This variety was described to accommodate
specimens of Hirtella racemosa that are distinctly
hispid on the young stems. It has the large
leaves characteristic of var. racemosa but the
long thin pedicels characteristic of var. hexandra.
The latter character is almost constant to separate
the two varieties, although a few collections
placed in var. racemosa have long thin pedicels
(e.g., Chagas 1252, INPA, NY). The above material
is obviously closest to H. racemosa and is
best regarded as a variety until further collections
and field studies are made.
