Philodendron williamsii. It isn't what most

From: lbmkjm at yahoo.com (brian lee) on 2008.04.15 at 20:02:38(17391)
Dear Steve,
Aloha. I think that a lot of the confusion of
Philodendron williamsii, Philodendron spiritus-sancti,
and Philodendron stenolobum arise out the geography of
the area.
+More
First of all, the name P. spiritus-sancti is derived
from the state of Espirito Santo, Brazil.
Philodendron spiritus-sancti is found near the town of
Domingo Martins, Espirito Santo state, Brazil. North
of this town is the town of Santa Leopoldina...a
source of much confusion for a host of Philodendron
horticultural names. Further to the north is the town
of Santa Theresa....which is where the Augusto Ruschi
Museum is. I do not know the exact limits of the
distribution of Philodendron stenolobum , but we found
it as we approached the region of the Rio Doce, in
Espirito Santo state. At the time, Philodendron
stenolobum was thought to be Philodendron williamsii
because Simon Mayo was actively working on
Meconostigma. I met him at Roberto Burle-Marx's sitio
before he published his treatment. In fairness to
Simon Mayo, he had to work with only a few specimens
and incomplete material. He also thought that the
Espirito Santo state plants differed from the
Brazilian state of Bahia population...which is where
the true Philodendron williamsii is found. Bahia
state is to the north of Espirito Santo state.
Northern Esprito Santo and Southern Bahia have a
really interesting floral link. To add to the
confusion, Philodendron stenolobum has been referred
in the horticulture trade as Philodendron 'Espirito
Santo'.
I hope this clarifies the situation a bit.
Aloha,
Leland

Dear Aroid-l,
Aloha. I thought I should give the two references
which would clarify this question of Philodendron
stenolobum and Philodendron williamsii. They are
both species of the subgenus, Meconostigma, and are
written up in the following publications.
Dr. Simon Mayo of KEW, wrote the revision of the
subgenus, Meconostigma in 1991. He did not split
Philodendron stenolobum from Philodendron
williamsii...but he did note the differences and
thought that two taxa may be involved between the
Espirito Santo state plants and the Bahia state
populations. He did not have the fertile material of
Philodendron stenolobum to compare.
Mayo, S.J. 1991. A Revision of Philodendron subgenus
Meconostigma (Araceae). KEW Bull. 46 (4):601-681.
Dr. Eduardo G. Gonsalves, described Philodendron
stenolobum as new in 2002.
Gonsalves,E.G. & E.R. Salviani , 2002. New Species and
Changing Concepts of Philodendron subgenus
Meconostigma (Araceae). Aroidiana, Vol 25. pp. 2-15.
If there are disputes, these treatments should clarify
them.
