On the
identity of Arum montanum

pertaining to Englerarum Nauheimer & P.C.Boyce (Araceae).

ABSTRACT
The
long-misinterpreted Arum montanum Roxb. is shown to be a species of Englerarum
Nauheimer & P.C.Boyce (Araceae–Aroideae). It is proposed that its
originally stated Indian provenance is a mistake and that it more likely came
from Myanmar, from where Englerarum is newly recorded here. The frequently
misapplied name Alocasia gageana Engl. & K.Krause, based solely on
an unpublished illustration of a cultivated plant from Myanmar, is also shown
to belong in Englerarum. The new combination Englerarum montanum (Roxb.)
P.C.Boyce, K.Z.Hein & A.Hay is made. Alocasia gageana, Englerarum
hypnosum (J.T.Yin, Y.H.Wang & Z.F.Xu) Nauheimer & P.C.Boyce and Alocasia
lihengiae C.L.Long & Q.Fang are placed in its synonymy. Arum
montanum Roxb. is lectotypified.
