Has. Mexico. Humboldt. Peru. Henke. Porto-Rico. 
Sprengel. Brazil. Raddi. 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.

Haz. Madagascar. Dr. Lyall, (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.
