INTRODUCTION vii 



ninae is made up from four of my plates of Dendrochilum species, from 

 which Dr. Kranzlin has selected all the lips and two plants in full. One 

 of the plants, designated by the letter Q, is said to represent my concep- 

 tion of D. tenuifolium. This is an error, as the plant in question is taken 

 from my illustration of D. graminifolium. Fig. 37 of the Coelogyninae is 

 borrowed without permission from fascicle 1 of Orchidaceae. Although 

 considerably altered through redrawing, no mention of this fact is made. 

 In the legend that accompanies this figure, the letters J and K are said to 

 indicate the columns of D. sphacelatum and D. tenellum. Unfortunately 

 this is a most confusing blunder, as in culling out the analytical drawings 

 from my plates, side views of the lips have been selected to represent 

 columns in the figure ! 



In the " Conspectus subgenerum generis Dendrochili " on page 87, five 

 subgenera are admitted by Drs. Pfitzer and Kranzlin. I call attention 

 to this Conspectus, as the hasty inclusion in the Coelogyninae by Dr. 

 Kranzlin of the species illustrated by my plates numbered 21, 22 and 23 

 has brought about a state of things well nigh chaotic. In order to make 

 this statement clear, I here include a copy of the Conspectus. 



CONSPECTUS SUBGENERUM GENERIS DENDROCHILI 



A. Scapus heteranthus v. rarissime in eadem specie heteranthus et synanthus. 



a. Vagina singula sub pseudobulbo ab internodiis rbizomatis parum diverse 



Subg. I. Monochlamys. 



b. Vaginae plures sub pseudobulbo Subg. II. Eudendrocbilum. 



B. Scapus synanthus v. hysteranthus. 



a. Lobus medius labelli lateralibus interdum prorsus obsoletis major. 



a. Stelidia conspicua Subg. III. Platyclinis. 



#. Stelidia rudimentaria v. nulla Subg. IV. Aphanostelidion. 



b. Lobus medius labelli lateralibus minor Subg. V. Acoridium. 



The subgenus Acoridium as it is defined appears to have been originally 

 intended to include D. tenellum^ the type of the group, and probably 

 D. sphacelatum. This fact must have been overlooked by Dr. Kranzlin 

 when D. turpe, which has minute lateral lip-lobes, D. ocellatum, the lip 

 of which is entire, D. oliganthum, in which the lateral lip-lobes are want- 

 ing, and D. Merrillii, in which the lateral lobes are much reduced (all 

 species studied by means of my plates), are admitted to the subgenus 

 Acoridium as defined in the Conspectus. It also becomes apparent that 

 the subgenus Aphanostelidion is seriously modified by a consideration of 



1 On page 1G (Coelogyninae) Dr. Kranzlin refers to D. junceum Reicbb. (a plant conspecific 

 with D. tenellum) as known only through Reichenbach's description in Otia botanica Ham- 

 burgensia. Fortunately this is not so, as a duplicate type is to be found in the Gray Herbarium 

 and another specimen in the U. S. National Herbarium.
