and D. luzonense passes into the broadly lanceolate leaves of D. Merrillii 

 through such species as I), graminifdfium, I), tenuifolium, I), turpi and 

 I), philippinense. The calli on the labellum of D. tenue, I), parvulum 

 and D. ventutulum 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 distind genua with the species of § Acoridium. 



Through an unfortunate oversight on the part of Dr. kranzlin, who 

 completed the Coelogyninae for "Das I'rlanzenreich," left unfinished by 

 Dr. 1'litzer. the titles on my plates of Dendrochilum species were over- 

 looked. These plates were practically duplicates of the set prepared for 



Fascicle I I id' "Orchidaceae," and were loaned to Dr. Kranzlin to facilitate 



hie 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 Acoridium would he 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 ell'ect that the loaned plates were inscribed with the generic name 

 Dendrochilum. Dr. Kransdin's work preceded mine, for which the plates 

 were prepared, and consequently the changes in "Orchidaceae" Pasc. II. 



which were made at the end of the introduction were necessarv. Dr. 

 Kranzlin himself directed my attention to his unfortunate oversight.
