eee SSIS. EN TANS aa 
The plants from which our figure of this species of Triumfetta was taken, were raised by Mr. Lambert from seeds 
thirty years old, obtained from a specimen collected in Peru by M. Pavon. , 
The racemes of flowers frequently become more elongated than we have represented them, and particularly so in 
West Indian specimens ; owing, no doubt, to the difference in temperature of -different places. There is not much 
beauty in the plant, unless it is very profusely in flower ; when the contrast between the little yellow blossoms and 
; very dark green leaves is agreeable enough. | oe | 
The discus is placed on the outside of the base of the stamens, and exhibits the appearance of a little membranous 
hairy cup. ‘The hooks of the surface of the ovarium consist of two unequal joints ; the terminal one much smaller. 
than the other, and curved like the claw of an insect. 
EXPLANATION OF THE PLATE,
