ABSTRACT
Monstera Adans. (Araceae: Monstereae) is revised for Costa Rica. Thirty-five species
are recognised, of which one (M. deliciosa) is
introduced. Of them, ten have been only very recently described and Monstera
tablasensis M.Cedeño
is described as new here. A key to the species is provided, and each is
illustrated. Lectotypes, epitypes or neotypes are
newly designated for Philodendron pertusum Kunth & C.D.Bouché (the basis
of Monstera lennea K.Koch),
P. anatomicum J.H.Morsch,
M. borsigiana K.Koch,
M. dubia (Kunth)
Engl. & K.Krause, M. punctulata (Schott)
Schott ex Engl., M. tenuis K.Koch, and Marcgravia paradoxa W.Bull
ex G.W.Johnson & R.Hogg.
Problems with the typification of Monstera adansonii
ssp. laniata (Schott) Mayo & I.M.Andrade (Tornelia
laniata Schott) are outlined.
