Discussion
Type. Karsten sn, Venezuela, Cumbre de Valencia b. Pt. Cabello (LE).
Original material of Bactris setulosa, consisting of a leaf-fragment, a rachilla, and fruits, could be studied at Leningrad. This material matches the Guayana Highland specimens very well which are considered to be conspecific. The area of the species extends to Trinidad: B. cuesa and B. circularis are mere synonyms and belong here. The last-mentioned was separated mainly because its short-armed internodes alternating with the smooth greyish leaf-scars, a feature of the immature stem just below the crown which does not indicate a specific difference. The separation of B. bergantina based on characters like “minutely buff-brown furfuraceous nerves of the lower surface” of the pinnae, “the flattened or nearly flattened spines on the rachis of the petiole,” etc., is not worthwhile in my opinion either.
