and D. luzonense passes into the broadly lanceolate leaves of D, Merrill 
through such species as D. graminifolium, D. tenwifolium, D. turpe and 
D. philippinense. he calli on the labellum of D. tenue, D. parvulum 
and D. venustilum are not characteristic of Acoridium as a whole and 
consequently are worthless in the consideration of generic segregation. 
After eliminating the characters which I have named there is nothing 
further, in my opinion, which may be reasonably regarded in an attempt 
to form a distinct genus with the species of § Acoridium. 
Through an unfortunate oversight on the part of Dr. Kranzlin, who 
completed the Coelogyninae for “Das Pflanzenreich,” left unfinished by 
Dr. Pfitzer, the titles on my plates of Dendrochilum species were over- 
looked. These plates were practically duplicates of the set prepared for 
Fascicle II of “Orchidaceae,” and were loaned to Dr. Kranzlin to facilitate 
his work on species which I had recently described. I believed that Dr. 
Kranzlin would understand from the legends on the plates that in my 
forthcoming volume Acoridiwm would be displaced by Dendrochilum. 
As it turned out Dr. Kriinzlin failed to observe the change in my work 
indicated by the plates and as a result an unlooked-for controversy ensued 
in which Dr. Kranzlin insisted? that the plates loaned to him were 
inscribed with the generic name Acoridium. Here again Dr. Kranzlin 
erred, as a subsequent examination proved the correctness of my assertion 
to the effect that the loaned plates were inscribed with the generic name 
Dendrochilum. Dr. Krinzlin’s work preceded mine, for which the plates 
were prepared, and consequently the changes in “Orchidaceae” Fasc. II, 
which were made at the end of the introduction were necessary. Dr. 
Krinzlin himself directed my attention to his unfortunate oversight.
