The synonymy given above indicates the history of the 
Philippine species which Rolfe described as Acoridium Whit¬ 
fordii. It was first obtained by Wallis from “ Manila ” and 
published as a new Coelogyne by Reichenbacb. From 
Reichenbach’s description it was quite impossible to identify 
the species. Pfitzer in his monograph of the Coelogyninae 
referred it to Pholidota, stating that he had not seen the 
type. In 1905, Rolfe identified a Philippine orchid collected 
in Luzon as a new species for which he proposed the name 
Acoridium Whitfordii. 
In my herbarium there is a specimen from the original 
Wallis collection, for which I am indebted to the Director of 
the Botanische Abteilung des Naturhistorischen Museums, 
Vienna. I also possess a tracing from the type preserved in 
Reichenbach’s Herbarium. The Wallis specimen proves to 
be similar to the specimens from Luzon from which Rolfe 
drew his description of Acoridium Whitfordii. 
Our present knowledge of the species indicates that it is 
confined to Luzon.

The deeply saccate labellum of this extraordinary 
species is unusual in the genus. It exhibits an extreme 
development of a tendency toward concavity of the labellum 
which is one of the traits of Acoridium, and in its inflores¬ 
cence suggests such species as Acoridium Wenzelii. 
My knowledge of this species is based on material cul¬ 
tivated in Hort. Munchen-Nymphenburg, said to have come 
from the type plant. For this material I am indebted 
to Dr. Rudolf Schlechter.
