Other claims from this paper (10)

Observation Two species groups were recognized based on pollen polarity.
Observation Exine ornamentation and aperture type were the most variable pollen traits.
Observation Reticulate-heterobrocate exine predominated.
Observation Other observed exine types were foveolate, rugulate, granulate, perforate, scabrate, microreticulate-echinate and microreticulate.
Observation Isopolar pollen occurred in two Eumachia species.
Observation Isopolar pollen occurred in two Psychotria species.
Observation Isopolar pollen occurred in one Rudgea species.
Observation Pollen apertures inform the circumscription of Palicourea.
Observation Inaperturate pollen predominated in Palicourea.
Recommendation Pollen results support transfer of certain Psychotria species to Palicourea.
