same character as the Roan, but on a smaller scale, and with 
the pasturage of its summit more closely fed down. We 
were not rewarded, however, with any new plants, and the 
cloudy weather obscured the prospect, which is said to be 
very extensive. On our return, we found Cedronella cordata, 
(Benth.) nearly out of flower, with runners often 2 or 3 feet - 
in length. Mr. Bentham has omitted to mention the agree- 
able balsamic odor of the genus, which in our plant is much 
less powerful than in C. £riphylla. We saw plenty of Cimi- 
cifuga Americana, but the flowers were still unexpanded. 
Our endeavours to obtain the fruit of Cimicifuga cordifolia 
(common in this region,) were likewise unsuccessful; without 
them it is not always easy to distinguish this species from 
C. racemosa. The leaflets of the former are frequently very 
large, the terminal ones resembling the leaves of the Vine in 
size and shape, as remarked by De Candolle, in one instance 
we found them 10 inches in diameter; but they are generally 
much smaller and more divided, apparently passing into 
the former species. The number of ovaries does not afford 
marked characters, since the lowest flowers of C. racemosa 
sometimes present 2, while the upper ones of C. cordifolia 
are almost always monogynous.
