Under Vanda multiflora it has been attempted to show the necessity of separating from the genus Vanda certain 
species hitherto referred to it, and among others the V. teretifolia of this work. They differ from Vanda in the form 
and structure of their labellum, which is never saccate, but has always a spur with one or more appendages in its in- 
side, in the texture of their perianthium, and in habit. The plants which agree with Sarcanthus as above defined 
are Vanda teretifolia and paniculata, an unpublished species (Surcanthus succisus) from China, and probably some 
plants at present referred to Aerides. Vanda trichorhiza of Hooker (which is nearly allied to, if not the very same as, 
Epidendrum triste of Forster), and Aerides Arachnitis of Swartz, appear to be species of Cymbidium, a genus which 
differs from Vanda in scarcely any thing beyond the absence of a spur from the lip, and in the articulation of the 
latter with the columna. 
A native of China, whence it was imported by the Horticultural Society in 1821. Our figure was made in the 
month of June 1822, from a plant in the possession of Wm. Cattley, Esq.
