MR. R. ALLEN ROLFE ON THE GENUS VANILLA. 451 
fruit figured by De Vriese is characteristic of V. Pompona, and 
the bracts quite different from those of his flowering specimen. 
The flowers and fruit of both Species are now well known, and 
the confusion is therefore evident. Grisebach changed the 
name to Vanilla anaromatica, evidently on the ground that the 
fruit is not aromatic, but wrongly excluded V. guwianensis 
(probably because of the fruit) and Catesby’s figure (‘ Nat. 
Hist. Carol.,’ i. App., p. 7, t. 7). In Martius’s ‘Flora Brasi- 
liensis,’ V. aromatica and V. guianensis are kept distinct by 
Cogniaux, but four specimens representing V. organensis, Rolfe, 
are included under the former, and the description is evidently 
partly drawn from them. V. inodora, Schiede, was described 
from fruiting specimens which belong here, and as the name 
is the earliest correct one which was applied to the species it is 
here adopted.

Distinguished from the preceding by its more slender stems 
and racemes, and its smaller flowers with narrower segments.
