 Sprengel. Brazil. liaddi. Forbes. — Without being able to 

 determine exactly the plant of Humboldt, we have followed 

 Raddi, from whom we possess specimens, and whose des- 

 cription sufficiently accords with that of Humboldt. This 

 is an elegant species, of a soft and silky texture, dark green 

 above, pale beneath, stoloniferous, twice or thrice pinnatedly 

 branched, with the branches patent, and having the stem- 

 leaves equal in size, and equally closely placed with those 

 of the branches. The leaves are especially ciliated at the 

 base, where they are cordate, and, on one side, auricled.

Hab. Madagascar. Dr. Zya//, ("267.") — This has narrower 

 leaves than the generality of species of this division, of a 

 rigid texture, and glossy ; the whole plant does not exceed 

 4-6 inches in length.
