centre. — —Monstrous State. This has heen observed 

 to sport in the same way as C. tridentatum. A case is 

 mentioned in the Botanical Register for 1840, misc. 157. 

 where the scape became three times as stout as usual, 

 the length of the raceme much reduced, the sepals and 

 petals retaining their form and colour ; but the labellum, 

 instead of being arrow-headedj flat, deep purple, toothed 

 at the base, and placed in front of the flower, was of 

 exactly the same form as that of Monachanthus viridis, 

 hooded, undivided, and of a dull greenish colour tinged 

 with dull purple. The column too, in like manner lost 

 its cirrhi, shortened, and its lengthened beak disappeared.

25. C. lanciferum (Lindl. in Bot. Reg. 1841. t. 5. f. 5.) ; 

 petalis maculatis lineari-lanceolatis sepalo dorsali con-

 versus saccato sub sacco cornu tripartite instructo, sub 

 apice lamina lineari-lanceolata aucto, columnae cirrhis 



vix columna longioribus. Brazil. Very like C. 



cristatum ; but the margin only of the lip is broken up 

 into fringes ; and at the point is a broad lancet-shaped 

 spine.
