Specimens labelled "Species Blancoanae" are most likely collected by Merrill, E.D. to replace specimens originally described by Blanco, F.M. but which Blanco did not preserve.

Merrill wrote:

"In 1912 it occurred to me that, as Blanco preserved no botanical material, the preparation of an exsiccata to consist of specimens that should represent the various species described by him, as these were understood by me after long experience in the field and a critical study of each individual description, would be very desirable."
