the apex; flowers bright yellow, with a suddenly-constricted tube, but the limb 
less distinctly bilabiate than in the type, with all the segments more oblong and 
obtuse. Baker, Handb. [rid. 167. ‘Tritonia odorata, Lodd. Bot. Cab. t. 1820. 
Var. y, F. alba (Baker, Handb, Irid. 167); leaves, inflorescence and spathe- 
valves as in 8; flowers larger, pure white, with the tube narrowed more gradually 
downwards, the limb very indistinctly bilabiate, and all the segments obtuse and 
nearly equal.

The above are the three principal types, which I have characterized mainly 
from detailed notes kindly furnished by Prof. M. Foster. F. ganthospila, Klatt 
in Linnea xxxiv. 673 (Gladiolus canthospilus, Red. Lil. t. 124), differs mainly 
from alba by its suddenly-constricted perianth-tube, and F. Leichtlinii, Klatt in 
Regel Gartenjt. ¢. 808, by the same character and its large pale-yellowish flowers.
