I am quite "arable to distinguish satisfactorily Reicbenbacb's tbree 

 species, (7. iindulatum, Wendlandonim^ and Mannii^ and doubtfully 

 refer the plant here figured to the latter. It is copied from the type, a 

 solitary specimen in the Kew Herbarium. According to Reichenbach's 

 descriptions, (7. undidatum has undulate leaves, oblong sepals, orbi- 

 cular lateral lobes, a concealed obscurely 3-lobed raidlobe of the 

 lipj and a globose spur ; G. Wendlaiidorum is a much larger plant, 

 with (according to a drawing in Herb, Calcutt,) hairs on the lip (but 

 which I have not found on any specimen that I have examined). 

 I suspect that G. Mannii may be a small state of it. 



The resemblance in the lip, its dorsal scale and ventral forked 

 callus, to the same orf^an in G. andamanicum (Plate 2140) is obvious. —
