche (Yucatán), supplemented by the field notes of the
collector, William Houstoun. Neotypification of the name is here
achieved on the basis of a recently discovered Houstoun collection from
Campeche at BM, appropriately annotated and unequivocally identifiable
as the sp. long known throughout the Neotropics as Luehea speciosa
Willd. (Tiliaceae, or Malvaceae s. l.). In fact, Miller's name predates
Willdenow's by over 40 years, prompting the new combination Luehea
alternifolia (Mill.) Mabb., which becomes (at least for the time being)
the correct name for the sp."
