Esmeralda Sanderiana, Beichb. f. (sub V. Sanderiana), in Gard. Chron. I. c. 588. 



Of more than a dozen species of Vanda figured in this 

 work, there is not one with which this superb plant here 

 figured can claim any close affinity, except perhaps with V. 

 Gathcartii (Tab. 5845), now referred to another genus by 

 Reichenbach, Esmeralda (Ken. Orchid, ii. 38). Both these 

 have very broad flat sepals and petals, both want the 

 spur at the base of lip so almost constant a feature in 

 Vanda proper, and there is in both transverse coloration of 

 the perianth. They differ, however, remarkably in their 

 leaves, those of V. Cathcartiibeing soft, almost flaccid, with 

 rounded unequally 2-lobed tips, whilst those of V. San- 

 deriana are hard, rigid, with the truncate cuspidate tips 

 so usual in typical Vanda. Bentham (in Gen. Plant, in. 

 573) has referred V. (Esmeralda) Cathcartii to Blume's 

 genus Arachnanthe, which differs from Vanda in the lip 

 being jointed on to the base of the column, and neither 

 saccate nor spurred at the base, though sometimes shortly 

 spurred or gibbous at the back of the middle lobe. The 

 insertion of the lip appears to me to be the same in V.
